Fault code P0135 on cars Nissan - one of the most common problems associated with the exhaust system. This error indicates Malfunction of the heating circuit of the oxygen sensor (lambda probe) in the first row (bank 1). Unlike the error P0130, which indicates a low sensor signal, P0135 specifically talks about problems with its heating element.

Most often the error appears on models Qashqai (J10/J11), X-Trail (T31/T32), Juke And Note with gasoline engines HR16DE, MR20DE or QR25DE. But it can also occur on diesel versions (for example, Navara with YD25DDTi). The main danger of ignoring this error is increased fuel consumption (up to 15-20%) and the risk of catalyst damage due to incorrect fuel mixture.

In this article we will look at:

  • 🔧 What does P0135 mean? and how does it affect engine performance?
  • 🔍 Top 5 reasons code appearance (from banal oxidation of contacts to sensor death)
  • 🛠️ Step-by-step diagnostics with and without a multimeter
  • 💰 Repair cost in the service vs self-removal

What is the P0135 code and why is it important?

Code P0135 stands for "Heated Oxygen Sensor (HO2S) Heater Circuit Malfunction (Bank 1, Sensor 1)". Translation: Malfunction of the oxygen sensor heating circuit (bank 1, sensor 1).

Heated lambda probe is installed in the exhaust manifold before the catalyst. Its task is to quickly (in 20-30 seconds) warm up to operating temperature (~600°C) and transmit accurate data on the oxygen content in the exhaust gases. If the heating does not work, the sensor begins to produce incorrect signals, and the ECU goes into emergency mode, enriching the fuel mixture.

Consequences of ignoring the error:

  • 🔥 Catalyst overheating due to rich mixture (may melt)
  • ⛽ Increased fuel consumption by 1-2 liters per 100 km
  • 🚗 Dips during acceleration and unstable idle
  • 💨 Increased exhaust toxicity (do not pass inspection)

⚠️ Attention: On some models Nissan (For example, Almera N16 or Primera P12) error P0135 may be accompanied by code P0130. This means that the sensor not only does not heat up, but is completely out of order. In this case, the lambda probe needs to be replaced.

Top 5 causes of error P0135 on Nissan

Reasons for the appearance of the code P0135 can be divided into two groups: electric (wiring or power problems) and mechanical (malfunction of the sensor itself). Let's take a closer look at them.

1. Open or short circuit in the heating circuit

Most often, the wires rub against the exhaust manifold or melt due to high temperature. On Nissan Qashqai J11 And X-Trail T32 The problem usually lies in the harness next to the catalytic converter. Also possible:

  • 🔌 Oxidation of contacts in the sensor connector (especially after washing the engine)
  • 🔥 Melting insulation due to its close location to the exhaust tract
  • 🐭 Damage by rodents (relevant for cars parked on the street)

2. Malfunction of the sensor heating element

The resistance of the heating coil in a working sensor should be 2-14 Ohm (depending on the model). If the multimeter shows 0 ohm (short circuit) or ∞ (break), the sensor must be replaced. On Nissan Juke And Note with engines HR16DE this is the most common cause of error.

3. Circuit power problems

The lambda probe heater is powered by a relay or fuse (usually 15A in the block under the hood). Reasons:

  • 🔋 Fuse burned out (on Nissan Almera G15 this is F30 in the mounting block)
  • 🔄 Relay faulty (eg relay K9 on X-Trail T31)
  • 🔌 Poor ground contact (often under the intake manifold)

4. Sensor contamination

If oil (due to worn rings or seals) or fuel (over-enriched mixture) gets on the working surface of the lambda probe, this can lead to:

  • 🛢️ Soot deposits, blocking the sensitive element
  • 🔥 Overheating and destruction of the ceramic base

5. ECU malfunction

It is rare, but it happens that the control unit does not properly control the heating circuit. For example, on Nissan Teana J32 with engine VQ35DE There have been cases of firmware “glitches” when the ECU mistakenly detected an open circuit.

Reason How to check Repair cost (RUB)
Open/short circuit in wiring Continuity test with a multimeter, visual inspection 500–2000 (harness replacement)
Sensor heater malfunction Spiral resistance measurement 2500–6000 (new sensor)
Power problems (fuse/relay) Checking the voltage at the connector 200–1000 (fuse/relay replacement)
Sensor contamination Visual inspection, cleaning 0–1500 (lambda probe cleaner)
ECU malfunction Diagnostics with a scanner, flashing 3000–10000
💡

On Nissan Qashqai J10 And X-Trail T31 with engine MR20DE error P0135 often appears after replacing the sensor with a non-original one. Use only sensors with article number 22690-4M000 or 22690-4M010 (for Euro-4/Euro-5).

How to Diagnose P0135 Without a Scanner

If you don't have a diagnostic scanner (for example, ELM327 or Launch CReader), error P0135 can be identified by indirect signs and the heating circuit can be checked manually. Here are the step-by-step instructions:

Step 1. Visual inspection

  • 🔍 Check it out sensor connector for the presence of oxidation or moisture.
  • 🔥 Take a look wiring for melting or chafing (especially near the manifold).
  • 🛢️ If the sensor is covered with soot or oily deposits, it needs to be cleaned or replaced.

Step 2: Check the supply voltage

You will need a multimeter in DC 20V:

  1. Disconnect the sensor connector.
  2. Turn on the ignition (do not start the engine!).
  3. Connect red dipstick to contact +12V (usually this is contact 1 or 3, see diagram for your model).
  4. The black dipstick is for engine ground.
  5. The voltage should be 12.0–12.6V. If not, look for a break or a blown fuse.

Step 3: Check Heater Resistance

Set the multimeter to mode 200 Ω:

  1. Disconnect the sensor connector.
  2. Connect the probes to the heater contacts (usually 2 And 4).
  3. Resistance must be within 2–14 Ω (see manual for exact values).
  4. If 0 Ω - short circuit if ∞ - break.

Step 4: Check the weight

Make sure that the ground contact of the sensor (usually the black wire) is securely connected to the body or engine. To do this:

  1. Connect one multimeter probe to the ground contact on the connector.
  2. The second probe goes to the negative terminal of the battery.
  3. There must be resistance 0 Ω.

Step-by-step instructions for resolving error P0135

After diagnosis, we begin repairs. Below is an algorithm of actions depending on the identified cause.

1. Oxidation or poor contact in the connector

If the problem is in the connector:

  1. Disconnect the connector and clean the contacts alcohol solution or a special cleaner (for example, CRC Contact Cleaner).
  2. Check the tightness of the contacts - they should not loosen.
  3. Apply to contacts dielectric grease (For example, Liqui Moly Electronic-Spray).

2. Break or short circuit in the wiring

If the wiring is damaged:

  • 🔧 For minor damage — insulate the breakage area with heat-shrinkable tubing.
  • 🔄 For severe meltdowns - replace the harness completely (part number for Qashqai J11: 24070-4M000).
  • ⚠️ Do not use regular electrical tape - it will melt due to temperature!

3. Sensor heater malfunction

If the heating coil is broken:

  1. Buy a new sensor. Original articles for popular models:
    • Nissan Qashqai J10/J11: 22690-4M000 or 22690-4M010
    • Nissan X-Trail T31/T32: 22690-AL500 or 22690-AL510
    • Nissan Juke: 22690-JK000
  • Use anti-stick paste (For example, Liqui Moly Anti-Seize) when installing, so that the sensor does not “stick” to the collector.
  • Tighten the sensor to a torque 40–50 Nm (do not overtighten!).

    • 4. Power problems (fuse/relay)

    If not +12V on the connector:

    1. Check the fuse (eg F30 (15A) on Almera G15).
    2. If the fuse burns repeatedly, look for a short circuit in the circuit.
    3. Ring the relay (on X-Trail T31 this is a relay K9 in the block under the hood).
    ⚠️ Attention: On some models Nissan (For example, Pathfinder R51) the lambda probe heating circuit is protected separate fuse in the cabin (not in the engine compartment!). Look for it in the fuse box behind the glove compartment or under the steering wheel.
    How to distinguish an original sensor from a fake?

    Original sensors Nissan have:

    - Logo NTK or Denso on the body

    - Clear marking of the article (for example, 22690-4M000)

    - Factory packaging with a hologram

    - Gray or black connector (counterfeits often have green or blue)

    Fakes are usually 30-50% cheaper, but last 10-20 thousand km.

    How much does it cost to repair it at a service center vs doing it yourself?

    Cost of fixing the error P0135 depends on the cause and region. Below are the average prices for Moscow and the regions (for 2026).

    Type of repair Cost of service (RUB) Cost yourself (RUB) Repair time
    Diagnostics with a scanner 1000–2000 0 (if there is ELM327) 30 minutes
    Cleaning the connector contacts 500–1500 200 (cleaner + lubricant) 20 minutes
    Wiring repair (soldering/insulation) 2000–4000 300 (heat shrink, solder) 1–2 hours
    Replacing the lambda probe (original) 5000–12000 3000–6000 1 hour
    Replacing the lambda probe (analog) 3000–7000 1500–3000 1 hour
    Replacing the fuse/relay 500–1500 100–300 10 minutes

    Do-it-yourself repairs are profitable, but require care. For example, when replacing a sensor with Nissan X-Trail T32 it is easy to strip the threads in the manifold if not used special key for lambda probes (article KTC 3230). Also, when soldering wiring, be sure to use heat shrink tube, and not electrical tape - it will melt from the temperature of the collector.

    If you are not confident in your abilities, it is better to contact the service. For example, on Nissan Juke with engine HR16DE The sensor is located in an inconvenient location, and replacing it may require removing the protection or even part of the exhaust tract.

    💡

    Saving on diagnostics can result in costly repairs! If after replacing the sensor the error P0135 remains, the problem may be in the wiring or the ECU. In this case, you cannot do without professional diagnostics.

    What not to do with error P0135

    Certain actions may make the problem worse or cause additional damage. That's what absolutely not recommended do:

    1. Reset the error without eliminating the cause

    If you just erase the code P0135 scanner or disconnecting the battery, it will return after 10-50 km. Moreover, long-term driving with a faulty sensor can:

    • 🔥 Lead to overheating and destruction of the catalyst (replacement cost - from 20,000 rubles).
    • ⛽ Enlarge fuel consumption by 15-20%.
    • 🚗 Call failures during acceleration and unstable idle.

    2. Use cheats or emulators

    Some owners install mechanical snags (manifold inserts) or electronic emulators lambda probe signal. This is fraught with:

    • 🚫 Refusal to undergo technical inspection (emulators are prohibited by law).
    • 🔧 Problems with ECU firmware (on new models Nissan emulators may cause errors P0420 or P0430).
    • 💨 Increased exhaust toxicity (harm to the environment and fines).

    3. Try to “reanimate” the sensor with heat or chemicals

    On the Internet you can find advice on:

    • 🔥 Heating the sensor with a gas burner - this destroys the ceramic element.
    • 🧪 Cleaning with phosphoric acid - it helps temporarily, but then the sensor fails completely.
    • 🔌 By supplying 12V voltage directly - you can burn the heating coil.

    These methods not restored sensor, but only delay its replacement.

    4. Ignore weight check

    Poor mass is one of the most common causes P0135 on Nissan. If you simply replace the sensor without checking the ground contact, the error will return. On Qashqai J11 And X-Trail T32 The mass point is often located under the intake manifold and is oxidized.

    ⚠️ Attention: On diesel Nissan (For example, Navara with YD25DDTi) error P0135 may appear due to faulty glow plugs. The fact is that on some models the lambda probe heating circuit is powered from the same relay as the spark plugs. Before replacing the sensor, check the spark plugs!

    FAQ: Frequently asked questions about error code P0135 on Nissan

    Is it possible to drive with P0135?

    Short-term - possible, but not advisable. Long driving (more than 200-300 km) will lead to:

    • Increased fuel consumption (up to 2 liters per 100 km).
    • Risk of damage to the catalyst (replacement cost - from 20,000 rubles).
    • Unstable engine operation (failures during acceleration, floating speed).

    If the error appears on the road, get to your home or service center, but do not delay repairs for long.

    Which oxygen sensor should I choose for replacement?

    We recommend original sensors or high-quality analogues:

    Model Nissan Original article High-quality analogue
    Qashqai J10/J11, X-Trail T31/T32 22690-4M000 or 22690-4M010 Denso DOX-0209, NGK 14090
    Juke, Note 22690-JK000 Bosch 0 258 006 537
    Navara, Pathfinder 22690-AL500 NTK 24291

    Avoid cheap sensors without a brand - they last 10-20 thousand km.

    Can P0135 be caused by bad gasoline?

    No, direct communication between fuel quality and error P0135 no. However, bad gasoline can:

    • Lead to sensor contamination soot (which will cause an error P0130, not P0135).
    • provoke catalyst overheatingif the sensor is already faulty.

    If after refueling appears Check Engineit's most likely another error (eg P0171 - lean mixture).

    Do I need to reset adaptations after replacing the sensor?

    Yes, after replacing the lambda probe it is recommended:

    1. Reset errors with the scanner (for example, ELM327 + program Torque Pro).
    2. Make reset adaptations (on some models Nissan this can be done through the on-board computer menu or scanner).
    3. Drive 50-100 km in gentle mode (without sudden acceleration) so that the ECU learns again.

    If you do not reset the adaptations, the engine may operate unstably for the first 10-20 km.

    Why does P0135 appear after washing the engine?

    Water getting into the sensor connector or wiring can cause:

    • 🔌 Short circuit in the heating circuit.
    • 💧 Contact corrosion (oxidation).

    What to do:

    1. Dry the connector with a hairdryer (not hot air!).
    2. Process contacts alcohol solution and lubricate Liqui Moly Electronic-Spray.
    3. Check the circuit with a multimeter (heater resistance and supply voltage).
