Error code P0135 on the dashboard Nissan indicates a problem with oxygen sensor (lambda probe) heater in bank 1, sensor 1. This malfunction occurs on models from Almera to X-Trail, but most often appears on cars with mileage over 100,000 km. Unlike the error P0130 (incorrect sensor signal), here we are talking specifically about heating circuit malfunction, which is critical for the correct operation of the fuel injection system.

Ignore P0135 impossible: when the heater is not working, the oxygen sensor takes longer to reach operating temperature (about 600°C), which leads to increased fuel consumption, unstable engine operation when cold and potential damage to the catalyst. In this article we will analyze all possible reasons errors, diagnostic methods (including checking with a multimeter) and repair options - from replacing the sensor to searching for breaks in the wiring.

What does P0135 mean on Nissan?

Code P0135 stands for "Heated Oxygen Sensor (HO2S) Heater Circuit Malfunction (Bank 1, Sensor 1)". Translation: Oxygen sensor heater circuit malfunction in the first bank (on the side of the 1st cylinder), the first sensor (before the catalyst). The heater is needed so that the lambda probe reaches operating temperature faster - without it, the sensor begins to work correctly only after the exhaust gases have warmed up, which takes several minutes.

On Nissan with systems OBD-II (all models after 1996) the error is recorded when:

  • 🔥 ECU detects open or short circuit in the heater circuit;
  • ⚡ The voltage on the heater is out of limits 0.3–0.7 V (the norm for most models);
  • ⏱️ The sensor warm-up time exceeds 2–3 minutes (depending on the ECU model).

It is important to understand: P0135 does not always mean that the sensor itself is broken. In 30% of cases, the problem lies in the wiring, fuses, or even the ECU firmware. For example, on Nissan Qashqai J10 with engine MR20DE the error often occurs due to oxidation of the contacts in the sensor connector, and on X-Trail T31 - due to a blown fuse #31 (15A) in the block under the hood.

Causes of error P0135

The list of possible causes can be divided into 3 groups: problems with the sensor itself, electrical circuit malfunctions and malfunctions of the computer. Let's look at each in detail.

1. Malfunction of the oxygen sensor (lambda probe)

The most common reason is failure of the heating element inside the sensor. Over time, the heater coil burns out due to:

  • 🔥 Overheating (if the sensor is installed too close to the exhaust or after a faulty catalyst);
  • ⚡ Power surges in the on-board network (for example, when “lighting” from another car);
  • 🛢️ Pollution combustion products of low quality oil or fuel.

On Nissan Note E11 And Micra K13 sensors often fail due to contact corrosion inside the connector. Symptom: The error appears periodically, especially in wet weather.

2. Wiring and power problems

The heater circuit consists of 4 wires (on most models Nissan):

  • 🔌 +12V (powered by relay or fuse);
  • 🔌 Weight (on the body or ECU);
  • 📊 Signal wire (to the ECU);
  • 🔥 Heater control (from the ECU).

Typical faults:

  • 🔧 Open or short circuit wires (often chafing against the exhaust manifold);
  • 💧 Oxidation of contacts in the sensor or ECU connector;
  • 🔌 Blown fuse (For example, EF15 on Nissan Tiida).

3. Malfunctions of the ECU or firmware

Less common error P0135 appears due to:

  • 🖥️ Incorrect firmware ECU (for example, after chip tuning);
  • 🔄 Memory failure control unit (solved by resetting errors or flashing);
  • 🔌 Bad contact in the ECU connector (oxidation or corrosion).
What oxygen sensors are installed on Nissan?

On most models Nissan (including Qashqai J10/J11, X-Trail T31/T32, Almera N16/G15) sensors with catalog numbers are used:

  • 22690-4M000 (original, for engines MR20DE, QR25DE);
  • 22690-4M010 (analogue for HR16DE);
  • NGK (NTK) 25090 or Denso 234-4207 (popular non-original substitutes).

Important: sensors before and after the catalyst vary! The first (bank 1, sensor 1) is always with a heater, the second (bank 1, sensor 2) is often without.

Symptoms of error P0135

Error P0135 may manifest itself differently depending on the severity of the malfunction. At the initial stage (for example, when contacts burn), the symptoms are almost unnoticeable, but over time the problem worsens.

Symptom Reason What to do
Lit Check Engine The ECU detected an error in the heater circuit Read codes with a scanner (for example, ELM327)
Increased fuel consumption (+1–2 l/100 km) The sensor warms up slowly, the ECU operates in “emergency” mode Check the heater with a multimeter
Unstable idle (speeds fluctuate) The ECU receives incorrect data on the composition of the mixture Diagnose the sensor and power circuit
Jerks during acceleration Rich/lean mixture due to false lambda probe readings Check signal wire and ground
Smell of gasoline from the exhaust pipe The ECU over-riches the mixture due to incorrect sensor data Eliminate the cause of the error P0135 and reset adaptations

⚠️ Attention: If together with P0135 errors appear P0171 (lean mixture) or P0172 (rich mixture), the problem is most likely sensor signal circuit, not in the heater. In this case, a comprehensive diagnosis is required.

How to diagnose P0135 yourself

To check you will need multimeter (preferably with dialing mode) and OBD-II scanner (even simple ELM327 for 500–1000 ₽). Diagnostics can be conveniently divided into 3 stages:

1. Check with OBD-II scanner

Connect the scanner and follow these steps:

  1. Count all errors (except P0135 there may be P0130–P0134, P0140–P0141).
  2. Look oxygen sensor readings in real time (Live Data). Norm:
    • Voltage: 0.1–0.9 V (oscillates when the engine is running);
    • Warm-up time: up to 1–2 minutes after launch.
  • Reset errors and check if P0135 again.

    • 2. Checking the heater with a multimeter

    Disconnect the sensor connector and take measurements:

    • 🔋 Heater resistance (between the heater contacts, usually 3 and 4):
      • Norm: 2–10 ohms (depending on the sensor model);
      • Break: ∞ (infinity);
      • KZ: 0 ohm.
    • ⚡ Supply voltage (between +12V and ground on the sensor connector with the ignition on):
      • Norm: 12–14 V;
      • If 0 V - Check the fuse and relay.

    1. Disconnect the oxygen sensor connector

    2. Ring the heater (resistance between 3 and 4 contacts)

    3. Check the voltage on the heater power supply (12V)

    4. Ring ground (pin 2, usually black wire)

    5. Check the signal wire (pin 1, usually gray)

    -->

    3. Checking wiring and connectors

    Inspect:

    • 🔍 Sensor connector for oxidation or corrosion;
    • 🔧 Wires from the sensor to the ECU (must not be frayed or melted);
    • 🔌 fuse heater circuits (on Nissan usually 10–15A, see the manual for location).

    ⚠️ Attention: On some models (for example, Nissan Patrol Y61) the heater circuit is protected separate relay (For example, EFI Relay). If power does not arrive, check its functionality.

    How to fix error P0135: step-by-step instructions

    The repair method depends on the cause of the problem. Below - algorithm of actions from simple to complex.

    1. Cleaning contacts and checking connectors

    If the error appears periodically (for example, after rain), the reason may be oxidized contacts:

    • 🔧 Disconnect the sensor and ECU connector;
    • 🧴 Clean contacts alcohol solution or a special liquid (for example, Kontakt 60);
    • 🔌 Check the tightness of the connector (sometimes the contacts “bend back”).

    2. Replacing the fuse or relay

    On most Nissan The heater circuit fuse is located:

    • B block under the hood (For example, F31 (15A) on X-Trail T31);
    • B salon block (For example, EF15 (10A) on Almera N16).

    If the fuse blows repeatedly, look for short circuit in the wiring.

    3. Repair or replacement of the oxygen sensor

    If the heater is faulty (resistance ∞ or 0 ohm), there are two options:

    • 🔧 Replacing the sensor (recommended for most cases). Original sensors for Nissan are worth 3000–8000 ₽, analogs (NGK, Denso, Bosch) — 1500–4000 ₽.
    • 🔥 Heater repair (only possible if the spiral breaks, requires a soldering iron and skills).

    ⚠️ Attention: When replacing the sensor necessarily use non-stick paste (For example, Liqui Moly Kupfer-Spray) on the thread. Without it, the sensor may “stick” to the outlet, and at the next replacement you will have to cut it off with a grinder.

    4. Checking and repairing wiring

    If the problem is in the wires:

    • 🔍 Find the location of the break or short circuit (often near the exhaust manifold);
    • 🔧 Restore the chain soldering (twisting is not allowed!);
    • 🛠️ Insulate the wires heat shrink tube (regular electrical tape will melt from the heat).
    💡

    If after replacing the sensor the error P0135 left, check connection polarity. On some models Nissan (For example, Pathfinder R51) the sensor connector can be inserted incorrectly - contacts +12V And mass will change places, which will lead to a repeated error.

    When to contact service

    Self-repair is not always possible. Contact the service if:

    • 🔧 You replaced the sensor, but the error remained;
    • 🖥️ Do you suspect ECU malfunction (for example, together with P0135 errors appear U1000, P0603);
    • 🔥 Yes mechanical damage wiring (melting, short circuit);
    • 📊 Needed ECU flashing (for example, after chip tuning).

    Cost of diagnostics in the service: 1000–2500 ₽. Repair (sensor replacement + circuit check) will cost 3000–10 000 ₽ depending on the model.

    💡

    If the error P0135 appeared after engine wash or heavy rain, most likely the problem is oxidized contacts or moisture getting into the ECU connector. In this case, it is enough to dry and clean the contacts - the sensor may be operational.

    FAQ: Frequently asked questions about error code P0135 on Nissan

    Is it possible to drive with P0135?

    Short term - yes, but not recommended. Driving for a long time with a faulty sensor heater leads to:

    • ⛽ Increased fuel consumption (+10–15%);
    • 🔥 Risk of catalyst damage (due to incorrect mixture);
    • 🚗 Unstable engine operation when cold.

    If the sensor is completely out of order (and not just the heater), you cannot drive - this will lead to serious damage.

    How to distinguish P0135 from P0130?

    P0130 - incorrect sensor signal (problem in sensitive element), and P0135 - malfunction heater. The symptoms are similar, but the diagnosis is different:

    • When P0130 check signal wire and the sensor itself;
    • When P0135 — heater circuit (power, ground, resistance).
    How long does an oxygen sensor last on a Nissan?

    Service life of the original sensor:

    • 🚗 80,000 – 120,000 km - for sensor before the catalyst;
    • 🚗 150,000 – 200,000 km - for sensor after the catalyst.

    The resource is affected by:

    • ⛽ Fuel quality (additives shorten service life);
    • 🛢️ Oil condition (oil getting into the combustion chamber kills the sensor);
    • 🔥 Engine overheating (exhaust temperature is higher 900°C destroys the sensitive element).
    Is it possible to clean the oxygen sensor?

    Theoretically yes, but the effect is temporary. For cleaning use:

    • 🧴 Phosphoric acid (soak for 10–15 minutes);
    • 🔥 Ultrasonic bath (in services).

    ⚠️ Attention: Cleaning only helps when carbon deposits. If the heater or sensing element is broken, the sensor must be replaced.

    Which oxygen sensors are suitable for Nissan?

    For most models Nissan fit:

    Model Nissan Original number Analogues
    Qashqai J10/J11, X-Trail T31/T32 22690-4M000 NGK (NTK) 25090, Denso 234-4207, Bosch 0 258 006 537
