Error 0335 on <em>Nissan Almera N16</em>: complete analysis of the problem and solution

Error 0335 on Nissan Almera N16 - one of those problems that can unsettle even experienced car owners. It is connected to the engine management system and often manifests itself unexpectedly: the car begins to twitch during acceleration, loses power, or even goes into emergency mode. Unlike more common fault codes (eg. P0300 or P0171), error 0335 model specific Nissan with the system ECU Hitachi or Siemens, which were installed on Almera N16 2000–2006.

The main difficulty is that this code does not always clearly indicate a specific failure. It may indicate a malfunction of the crankshaft position sensor (CKP), and about problems with wiring, ECU or even mechanical engine components. In this article we will analyze all possible causes, diagnostic methods (including working with Consult III and a multimeter), and we will also give step-by-step instructions for troubleshooting - from a simple check of contacts to flashing the control unit.

What does error 0335 mean? Nissan Almera N16?

Code 0335 in the self-diagnosis system Nissan stands for "Crankshaft Position (CKP) Sensor Circuit Malfunction". However, this general definition does not reflect the full complexity of the problem. The point is that ECU logs an error when:

• 🔍 There is no signal from the sensor CKP for more than 2 seconds after starting the engine.
• ⚡ The voltage in the sensor circuit is outside the permissible range (usually 0.3–4.7 V).
• 🔄 The signal from the sensor is intermittent or has an unstable amplitude (for example, due to oxidized contacts).
• 🛠️ ECU detects discrepancies between sensor signals CKP And CMP (camshaft position).

It is important to understand that the error 0335 can be either primary (a real malfunction of the sensor or wiring) or secondary - when the problem lies in another node, but ECU mistakenly interprets it as a failure CKP. For example, a worn flywheel ring or a stretched timing belt can cause similar symptoms.

⚠️ Attention: If the error 0335 accompanied by code P0336 (sensor malfunction CMP), most likely the problem is related to desynchronization of the valve timing. In this case, it is necessary to check the timing marks and the condition of the belt.

In practice, owners Almera N16 encounter the following symptoms:

• 🚗 The engine stalls at idle or when releasing gas.
• ⚡ Traction disappears, especially at low speeds (up to 2500 rpm).
• 🔥 Lights up on the dashboard Check Engine, but the scanner only shows 0335.
• 🔄 The engine goes into emergency mode with the speed limited to 3000–3500 rpm.

Reasons for error 0335: from sensor to ECU

To effectively resolve an error, you need to understand its root cause. Below we have listed all possible sources of the problem, ranked by frequency of occurrence on Nissan Almera N16:

Reason	Probability, %	Diagnostic method
Sensor malfunction CKP (break, short circuit, wear)	40%	Checking resistance and voltage with a multimeter
Oxidation or damage to the contacts in the sensor connector	25%	Visual inspection, cleaning contacts
Break or short circuit in the wiring from the sensor to ECU	15%	Testing the circuit with a multimeter
Malfunction ECU (firmware failure, chip damage)	10%	Diagnostics on Consult III, flashing
Mechanical problems (flywheel wear, crankshaft pulley play)	10%	Visual inspection, checking clearances

Crankshaft position sensor (CKP) - the most vulnerable element. On Almera N16 Two types of sensors were installed: inductive (early models) and based on the Hall effect (later). Inductive sensors are more likely to fail due to overheating or vibration, while Hall sensors are more likely to fail due to contamination or corrosion of the contacts.

Wiring also deserves special attention. On Nissan Almera N16 sensor wiring harness CKP passes next to the exhaust manifold, which eventually leads to melting of the insulation. In addition, the sensor connector is not sealed and moisture can enter it, causing oxidation.

What to do if the error only appears when the engine is hot?

This is a typical sign of a bad sensor. CKP or weight problems. When heated, the resistance in the damaged circuit increases, which leads to signal loss. In this case it is recommended:

1. Check the resistance of the sensor on a cold and hot engine (should be stable within 500–700 Ohm).

2. Inspect the mass ECU and the sensor - often oxidation of the contacts occurs precisely when heated.

3. Check the sensor power circuit (+5 V from ECU).

How to diagnose error 0335: step-by-step instructions

Diagnosis of the error 0335 requires a systematic approach. Start with the simplest checks and gradually move on to more complex ones. You will need:

• 🔧 Multimeter (with resistance and voltage testing mode).
• 🔍 Diagnostic scanner (ELM327, Consult III or analogues).
• 🛠️ A set of screwdrivers and keys for removing the sensor.
• 🧴 Contact lubricant (CRC, WD-40) and contact cleaner.

Step 1: Reading Errors

Connect the diagnostic scanner to the connector OBD-II (located under the steering wheel, to the left of the brake pedal). Besides 0335, pay attention to the accompanying codes:

• P0336 - sensor malfunction CMP (indicates phase desynchronization).
• P0300 - multiple misfires (may be due to an error 0335).
• P0340 - sensor malfunction CMP (often appears along with 0335).

Step 2: Check the sensor CKP

The sensor is located on the oil pump cover (transmission side). To check it:

1. Remove the connector from the sensor and inspect the contacts for oxidation or damage.
2. Measure the resistance between the sensor terminals. For an inductive sensor the norm is 500–700 Ohm, for a Hall sensor - 1–2 kOhm.
3. Check the voltage at the connector with the ignition on (between +5 V and mass). No voltage indicates an open circuit or malfunction ECU.

1. Remove the connector and inspect the contacts

2. Check the sensor resistance

3. Measure the voltage at the connector (should be 5 V)

4. Check the circuit for open circuit (ring the wires to the ECU)

Step 3. Checking wiring and connectors

If the sensor is working, test the circuit from the sensor to ECU (contact 29 on the control unit connector). Please note:

• 🔌 Integrity of wire insulation (especially near the exhaust manifold).
• 🔗 Grounding reliability ECU (the ground wire is attached to the body under the battery).
• 🔄 No short circuit to +12 V or mass.

⚠️ Attention: On Almera N16 with engine QG15DE And QG18DE sensor CKP has three wires: +5 V, mass And signal. If there is no voltage on the signal wire when the starter cranks, the sensor is faulty.

How to resolve error 0335: from simple to complex

Depending on the diagnostic results, select one of the following troubleshooting methods. Start with the most accessible and cheapest methods.

1. Cleaning contacts and checking connectors

Often a mistake 0335 occurs due to oxidized contacts in the sensor connector or ECU. To clean:

1. Remove the connector from the sensor CKP and inspect the contacts. If there is green residue or corrosion, use contact cleaner (CRC Contact Cleaner).
2. Check the connector ECU (located under the glove compartment). Contact 29 must be clean and not deformed.
3. Apply a thin layer of dielectric grease to the contacts to protect them from moisture.

2. Replacing the crankshaft position sensor

If the sensor is faulty, it must be replaced. For Nissan Almera N16 original sensors fit Nissan 23731-4M000 (inductive) or 23731-4M010 (Hall effect). When replacing:

• 🔧 Use a socket wrench on 10 mm to unscrew the fastening bolt.
• 📏 Make sure that the gap between the sensor and the flywheel ring is 0.5–1.5 mm.
• 🔄 After installing the new sensor, reset the errors through the diagnostic scanner.

3. Wiring repair

If the problem is a broken or shorted wire, follow these steps:

1. Inspect the wiring harness from the sensor to ECU. Pay special attention to the area near the exhaust manifold.
2. If melted insulation is detected, replace the damaged section of the wire or the entire harness.
3. Check weight ECU — corrosion on the ground wire often leads to unstable operation of the sensors.

4. Flashing or replacement ECU

If all the previous methods did not help, the problem may lie in the control unit. On Almera N16 ECU often fails due to:

• 🔥 Overheating (the unit is located next to the stove).
• ⚡ Voltage surges in the on-board network.
• 🛠️ Incorrect connection during diagnostics.

In this case:

• Try to reflash ECU original firmware (required Consult III or Nissan DataScan).
• If the firmware does not help, replace the unit with a known good one (will do ECU from Almera N16 or Primera P12 with the same engine).

Common repair mistakes and how to avoid them

Many owners Nissan Almera N16 make typical mistakes when eliminating code 0335, which causes the problem to reappear. That's what it's impossible do:

• 🚫 Ignore related errors. For example, if together with 0335 present P0340, replace only the sensor CKP not enough - you need to check the sensor too CMP.
• 🚫 Install non-original sensors. Cheap analogues often have unstable characteristics, which leads to repeated error triggering.
• 🚫 Do not check the gap between the sensor and the flywheel ring. Gap too big (>1.5 mm) or metal shavings on the sensor may cause false alarms.
• 🚫 Reset errors without eliminating the cause. If you just erase 0335 through the scanner, it will return the next time the engine is started.

Another common mistake is failure to check sensor power supply. Many car owners change the sensor without making sure that it receives +5 V from ECU. If there is no power, the problem may lie in the control unit itself or in the power circuit.

It is also worth paying attention to connection quality. For example, after cleaning the contacts, some owners forget to fix the connector on the sensor, which leads to vibrations and re-oxidation. Use plastic ties to securely secure the wiring harness.

Prevention of error 0335: how to prevent recurrence

To make a mistake 0335 did not return after repair, follow these recommendations:

• 🔧 Check the status of your contacts regularly sensor CKP And ECU (every 20,000 km).
• 🛠️ Use dielectric grease to protect connectors from moisture and corrosion.
• 🔥 Monitor engine temperature. Overheating accelerates wear on sensors and wiring.
• ⚡ Monitor the on-board network voltage. Voltage surges can damage ECU.
• 📊 Reset adaptations periodically ECU. This helps to avoid the accumulation of errors in the block memory.

Pay special attention massive wires. On Almera N16 they often oxidize, which leads to unstable operation of the sensors. Once a year, clean the grounding points (under the battery, on the body next to ECU) and apply a protective coating to them.

If your vehicle is driven in conditions of high humidity or frequent temperature changes, consider installing additional protection to the sensor connector CKP. For example, you can use a heat-shrinkable tube or a special case.
