Error P0335 on the dashboard Nissan Qashqai — a signal about problems with the crankshaft position sensor (CPS). This small but critical element is responsible for synchronizing the operation of the fuel system and ignition. If the ECU (electronic control unit) detects incorrect signals or their absence, the engine begins to “triple”, loses power or refuses to start at all.

Owners Qashqai The first (J10) and second (J11) generations encounter this error most often after 100–150 thousand km, but sensor wear is not always to blame. The problem may lie in the wiring, contamination, or even mechanical damage to the flywheel ring gear. In this article we will analyze all possible causes of P0335, diagnostic methods (including without a scanner) and repair nuances - from replacing the sensor to checking the engine ground.

What does error P0335 mean on Nissan Qashqai

Code P0335 stands for «Circuit Malfunction in the Crankshaft Position Sensor» - Malfunction of the crankshaft position sensor circuit. Unlike the error P0336 (signal leaving the permissible range), here we are talking about the complete absence or distortion of the signal. ECU Nissan Qashqai receives data from DPKV for:

  • 🔹 Accurate determination of the moment of fuel injection;
  • 🔹 Controlling the ignition timing;
  • 🔹 Synchronization of camshaft operation (via phase sensor).

If the signal disappears, the control unit goes into emergency mode: fuel is supplied “blindly”, a spark is formed according to average parameters. This leads to:

  • 🚗 Failures during acceleration;
  • 🔥 Increased fuel consumption (up to +2–3 l/100 km);
  • 🛑 Refusal to start the engine (especially when “hot”).
⚠️ Attention: On Qashqai with engines HR16DE And MR20DE Trouble code P0335 is often accompanied by P0340 (phase sensor). This is due to the fact that the ECU uses the signals from both sensors for the correct operation of the variable valve timing system CVTC.

Reasons for error P0335

In 70% of cases, the crankshaft sensor itself is to blame, but ignoring other potential problems is dangerous. Here is a complete list of reasons for Nissan Qashqai:

Reason Frequency of occurrence Verification method
Crankshaft sensor malfunction (open, short) 65–70% Testing with a multimeter, replacing with a known good one
Damage to the wiring or DPKV connector 15–20% Visual inspection, checking ground and power circuit
Contamination or damage to the flywheel ring gear 10% Removing the engine protection, inspecting the crown (requires pit/lift)
ECU or firmware malfunction 3–5% Diagnostics with a scanner, flashing, unit replacement

Feature Qashqai: On models with automatic transmission, error P0335 may occur due to engine vibrations transmitted to the sensor through the bracket. In this case, installing an additional rubber gasket under the DPKV mount helps.

📊 What error did you encounter on your Nissan Qashqai?
  • P0335 (crankshaft sensor)
  • P0340 (phase sensor)
  • Other engine errors
  • No errors

Symptoms of a faulty crankshaft sensor

Error P0335 rarely appears “by itself” - it is usually preceded by noticeable changes in the behavior of the car. Here are the key signs for Nissan Qashqai:

  • 🚦 The engine stalls while driving and does not start for 2–3 minutes (especially after driving through puddles or washing);
  • 🔥 Floating speed at idle (from 500 to 1500 rpm);
  • ⚡ Power Loss when accelerating, “dullness” of the gas pedal;
  • 🛑 Startup failure after a short stop (“hot”).

Critical point: If Qashqai with engine MR20DE error P0335 is accompanied by a knocking sound in the timing belt area, stop operating immediately! This may indicate a shift in valve timing due to incorrect DPKV signals.

⚠️ Attention: On vehicles with Jatco CVT Ignoring P0335 will result in accelerated wear on the CVT belt. The transmission ECU receives distorted engine speed data and incorrectly adjusts the gear ratio.

How to Diagnose P0335 Without a Scanner

Not everyone has access to diagnostic equipment, but check the crankshaft sensor for Nissan Qashqai It is also possible with improvised means. Here are the step-by-step instructions:

1. Check the sensor power circuit (12V between pins 1 and 2 of the connector)

2. Inspect the flywheel ring gear for chips or contamination with metal shavings

3. Ring the sensor winding (the resistance between pins 2 and 3 should be 500–700 Ohms)

4. Check the engine ground (contact on the body next to the battery) -->

To check the sensor resistance:

  1. Remove the connector from the DPKV (located next to the oil filter on HR16DE or behind the generator at MR20DE).
  2. Connect the multimeter in ohmmeter mode to the contacts 2 and 3 (numbers are indicated on the connector body).
  3. Nominal resistance for Qashqai: 550–650 Ohm. A deviation of more than 10% is a reason for replacement.

If the resistance is normal, check the inductance (requires a megohmmeter or oscilloscope). To do this:

1. Подключите щупы к контактам 2 и 3.

2. Установите предел измерения 200 мГн.


3. Нормальное значение для ДПКВ Nissan: 200–400 мГн.

What to do if the sensor is working, but the error remains?

If the DPKV rings normally, but P0335 continues to appear, check:

- **Integrity of the shielding braid of the wiring** (often rubs against the exhaust manifold bracket).

- **The gap between the sensor and the ring gear** (should be 0.5–1.5 mm; as the gap increases, the signal weakens).

- **Supply voltage** on pin 1 of the connector (should be 12V when the ignition is on).

Replacing the crankshaft sensor on a Nissan Qashqai: step-by-step instructions

The procedure for replacing DPKV with Qashqai takes 20–30 minutes and does not require special tools. You will need:

  • 🔧 10 mm head;
  • 🔧 Extension or flexible cardan;
  • 🔧 Screwdriver with a flat blade (for removing the connector lock).

Algorithm of actions:

  1. Disconnect the negative terminal of the battery.
  2. Remove the plastic engine protection (4 x 10mm bolts).
  3. Find the sensor:
    • On HR16DE — to the right of the oil filter;
    • On MR20DE - behind the generator, below the box.
  • Press the connector lock and disconnect the wiring.
  • Unscrew the sensor mounting bolt (10 mm head) and remove it.
  • Install a new sensor (original part number: 23731-4M500 or 23731-4M505 for models after 2013).
    • ⚠️ Attention: When installing a new DPKV, do not use sealant on the bolt threads! Excessive tightening force may deform the sensor housing and distort the signal.
    💡

    Before purchasing a sensor, check it with a magnet: original DPKV for Qashqai should attract metal objects. Counterfeits are often made from non-magnetic alloys.

    Cost of repairs and selection of spare parts

    The cost of solving the P0335 problem depends on the cause and the chosen repair path:

    Type of work/spare parts Cost (RUB) Notes
    Crankshaft sensor (original) 2 500–3 800 Article: 23731-4M500/4M505. Suitable for all generations Qashqai.
    Crankshaft sensor (analog) 800–1 500 Recommended brands: Bosch, Febi, Blue Print.
    Diagnostics (scanner + circuit check) 1 000–1 500 Includes reading errors and checking wiring.
    Replacing the sensor in the service 800–1 200 Does not include the cost of spare parts.

    Saving tip: If error P0335 appears after a car wash or rain, try dry the DPKV connector hairdryer (temperature no higher than 60°C) and clean the contacts with alcohol. In 30% of cases this solves the problem without replacing the sensor.

    💡

    On Nissan Qashqai with a mileage of more than 150 thousand km, it is recommended to change the DPKV together with the oil filter and oil - this prevents metal shavings from getting on the flywheel ring gear.

    Common repair mistakes and how to avoid them

    Even experienced car owners make mistakes when troubleshooting P0335. That's what can't do on Qashqai:

    • 🔧 Use sensor from other models Nissan (for example, from X-Trail or Juke). Despite their external similarity, they have different sensitivities.
    • 🔧 Tighten the DPKV fastening bolt with a force of more than 8 Nm - this leads to deformation of the body.
    • 🔧 Ignore ring gear check. On engines MR20DE after 200 thousand km, the teeth often wear out or chip, which requires replacing the flywheel.

    Another common mistake is resetting the error without eliminating the cause. If you simply erase P0335 through the scanner, the ECU will return it after 10-20 km, and the problem will get worse. For example, ignoring a faulty DPKV on Qashqai with CVT can lead to failure of the box solenoids due to incorrect signals about engine speed.

    FAQ: Frequently asked questions about error P0335

    Is it possible to drive with P0335?

    Short term - yes, but not recommended. The engine will operate in emergency mode with increased fuel consumption and the risk of damage to the catalyst. On Qashqai with MR20DE Driving for a long time with P0335 can lead to overheating of the pistons due to incorrect ignition angle.

    Why does the error only appear when the engine is hot?

    This is a typical sign wiring faults or thermal damage to the sensor. When heated, the insulation of the wires may melt, causing a short circuit, or the DPKV itself may lose its performance characteristics. Check the power supply and ground with the engine running.

    Which crankshaft sensor is better to choose: original or analogue?

    Original sensor (Nissan 23731-4M500) more reliable, but an analogue from Bosch (article 0 261 210 115) shows similar results when installed correctly. The main thing is to avoid cheap Chinese counterfeits without a magnetic core.

    Could P0335 be caused by a faulty ECU?

    Yes, but extremely rarely (less than 5% of cases). This usually happens after unsuccessful chip tuning or moisture getting into the control unit. A problem with the ECU can only be diagnosed with a scanner capable of reading parameters in real time (for example, Launch X431).

    Is it necessary to reset the adaptations after replacing the DPKV?

    On Nissan Qashqai reset of adaptations is not required - the ECU will automatically “pick up” the new sensor after 2-3 startup cycles. However, if the error was accompanied P0340, it is recommended to reset the errors with a scanner and check the operation of the system CVTC.
