Error P0340 on Nissan Qashqai - one of the most common problems associated with the engine management system. It indicates a fault in the circuit camshaft position sensor (CPR), which is responsible for synchronizing the operation of the fuel system and ignition. If you ignore this code, the consequences can range from increased fuel consumption to complete engine shutdown.

Owners Qashqai (especially models with engines HR16DE, MR20DE And M9R) often encounter this error after 100-150 thousand kilometers. The reason may lie in the sensor itself, or in the wiring, connectors, or even mechanical damage to the gas distribution mechanism. In this article we will look at all possible causes of P0340, diagnostic and repair methods, and we will also give recommendations on how to avoid the recurrence of the error.

What does error P0340 mean on Nissan Qashqai

Code P0340 stands for "No Camshaft Position Sensor Signal" — there is no signal from the camshaft position sensor. This sensor (also known as DPRV or CMP sensor) transmits data to ECU about the current position of the camshaft, which is necessary for:

  • 🔥 Precise fuel injection into the cylinders.
  • ⚡ Correct ignition timing.
  • 🔄 Synchronization of the crankshaft and camshaft.
  • 🚗 Optimal operation of the variable valve timing system (VVT).

When the signal from the sensor disappears or becomes unstable, the ECU goes into emergency mode, using data only from the crankshaft sensor (DPKV). This leads to:

  • ⚠️ Sunbathing Check Engine on the dashboard.
  • 🐢 Loss of power and dullness of the engine.
  • ⛽ Increased fuel consumption (up to 10-15%).
  • 🔊 Uneven engine operation at idle speed.

On Nissan Qashqai with diesel engines (M9R) error P0340 may also be accompanied by difficulty starting hot or stopping the engine completely while driving.

📊 How often do you encounter engine errors on your Qashqai?
  • Regularly (once a month or more often)
  • Sometimes (every six months)
  • Nearby (1-2 times during the entire period of ownership)
  • Never

The main causes of the P0340 error code

Reasons for the appearance P0340 on Nissan Qashqai maybe several. They are conventionally divided into electric (problems with wiring, connectors, sensor) and mechanical (timing timing, camshaft faults). Let's look at each category in more detail.

1. Malfunction of the camshaft position sensor (CPR)

The most common reason is failure of the sensor itself. On Qashqai sensors are installed inductive or Hall's type (depending on year of manufacture). Signs of malfunction:

  • 🔌 Short circuit or break inside the sensor.
  • 🧲 Loss of magnetic properties of the core (for inductive sensors).
  • 🔥 Overheating or mechanical damage to the case.

Service life of DPRV for Nissan usually amounts to 80-120 thousand km, but with aggressive driving or poor operating conditions (dust, moisture), it may fail earlier.

2. Problems with wiring and connectors

Often a mistake P0340 arises due to:

  • 🔌 Oxidation or corrosion of contacts in the sensor connector.
  • 🔥 Chafing or breaking of wires (especially near the exhaust manifold).
  • 💧 Moisture getting into the connector (relevant for cars with mileage >150 thousand km).

On Qashqai with engine MR20DE DPRV wires often rub against the intake manifold bracket. This leads to periodic signal loss and the appearance of an error.

3. Mechanical timing faults

If the sensor and wiring are ok, the problem may lie in:

  • 🔗 Stretching or slipping of the timing chain/belt.
  • 🛠️ Wear of the camshaft sprocket (especially on engines HR16DE after 200 thousand km).
  • 🔧 Incorrect installation of timing marks after repair.

On diesel Qashqai (M9R), error P0340 is often accompanied by code P0016 (camshaft and crankshaft timing mismatch), which directly indicates problems with the timing chain.

4. ECU or firmware malfunctions

Less commonly, the reason lies in:

  • 🖥️ ECU firmware failure (relevant after “handicraft” chip tuning).
  • 🔌 Damage to the tracks of the control unit board.
  • 🔋 Unstable power supply to the ECU (problems with relays or fuses).

On Qashqai 2014-2017 model years there were cases when the error P0340 appeared after updating the ECU firmware via a dealer scanner. In this case, rolling back to the previous version of the software helps.

💡

Before replacing the DPRV, check the timing chain for tension! On a Qashqai with a mileage of >150 thousand km, the chain may “go off” by 1-2 teeth, which will lead to the reappearance of P0340 even after replacing the sensor.

How to Diagnose the P0340 Code

Diagnostics P0340 on Nissan Qashqai includes checking the sensor, wiring and mechanical components. Below are step-by-step instructions that you can perform yourself or in the service.

1. Reading errors with a scanner

The first step is to connect a diagnostic scanner (for example, ELM327, Launch CReader or dealer Consult III+) and:

  • 📋 Record all active and historical errors (especially P0340, P0341, P0016).
  • 📊 View camshaft sensor parameters in real time (CMP Sensor Signal).
  • 🔍 Check for related errors (for example, P0335 - DPKV malfunction).

If the signal from the DPRV is completely absent (0 V), the problem is most likely in the sensor or wiring. If there is a signal, but it is unstable, check the mechanics.

2. Checking the camshaft position sensor

To test the DPRV you will need a multimeter. Verification algorithm:

  1. 🔧 Remove the sensor (it is located on the cylinder head, next to the camshaft).
  2. 🔌 Check the resistance between the contacts:
    • For inductive sensors: norm - 500-1500 Ohm.
    • For Hall sensors: Resistance may be infinite (need to check power supply).
  • 🔋 Check the supply voltage (should be 5 V or 12 V, depending on the type of sensor).

    • If the resistance or voltage is not normal, the sensor must be replaced. On Qashqai the original DPRV has an article number 23731-4M000 (for gasoline engines) or 23731-ED000 (for diesel engines).

    3. Checking wiring and connectors

    Breaks or short circuits in the DPRV circuit are the second most common cause P0340. What to do:

    • 🔍 Inspect the sensor connector for corrosion, moisture or damaged contacts.
    • 🔌 Call the wires from the sensor to the ECU (the connection diagram is in the repair manual).
    • 🛠️ Check the “ground” of the sensor - it often oxidizes or comes off.

    On Qashqai with engine HR16DE The DPRV wires run close to the exhaust manifold and may melt. In this case, the harness needs to be replaced.

    4. Check mechanical components

    If the sensor and wiring are OK, but the error remains, check:

    • 🔗 Timing chain: for sprocket stretching, slipping or wear.
    • 🔧 Timing marks: do they match after repair?
    • 🛠️ Camshaft: is there any play or mechanical damage.

    On diesel Qashqai (M9R) the timing chain can stretch to 150 thousand km, which leads to phase failure and error P0340.

    Reason Symptoms Verification method
    Faulty DPRV No signal, constant error Testing with a multimeter
    Broken wiring The error appears periodically Chain continuity check, harness inspection
    Stretched timing chain Error + P0016, operating noise Visual inspection, backlash measurement
    Connector oxidation Error after rain or car wash Cleaning contacts, treating with WD-40
    💡

    If on a Qashqai with an M9R diesel engine the P0340 error is accompanied by a P0016 code, in 90% of cases the problem is a stretched timing chain. Replacing the chain and sprockets solves the problem.

    How to Troubleshoot P0340: Step-by-Step Instructions

    The repair method depends on the cause of the problem. Below are instructions for the most common cases.

    1. Replacing the camshaft position sensor

    If the DPRV is faulty, it must be replaced. To do this:

    1. 🔧 Disconnect the negative terminal of the battery.
    2. 🔍 Find the sensor on the head of the block (usually it is secured with one 10mm bolt).
    3. 🔌 Disconnect the connector and unscrew the sensor.
    4. 🆕 Install a new sensor (original or analogue, for example, Bosch 0 261 210 115).
    5. 🔧 Tighten the bolt to torque 8-10 Nm.
    6. 🔋 Connect the battery and reset the errors with the scanner.

    After replacing, start the engine and check if the error disappears. If not, look for a problem in the wiring or mechanics.

    2. Wiring repair

    If the reason is in the wires:

    • 🔍 Find the place where there is a break or chafing (most often near the exhaust manifold).
    • 🛠️ Clean and insulate the damaged area or replace the entire tourniquet.
    • 🔌 Treat the connector contacts with a special lubricant (for example, Liqui Moly Kontakt-Spray).

    On Qashqai with engine MR20DE The harness near the intake manifold often frays. In this case, it is recommended to lay the wires in corrugation for protection.

    3. Replacing the timing chain

    If the problem is a stretched chain:

    1. 🔧 Remove the timing cover (a special tool is required to fix the shafts).
    2. 🔗 Check the chain tension and the condition of the sprockets.
    3. 🆕 Replace the chain, tensioner and sprockets (kit for M9R has an article number 13028-4M50A).
    4. 🔧 Set the timing marks according to the manual.

    Attention! On diesel Qashqai Replacing the timing chain requires a special tool to lock the crankshaft and camshafts. Without it, there is a risk of losing phases.

    4. Error reset and adaptation

    After repair:

    • 🔧 Connect the scanner and clear all errors.
    • 🔄 Perform throttle adaptation (if required).
    • 🚗 Drive 20-30 km and check if the error returns.

    On some Qashqai after replacing the DPRV is required ECU retraining (procedure ECU Relearn), otherwise the error may appear again.

    What to do if after replacing the DPRV the error remains?

    If a new sensor is installed but P0340 does not go away, check:

    1. The connector is connected correctly (are the contacts reversed).

    2. Integrity of the signal wire from the sensor to the ECU.

    3. Availability of supply voltage (5 V or 12 V, depending on the sensor model).

    4. Condition of the sensor ground (often oxidizes on the body).

    If everything is in order, but the error remains, the problem may be in the ECU or firmware.

    Cost of repairs and selection of spare parts

    The cost of repair depends on the cause of the error P0340 and region. Below are indicative prices for Nissan Qashqai (for 2026).

    Type of repair Cost of spare parts (₽) Cost of work (₽) Total (₽)
    Replacing DPRV (original) 3 500 – 5 000 800 – 1 500 4 300 – 6 500

    To save money, you can buy analogues of original spare parts:

    • 🔧 DPRV: Bosch 0 261 210 115 (~2,000 ₽) or Febi 27300 (~1 500 ₽).
    • 🔗 Timing kit: Gates K015631XS (~10,000 ₽) or Contitech CT1135K1 (~9 500 ₽).

    Attention! On Qashqai with diesel engine M9R It is not recommended to install cheap timing chains - they can stretch after 50 thousand km.

    Prevention of error P0340 on Nissan Qashqai

    To avoid reappearance P0340, follow these guidelines:

    • 🔧 Regularly (every 10-15 thousand km) clean the DPRV contacts from oxidation.
    • 🛠️ Check the condition of the timing chain every 100 thousand km (on diesel engines - every 80 thousand km).
    • 💧 Avoid washing the engine under high pressure - water may get into the sensor connector.
    • 🔋 Monitor the voltage of the on-board network (it should be 13.8-14.4 V), since jumps can damage the DPRV.

    On petrol Qashqai with engine HR16DE It is recommended to check the timing chain tension once every 60 thousand km, even if there are no signs of malfunction. This will help avoid stretching and phase failure.

    For diesel versions (M9R) critical to use quality oil (For example, Mobil 1 ESP 5W-30 or Liqui Moly Top Tec 4200), as poor lubrication accelerates wear on the chain and sprockets.

    💡

    On a Qashqai with a mileage of >150 thousand km, the timing chain is a “ticking time bomb”. Even if the P0340 error has not yet appeared, check its condition to avoid engine failure and major repairs.

    Frequently asked questions about error P0340 on Nissan Qashqai

    Is it possible to drive with P0340?

    Short term - yes, but not recommended. The engine will operate in emergency mode, which will lead to:

    • ⛽ Increased fuel consumption (up to 15%).
    • 🐢 Loss of power and jerking during acceleration.
    • 🔥 Risk of damage to the catalyst due to incorrect fuel mixture.

    On diesel Qashqai riding with P0340 may lead to damage to fuel equipment (injectors, injection pump).

    Why does P0340 appear after washing the engine?

    Most likely, water got into the DPRV connector or onto the ECU contacts. What to do:

    1. 🔧 Dry the connector with a hairdryer or compressed air.
    2. 🔌 Process your contacts WD-40 or special lubricant.
    3. 🚗 Ride 10-15 km - if the error does not disappear, check the sensor with a multimeter.

    If the problem persists, replace the connector or seal it with silicone grease.

    What sensors can affect P0340?

    In addition to the DPRV, on the appearance P0340 may influence:

    • 🔍 Crankshaft sensor (CPCV) - if it is faulty, the ECU cannot synchronize the signals.
    • 🔧 Coolant temperature sensor — incorrect data can throw off fuel maps.
    • ⚡ Knock sensor - indirectly affects the ignition timing.

    If together with P0340 errors are on P0335 (DPKV) or P0115 (temperature sensor), eliminate them first.

    Can bad fuel cause P0340?

    No, P0340 This is a purely electrical or mechanical fault. However, bad fuel can:

    • 🛢️ Clog the injectors, which will lead to errors in the fuel system (P0200-P0204).
    • 🔥 Cause detonation that will damage the DPRV or DPKV.

    If the error appears after refueling, check knock sensor (P0325-P0332).

    Is it necessary to do adaptation after replacing the DPRV?

    On most Nissan Qashqai no adaptation required, but:

    • 🔧 On models with VVT system (For example, MR20DE) adaptive values may need to be reset.
    • 🖥️ If the error remains after replacement, try resetting the ECU (remove the battery terminal for 10 minutes).
    • 🚗 On diesel versions (M9R) sometimes required fuel injection pump retraining.
