The crankshaft position sensor (CPS) is one of the most critical elements of the engine management system. Nissan X-Trail. Its failure leads to a complete stop of the motor or unstable operation, and diagnosis is often complicated by similar symptoms to other malfunctions. In this article we will look at how to accurately determine the problem with DPKV on X-Trail T31 (2007–2013) and T32 (2014–2021), what error codes indicate its failure, and how to replace it yourself without the risk of damaging the system.
Features of the crankshaft sensor Nissan with engines MR20DE, QR25DE And M9R (diesel) - its design and location. Unlike many competitors, here the DPKV is integrated with the drive disk, which requires careful dismantling. We will analyze original articles, analogues from Bosch And Denso, as well as typical installation errors that lead to repeated failure after 5–10 thousand km.
Symptoms of a faulty crankshaft sensor Nissan X-Trail
Symptoms of DPKV failure on X-Trail often disguised as problems with the fuel system or ignition. However, there are key signs that directly point to the sensor:
- 🚨 The engine stalls while driving and does not start (at the same time, the starter turns, but there are no flashes in the cylinders).
- ⚡ Lights up on the dashboard Check Engine with errors
P0335orP0336(DPKV circuits). - 🔄 Floating speed at idle (from 500 to 1500 rpm) for no apparent reason.
- 🛑 The engine starts only after several attempts, especially in wet weather.
- 📉 Power drop and jerking during acceleration (typical for diesel engines) M9R).
It is important to distinguish a malfunction of the DPKV from problems with the camshaft sensor (P0340). On X-Trail T32 with the system VVEL (variable valve lift) symptoms may overlap, but DPKV always gives errors along the circuit, and not through the signal. If the scanner shows P0335, but the engine starts - the problem is more likely in the wiring, and not in the sensor itself.
⚠️ Attention: On diesel X-Trail (M9R) a faulty DPKV can lead to damage to the injection pump due to incorrect angular position of the shaft. At the first sign of a malfunction, immediately turn off the engine and carry out diagnostics.
Error codes associated with DPKV on Nissan X-Trail
Modern scanners (for example, Launch X431 or Autel MaxiCOM) issue specific codes that help narrow down the troubleshooting area. For X-Trail The following errors are relevant:
| Error code | Description | Probable Cause | Actions |
|---|---|---|---|
P0335 |
DPKV circuit malfunction | Broken wiring, oxidation of contacts, short circuit | Ring the circuit, clean the connector, check the power (5V) |
P0336 |
Incorrect DPKV signal | Damage to the sensor, backlash of the drive disk, metal shavings on the magnet | Replacing the sensor, checking the gap (0.5–1.5 mm) |
P0327 |
Low signal level of DPKV | Contamination of the sensor, damage to the shielding braid | Cleaning, screen replacement, weight check |
P0328 |
High DPKV signal level | Short circuit at +12V, damage to the internal circuitry of the sensor | Replacing the sensor, checking the harness for chafing |
On Nissan X-Trail T31 with engine QR25DE error P0335 may appear when the battery charge is low (less than 11.5V). Before replacing the sensor, check the on-board voltage!
If the scanner shows several errors at the same time (for example, P0335 + P0300 - misfire), reset them first and see which one comes back first. Often P0300 - this is a consequence of an incorrect DPKV signal, and not an independent problem.

Where is the crankshaft sensor located on Nissan X-Trail?
The location of the DPKV depends on the generation and type of engine:
- 🔧 Gasoline
MR20DE/QR25DE(T31/T32): The sensor is installed on the oil pump cover, next to the crankshaft pulley. Access is possible from below (with removal of protection) or from above (when dismantling the intake manifold). - ⚙️ Diesel
M9R(T31): The DPKV is located on the cylinder block on the gearbox side, under the thermostat. Removal of the cooling system pipes is required.
On X-Trail T32 with MR20DD (direct injection) the sensor can be covered with a plastic cover - it must be carefully removed so as not to damage the latches. For the exact location, refer to the wiring harness running from the ECU to the front of the engine.
Connection diagram for DPKV on QR25DE
Sensor contacts:
1 - Ground (black wire)
2 - Signal (green/white)
3 - Power supply +5V (red/black)
Check the voltage between pins 1 and 3 with the ignition on - it should be 4.8–5.2V.
Master disk (reference) on Nissan made as part of the crankshaft pulley or flywheel (on diesel engines). When replacing the sensor, be sure to check the integrity of the disk teeth - chips or corrosion will lead to repeated errors.
How to check the crankshaft sensor for Nissan X-Trail?
Diagnosis of DPKV includes 3 stages: visual inspection, circuit check and signal testing. You will need a multimeter (with inductance measurement mode) and a metal object (screwdriver).
Remove the sensor and inspect for cracks/corrosion
Test the circuit for an open (coil resistance: 500–700 Ohms)
Check the gap between the sensor and the drive disk (0.5–1.5 mm)
Connect an oscilloscope or scanner to analyze the signal (amplitude ≥1V)-->
Step 1. Visual inspection
Remove the sensor (by unscrewing 1-2 10 mm bolts) and check:
- 🧲 Cleanliness of the magnetic core (sticky shavings distort the signal).
- 🔌 Integrity of the connector and wires (a common problem is chafing at the mount).
- 📏 Clearance to the master disk (on X-Trail should be 1±0.4 mm).
Step 2. Check with a multimeter
Switch the tester to ohmmeter mode and measure the resistance between the sensor terminals:
- Norm for Nissan: 550–750 Ohm (at 20°C).
- If the resistance is below 100 Ohms or above 1 kOhm, the sensor is faulty.
To check inductance (optional):
- Connect the probes to the sensor terminals.
- Bring a metal object (screwdriver) sharply to the core.
- A working sensor will show a voltage surge (0.3–1V).
⚠️ Attention: On diesel M9R The crankshaft sensor has a built-in signal amplifier. Its resistance is 800–1200 Ohms, and checking with an oscilloscope is mandatory - a multimeter will not detect a malfunction of the amplifier.
Replacing the crankshaft sensor with Nissan X-Trail: step by step instructions
To replace DPKV with X-Trail you will need:
- 🔧 10 mm head (for gasoline engines) or 12 mm (for diesel engines).
- 🧰 Extension cord and ratchet.
- 🧴 WD-40 or similar cleaner (bolts often stick).
- 📏 Feeler gauge for checking the gap (0.5–1 mm plate).
Sequence of actions:
- Disconnect the negative terminal of the battery.
- Disconnect the sensor connector (press the lock and pull up).
- Unscrew the mounting bolt (on a diesel engine, you may need to remove the thermostat).
- Carefully remove the sensor without damaging the O-ring.
- Clean the seat from dirt and oil.
- Install the new sensor, maintaining the gap (use a feeler gauge).
- Tighten the bolt to a torque of 8–12 Nm (do not overtighten!).
- Connect the battery connector and terminal.
After replacement be sure to reset the ECU adaptations via a diagnostic scanner (for example, with the command ECU Initialization in Launch). On X-Trail T32 with the system Start/Stop It may be necessary to calibrate the crankshaft position - it is better to entrust this procedure to a service center.
Before installing a new sensor, apply a thin layer of dielectric grease to the connector pins to prevent oxidation in high humidity environments.
Original articles and analogues of the crankshaft sensor for Nissan X-Trail
For X-Trail supplies original sensors Hitachi (Japan), but there are high-quality analogues on the market from Bosch, Denso And Febi. Below is the compatibility table:
| Engine model | Original article | Analogs (recommended) | Notes |
|---|---|---|---|
MR20DE (T31/T32) |
23731-4M51A |
Bosch 0 261 210 115, Denso 550-0103 | Comes with an O-ring |
QR25DE (T31) |
23731-AL51A |
Febi 27316, Blue Print ADG02731 | Often counterfeited - buy from authorized dealers |
M9R (diesel) |
23731-JK00A |
Hella 6PT 009 103-041, Valeo 586033 | Requires calibration after replacement |
The cost of the original sensor is from 3,500 to 6,000 rubles, analogues will cost 1,800–3,000 rubles. On X-Trail T32 with the system ProPILOT It is recommended to install only the original - analogues may give false alarms to the driver assistance system.
⚠️ Attention: When purchasing an analogue, check the markings on the sensor body. Counterfeits often lack the manufacturer's logo, and the rubber seal has uneven edges.
On diesel X-Trail after replacing the DPKV, be sure to perform the “Initializing the fuel system” procedure through the diagnostic scanner. Without it, the engine will run intermittently!
Common mistakes when replacing DPKV and how to avoid them
Even experienced craftsmen make mistakes that lead to repeated failure of the sensor. Here are the most common:
- 🔩 Fastening bolt tightening: Leads to deformation of the sensor body and a change in the gap. Tightening torque: no more than 12 Nm.
- 🧲 Ignoring metal shavings: If there were chips on the old sensor, its source (for example, a worn crankshaft bearing) must be eliminated.
- 🔌 Connector damage: When disconnecting, pull on the connector body, not the wires. On X-Trail T32 The connector is fragile and often breaks.
- 📏 Incorrect clearance: A gap of more than 1.5 mm leads to a weak signal, less than 0.5 mm leads to mechanical contact with the disk.
On petrol X-Trail After replacing the DPKV, it may be necessary to reset the throttle valve adaptations (procedure Throttle Valve Learning). If this is not done, the idle speed will be unstable for 1-2 days.
On diesel versions M9R A common mistake is forgetting to calibrate the crankshaft position after replacement. This leads to difficult startup and error P0336. Calibration is performed through the scanner service menu (for example, in Delphi DS150E).
FAQ: Frequently asked questions about the crankshaft sensor on Nissan X-Trail
Is it possible to drive with a faulty DPKV?
No. The crankshaft sensor is a critical element of the engine management system. If it fails, the engine will either not start or will operate with critical interruptions, which will lead to damage to the catalyst (on gasoline versions) or the injection pump (on diesels).
How to distinguish a faulty DPKV from a wiring problem?
If the scanner shows P0335, disconnect the sensor connector and check the resistance between pins 1 and 3 (power and ground). If the resistance is infinite, there is a break in the harness. If 0 Ohm - short circuit. Also inspect the wires for chafing near the exhaust manifold (a common place for damage).
Do I need to reset errors after replacing the sensor?
Yes, but not right away. After replacing, start the engine and let it run for 5-10 minutes. If the error does not appear again, you can reset it. If the error returns, the problem is not in the sensor (possibly in the ECU or wiring).
Is it possible to clean the crankshaft sensor instead of replacing it?
Cleaning is only possible if the problem is contamination of the magnetic core. Use a lint-free cloth and rubbing alcohol. However, if the sensor has cracks, traces of melting, or does not pass the test with a multimeter, replacement is required.
What other sensors can give similar symptoms?
Similar signs are given by:
- Camshaft sensor (P0340);
- Knock sensor (P0325);
- Throttle position sensor (P0120).
Diagnostics through a scanner will help to accurately identify the culprit.
