Crankshaft sensor on Nissan Qashqai: diagnostics, errors and DIY replacement

The crankshaft position sensor (CPS) is one of the key elements of the engine management system Nissan Qashqai (J10, J11). Its malfunction leads to malfunctions of the engine, difficult starting and even a complete stop of the car. Unlike many other sensors, DPKV does not have redundant systems, therefore its failure makes further operation of the machine impossible.

In this article we will look at how accurately determine the malfunction of the crankshaft sensor on Qashqai based on symptoms and error codes, what tools are needed for replacement, and why even the original sensor can fail after 50-80 thousand km. We will pay special attention to the nuances of diagnostics on gasoline engines. HR16DE, MR20DE and diesel K9K, where the verification algorithms differ.

Signs of a faulty crankshaft sensor on a Nissan Qashqai

The first symptoms of a problem with DPKV are often confused with malfunctions of the ignition system or fuel pump. However there is characteristic features, which directly point to the sensor:

• 🔴 Engine stalls while driving for no apparent reason, especially when suddenly releasing the gas or changing gears.
• 🔧 Starting the engine takes 5-10 seconds (the starter turns, but the engine does not “catch”).
• ⚡ Lights up on the dashboard Check Engine, but the scanner gives errors P0335, P0336 or P0339.
• 📉 Power drop and “failures” during acceleration, as if the engine is running on 2-3 cylinders.
• 🔄 Unstable idle speed (floats in the range of 500-1200 rpm).

On diesel Qashqai (engine K9K) a faulty DPKV may appear failure to start in cold weather below -15°C even if the battery is fully charged. Gasoline engines are more likely to suffer from detonation during acceleration - this is due to an incorrect ignition timing angle, which the ECU calculates based on the sensor signal.

⚠️ Attention: If on Qashqai with engine MR20DE light up at the same time Check Engine And ESP OFF, this may indicate an open circuit of the DPKV or damage to its connector. In this case, urgent diagnostics with a multimeter is required.

DPKV error codes and their interpretation

Modern versions Nissan Qashqai (2014+) support advanced diagnostics via OBD-II. Below are error codesproblems associated with the crankshaft sensor and their possible causes:

Error code	Description	Probable Cause	Recommendations
P0335	Crankshaft position sensor circuit malfunction	Wire break, contact oxidation, short circuit	Test the circuit with a multimeter and clean the connector.
P0336	DPKV signal range/performance out of normal range	Mechanical damage to the sensor, metal shavings on the magnet	Replace the sensor, check the condition of the flywheel
P0339	Unstable crankshaft sensor signal	Poor contact, damage to flywheel ring gear	Visual inspection of the flywheel, sensor replacement
P0340	Malfunction of the camshaft sensor circuit (indirectly related to the camshaft sensor)	Timing phase synchronization failure	Diagnose both sensors

On Qashqai J10 (2007-2013) error P0335 may appear due to bad sensor ground — its mount is located under the intake manifold and is often oxidized. On models with HR16DE often occurs false positive errors due to engine vibrations - in this case, replacing the sensor mount with a reinforced one helps.

Where is the crankshaft sensor located on a Nissan Qashqai?

The location of the DPKV depends on the engine type. On gasoline engines HR16DE And MR20DE sensor installed on the cylinder block next to the flywheel, on the gearbox side. On diesel K9K he is located on the clutch housing, just above the starter.

To get to the sensor:

1. Remove engine protection (on Qashqai J11 it is mounted with 4 bolts).
2. Disconnect negative terminal battery
3. On gasoline models, remove inlet pipe for ease of access.
4. The sensor is attached one 10 mm bolt and is secured with a latch connector.

On Qashqai with automatic transmission access to the DPKV is complicated due to the close location of the box. In this case it may be necessary jack or inspection holeto crawl underneath. On diesel versions, the sensor often gets stuck to the seat - do not try to pull it out by force, so as not to break the housing.

How to distinguish an original sensor from a fake?

The original DPKV for Qashqai (article 23731-4M010 or 23731-4M015) has:

- Nissan logo on body (engraved, not sticker).

- Metal core with a magnet (counterfeits are often plastic).

- Rubber sealing ring is black (counterfeit ones are red or gray).

- The connector is marked “JP” (Japan).

How to check the crankshaft sensor with a multimeter?

Diagnosis of DPCV on Nissan Qashqai includes verification winding resistance And induction voltage. You will need:

• 🔧 Multimeter with resistance (200 Ohm) and alternating voltage (200 mV) measurement modes.
• 🔹 Flat blade screwdriver (for removing the connector).
• 📏 Metal object (such as a wrench) for induction test.

Check procedure:

1. Measure resistance between the sensor contacts (standard for Qashqai: 550-750 Ohm). If the readings are lower 500 Ohm or higher 900 Ohm - the sensor is faulty.
2. Check induction:
   • Switch the multimeter to mode AC 200 mV.
   • Connect the probes to the sensor contacts.
   • Quickly pass a metal object in front of the core - a working sensor will show a voltage surge 0.3-1.0 V.

Ring the chain from the sensor to the ECU (contact 24 on the control unit connector). The resistance should be close to 0 ohm.

On Qashqai with diesel engine K9K additionally checked gap between sensor and flywheel (norm: 0.5-1.5 mm). If the gap is exceeded, the signal will be weak, resulting in an error P0336.

Step-by-step instructions for replacing the crankshaft sensor

Replacing DPKV with Nissan Qashqai takes 20-40 minutes depending on the engine type. It is important to follow the sequence of steps to avoid damaging the new sensor or connector.

Required tools:

• 🔧 10 mm head with extension.
• 🔹 Screwdriver with a Phillips bit (for removing protection).
• 🧲 Torque wrench (tightening torque: 8-12 Nm).
• 🧴 WD-40 (if the sensor is stuck).

Replacement algorithm:

1. Disable negative terminal battery
2. Remove the engine protection (on Qashqai J11 - 4 bolts of 10 mm).
3. Disconnect the sensor connector by pressing the latch.
4. Unscrew the mounting bolt and carefully remove the sensor. Don't pull the wires!
5. Clean the seat from dirt and metal shavings.
6. Install the new sensor, maintaining the gap. Tighten the bolt to torque 10 Nm.
7. Connect the connector and check for errors via OBD-II.

On diesel Qashqai may be required after replacement throttle valve relearning (procedure Throttle Valve Closed Position Learning). To do this:

1. Включите зажигание (не запуская двигатель).
2. В течение 5 секунд 5 раз полностью нажмите и отпустите педаль газа.
3. Подождите 7 секунд, затем нажмите педаль до упора и удерживайте 10 секунд.
4. Отпустите педаль и выключите зажигание.

Cost of sensor and replacement work

DPKV price for Nissan Qashqai varies depending on manufacturer and engine type. Below is a comparison table:

Manufacturer	Article	Price, rub.	Notes

Febi Bilstein	23731	1 800 — 2 300	Budget option, possible resource problems
Blue Print	ADT37301	2 000 — 2 500	Good price/quality ratio

Cost of replacement work in the service:

• 🔧 Gasoline engines: 800-1,500 rub.
• 🛢 Diesel engines: 1,500-2,500 rub. (difficult access).

On Qashqai with automatic transmission the price may be 30-50% higher due to the need to remove the box tray to access the sensor. If you decide to change the DPKV yourself, please note that low-quality analogue (for example, from NoName-manufacturers) can last less than 20 thousand km.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when working with DPKV on Nissan Qashqai. Here are the most common ones:

• ❌ Using sealant when installing the sensor. This causes silicone to get onto the core and false positives.
• ❌ Failure to maintain clearance between the sensor and the flywheel. On diesels K9K this causes an error P0336.
• ❌ Connector damage when disconnected. The contacts on the Qashqai are very fragile - pull on the housing, not the wires!
• ❌ Forgetting to reset errors after replacement. The ECU may continue to use old data, resulting in unstable operation.

On Qashqai J10 (2007-2013) common problem - shielded wire break sensor near the ECU connector. It can be restored by soldering, but it is better to replace the entire harness. On models with MR20DE after replacing DPKV it is sometimes required throttle adaptation, otherwise the idle speed will float.

⚠️ Attention: If after replacing the sensor the engine won't start at all, check the polarity of the connector. On Qashqai with diesel engine K9K mixed up contacts can damage the ECU.

FAQ: Frequently asked questions about the crankshaft sensor on Nissan Qashqai

Is it possible to drive with a faulty DPKV?

No. The crankshaft sensor is a critical element. If it fails, the engine will run unstably or will not start at all. On Qashqai with MR20DE Driving with a faulty DPKV can lead to catalyst overheating due to incorrect fuel mixture.

How often should the crankshaft sensor be replaced?

DPKV is a non-consumable element and is replaced only when it breaks. However, on Qashqai with a mileage of more than 150 thousand km It is recommended to check its condition every 30 thousand km, since wear of the flywheel or the ingress of metal shavings can reduce the life of the sensor.

Why doesn't the new sensor solve the problem?

Possible reasons:

• Damaged ring gear flywheel (replacement of flywheel required).
• Open or short circuit in wiring from the sensor to the ECU.
• Defective Engine ECU (on Qashqai J11 this occurs after unsuccessful firmware).
• Incorrect gap between the sensor and the flywheel (must be 0.5-1.5 mm).

What sensors can simulate a DPKV malfunction?

Similar symptoms are given by:

• 🔹 Camshaft sensor (error P0340).
• 🔹 Knock sensor (failures during acceleration).
• 🔹 Mass air flow sensor (MAF) (floating speed).
• 🔹 Ignition coils (on HR16DE/MR20DE).

Before replacing the DPKV, be sure to check these elements!

Is it possible to clean the crankshaft sensor?

Cleaning is only possible outside (remove dirt from the body). The core and winding cannot be cleaned - this will disrupt the calibration. If metal shavings are visible on the sensor, it should be definitely needs to be replaced, since metal particles damage the magnet.
