Crankshaft position sensor on Nissan Primera: diagnostics and repair

Crankshaft position sensor (DPKV) on Nissan Primera (especially models P11 And P12 with engines QR20DE, QR25DE, GA16DE) is a critical element of the engine management system. Its malfunction leads to engine malfunctions, difficult starting or a complete stop of the car. Unlike camshaft or knock sensors, DPKV does not have redundant systems, and its failure makes further operation of the machine impossible.

In this article we will look at how determine a sensor malfunction by indirect signs even before errors appear on the dashboard, what fault codes (P0335, P0336 etc.) indicate problems with the DPKV, and how to replace it yourself - with photographs and step-by-step instructions for Primera different generations. We will pay special attention to the selection of original and analog sensors, as well as typical installation errors that lead to repeated breakdowns.

How does the crankshaft position sensor work on a Nissan Primera?

DPKV on Nissan Primera refers to inductive type and records the passage of the teeth of the flywheel ring or crankshaft pulley. The signal from the sensor enters ECU (electronic control unit), which based on it calculates:

• 🔹 Fuel injection timing — exact time of opening of the injectors.
• 🔹 Ignition timing — when to apply a spark to the spark plugs.
• 🔹 Engine speed — to adjust the operation of systems in real time.
• 🔹 Piston position - to synchronize valve timing.

On Primera P12 (2002–2008) sensor located on oil pump housing on the crankshaft pulley side, next to the generator. On P11 (1996–2002) - similar, but access to it may be difficult due to the design of the engine compartment. Unlike camshaft sensors, DPKV has no moving parts, but is susceptible to contamination by metal shavings, vibration damage and broken wiring.

Signs of DPKV malfunction on Nissan Primera

Symptoms of a broken crankshaft sensor Primera can be divided into obvious (when the car won't start) and hidden (when problems appear periodically). The first include:

• 🚗 Engine won't start In general, the starter turns, but there is no spark and no injection.
• 🔋 Lights up on the dashboard Check Engine with errors P0335 ("Crankshaft Position Sensor Circuit") or P0336 ("Range/Performance of the DPKV circuit").
• 🛑 The car stalls immediately after launch or after a few seconds.

Hidden signs are often ignored, attributed to poor fuel or worn spark plugs:

• 🔄 Floating speed at idle (from 500 to 1500 rpm).
• 💨 Dips during acceleration - especially at rpm 2000–3000.
• 🔥 Detonation under load (a loud metallic knock).
• ⚡ Power Loss — the car is “stupid” as if it’s turned on ECO mode.

Feature Nissan Primera - in case of DPKV malfunction ECU may turn into emergency modeusing signals from the camshaft sensor. In this case, the engine will work, but with errors and increased fuel consumption (up to +2–3 l/100 km).

⚠️ Attention: If on Primera P12 with engine QR25DE after replacing the DPKV the car still does not start, check clearance between sensor and flywheel ring. He must be 0.5–1.5 mm. Exceeding this value results in a weak signal and repeated errors.

DPKV error codes and their interpretation

When scanning Nissan Primera using a diagnostic scanner (for example, Launch CReader or ELM327) DPKV malfunctions are manifested by the following codes:

Error code	Description	Probable Cause	Urgency of elimination
P0335	Crankshaft position sensor circuit	Wire break, contact oxidation, sensor damage	⭐⭐⭐⭐⭐ (critical)
P0336	DPKV circuit range/performance	Incorrect clearance, metal shavings on sensor, malfunction ECU	⭐⭐⭐⭐ (high)
P0337	Low signal level of the DPKV circuit	Sensor contamination, flywheel ring damaged	⭐⭐⭐ (medium)
P0338	High signal level of the DPKV circuit	Short circuit in wiring, malfunction ECU	⭐⭐⭐⭐ (high)
P0385	Crankshaft Position Sensor "B" Circuit	Synchronization error (rare, usually on V6 engines)	⭐⭐ (low)

On Primera P11 with engines GA16DE And SR20DE code P0335 may appear due to breakage of wire shielding, which goes from the sensor to ECU. Check the integrity of the wire visually and using a multimeter (the resistance between the central core and the braid should be endless).

What should I do if the scanner shows error P0335, but the sensor is working?

In 15% of cases the code P0335 on Nissan Primera arises due to:

1. **Poor contact in the connector ECU** - oxidation or deformation of the plugs (especially after washing the engine).

2. **Damage to the flywheel crown** - chipped or worn teeth (checked with an endoscope through the hole for the sensor).

3. **Faults ECU** - rare, but the unit may process the signal incorrectly. In this case, flashing or replacing the unit will help.

How to check the crankshaft position sensor on a Nissan Primera

Diagnosis of DPCV includes visual inspection, check resistance And oscilloscope. To get started, prepare your tools:

• 🔧 Multimeter (with resistance and voltage measurement mode).
• 🔍 Flashlight and magnifying glass for inspecting the connector.
• 📊 Oscilloscope (optional, for in-depth diagnostics).
• 🧲 Magnet (to check the sensor response).

Step 1. Visual inspection

Remove the sensor (by unscrewing the bolt on 10 mm) and check:

• 🔹 Hull integrity — cracks or chips are unacceptable.
• 🔹 Cleanliness of contacts - oxidation or green deposits indicate moisture ingress.
• 🔹 Presence of metal shavings at the end of the sensor (attracted by a magnet).

Step 2: Check Resistance

Connect the multimeter to the sensor terminals (polarity is not important). Normal resistance for Nissan Primera:

• 📊 500–700 Ohm - for sensors Hitachi (original).
• 📊 800–1000 Ohm - for analogues Bosch or Standard Motor Products.

If resistance 0 ohm (short circuit) or ∞ (break), the sensor must be replaced.

Remove the sensor from the car|Clean the contacts from oxidation|Measure the resistance between the terminals|Compare with the nominal (500–1000 Ohms)|Ring the wiring to the ECU-->

Step 3: Inductance Test (Optional)

To do this you will need a megohmmeter or an oscilloscope. Bring a metal object (for example, a screwdriver) to the end of the sensor - the resistance should be increase by 10–20%. If there is no change, the sensor is faulty.

⚠️ Attention: On Primera P12 with engine QR20DE After replacing the DPKV, be sure to reset the errors via the scanner. Otherwise ECU may continue to use incorrect data from memory, resulting in unstable engine operation.

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

The procedure for replacing DPKV with Primera takes 20–40 minutes and does not require special skills. You will need:

• 🔧 Head on 10 mm with extension cord.
• 🔨 Screwdriver with a flat blade (for removing the chip).
• 🧴WD-40 or Liqui Moly (if the bolt is stuck).
• 📏 Feeler gauge for checking the gap (optional).

Step 1. Preparation

Disable negative battery terminal and remove the engine protective cover (if equipped). On Primera P12 access to the sensor is more convenient from above, on P11 - from below (a lift or pit may be required).

Step 2. Removing the old sensor

1. Disconnect the connector by pressing the latch.
2. Unscrew the fastening bolt with the head on 10 mm.
3. Carefully remove the sensor by rocking it from side to side (do not force it!).

Step 3: Install a new sensor

Before installation:

• 🧹 Clean the seat from dirt and oil.
• 🔍 Check the integrity of the O-ring (included with the new sensor).
• 📏 Make sure that the gap between the end of the sensor and the flywheel crown is 0.5–1.5 mm (adjust with shims if necessary).

Step 4: Connection and testing

After installation:

1. Connect the connector until it clicks.
2. Connect the battery terminal.
3. Start the engine and check for errors with a scanner.

Sensor selection: original vs analogues

For Nissan Primera the original crankshaft position sensor has a part number 23731-4M000 (for P11) or 23731-AL50A (for P12 with QR20DE/QR25DE). Cost - from 3000 to 5000 rub. depending on the supplier. However, there are high-quality analogues on the market:

Manufacturer	Article	Compatibility	Notes
Hitachi	DK100	All models Primera	Original supplier for Nissan
Bosch	0 261 210 015	P11, P12 (except QR25DE)	Requires resistance testing before installation
Standard Motor Products	PC-406	P12 with QR20DE/QR25DE	Comes with an O-ring
Febi Bilstein	27396	P11 (engines GA16DE/SR20DE)	Budget option, but often defective copies

When choosing an analogue, pay attention to:

• 🔹 Resistance - must match the original (±10%).
• 🔹 Wire length - on P12 it's shorter than P11.
• 🔹 Availability of O-ring — without it, the sensor will quickly fail.

Typical mistakes when replacing DPKV and how to avoid them

Even experienced car owners make mistakes that lead to repeated breakdowns. Here are the most common:

• 🔧 Incorrect clearance — if the sensor is recessed too deeply or protrudes, the signal will be weak. Use the dipstick 0.5–1.5 mm.
• 🔌 Connector damage — when connecting the chip, do not pull the wires, but press the plastic case.
• 🧲 Ignoring metal shavings - if there were chips on the old sensor, check the oil pump and AVCS (variable valve timing system).
• 📉 Unreset errors - after replacement, be sure to delete fault codes with a scanner, otherwise ECU will work in emergency mode.

On Primera P11 with engine SR20DE a common problem broken wire near the connector. Before installing a new sensor, check the wiring from the chip to ECU (contact 24 on the block). There must be resistance 0 ohm.

⚠️ Attention: If after replacing DPKV with Primera P12 engine QR25DE works unstable, check valve timing. On these engines, a faulty DPKV can interfere with settings VTC (valve adjustment systems), which requires additional adaptation through Consult-III+.

FAQ: Frequently asked questions about DPKV on Nissan Primera

Is it possible to drive with a faulty crankshaft sensor?

No. Unlike the camshaft sensor, DPKV is a critical element. Without his signal ECU cannot determine the position of the crankshaft, which makes starting the engine impossible. In rare cases (on Primera P12 with QR25DE) the car can start in emergency mode, but will work intermittently and increase fuel consumption.

How to distinguish a malfunction of the DPKV from problems with the camshaft sensor?

Main differences:

• 🔹 In case of malfunction DPKV engine won't start at all or stalls immediately after starting.
• 🔹 In case of malfunction camshaft sensor (P0340) the car starts, but is unstable and may catch fire Check Engine.

Also on Primera with QR20DE/QR25DE when there are problems with the DPRV, the phases often go astray VTC, which is manifested by “floating” idle speed.

What happens if the sensor is installed incorrectly (for example, the sides are mixed up)?

Crankshaft position sensor on Nissan Primera asymmetrical — it can only be installed in one position. However, if you make mistakes:

• 🔹 Incorrect clearance (<0.5 mm or >1.5 mm) will result in a weak signal and an error P0336.
• 🔹 Damage to the O-ring will cause oil to enter the end of the sensor, which will lead to its rapid failure.
• 🔹 Misalignment during installation may cause mechanical damage to the housing.

How long does the crankshaft position sensor last on Primera?

Service life of the original sensor Hitachi — 150–200 thousand km. However, in practice it fails earlier due to:

• 🔹 Metal shavings in oil (worn crankshaft bearings or oil pump).
• 🔹 Vibrations - especially on engines QR25DE with faulty supports.
• 🔹 Moisture ingress into the connector (for example, after washing the engine).

On Primera P11 with mileage over 250 thousand km It is recommended to check the DPKV every 30 thousand km.

Is it possible to clean the crankshaft sensor if it is dirty?

Yes, but only if the problem is external pollution (oil, dirt). To clean:

1. Remove the sensor and clean it lint-free cloth, soaked in isopropyl alcohol.
2. Remove metal shavings from the end plastic scraper (do not use metal!).
3. Blow out the connector with compressed air.

If the sensor is dirty from the inside (for example, oil has penetrated under the housing), it needs to be replaced - cleaning will not help.
