Nissan crankshaft position sensor (CPS): pinout, testing and common errors

Crankshaft position sensor (DPKV) - one of the most critical elements of the engine control system in cars Nissan. The synchronization of fuel injection, ignition, and even the ability to start the engine depends on its correct operation. DPKV malfunctions are often disguised as other problems: from floating speed to complete engine failure. However, most car owners encounter difficulties already at the diagnostic stage - not knowing where is the sensor connector located?, how to correctly connect the multimeter probes and what values are considered normal.

In this article we will look at unique features of DPKV pinout on different Nissan models (including Qashqai, X-Trail, Almera And Note), we will show how connectors differ depending on the year of manufacture, and give step-by-step instructions for checking, taking into account typical diagnostic errors. We will pay special attention to common myths - for example, why replacing the sensor does not always solve the problem and when it is not the sensor that is to blame, but the wiring harness or the ECU.

Where is the DPKV located on Nissan: location and appearance

On most models Nissan The crankshaft position sensor is installed at the bottom of the cylinder block, next to the flywheel or generator drive pulley. The exact location depends on the engine type:

• 🔧 Gasoline engines HR16DE, MR20DE, QR25DE: The DPKV is attached to the oil filter housing or a bracket next to it. You need to look from the gearbox side, under the exhaust manifold.
• 🔧 Diesel K9K, YD25DDTi: the sensor is located on the flywheel cover (on the gearbox side), often covered with a protective cover.
• 🔧 Old models (GA16DE, SR20DE): The DPKV can be mounted in the camshaft housing (rarely) or next to it.

Externally, the sensor is a cylindrical body (diameter ~20–25 mm) with a 2 or 3 pin connector. It often bears the manufacturer's markings (Hitachi, Denso, Mitsubishi Electric). The main visual feature is that it sticks out from the body. core (rod) that fits closely to the ring gear of a flywheel or pulley.

⚠️ Attention: On diesel Nissan (For example, Navara with YD25) the sensor can be hidden under a heat shield. Before searching, remove the cover, otherwise you risk damaging the wiring!

To get to the DPKV, you usually need:

1. Remove the engine protection (if equipped).
2. Disconnect the sensor's power connector (the latch is often fragile - do not pull the wires!).
3. Unscrew the mounting bolt (usually 10 mm).

Nissan DPKV pinout: connection diagram by model

Structurally, the crankshaft position sensors are Nissan are divided into two types according to the number of contacts:

1. Two-pin (most common): used on most gasoline engines (Qashqai J10/J11, X-Trail T31/T32, Almera N16/N17).
2. Three-pin: found on diesel engines (Navara D40, Pathfinder R51) and some gasoline ones with a system Direct Injection.

Below is a pinout table for popular models:

Model Nissan	Engine type	Number of contacts	Pinout (wire color)	Purpose
Qashqai J10/J11	HR16DE, MR20DE	2	Black (+), Green (signal)	Black - ground, green - output signal to the ECU
X-Trail T31/T32	QR25DE	2	Brown (+), Blue (signal)	Brown - 5V power, blue - signal
Almera N16	QG15DE, QG18DE	2	White (+), Red (signal)	White - power, red - signal to the ECU
Navara D40	YD25DDTi	3	Black (ground), Red (+5V), Green (signal)	Three-wire sensor with shielding
Pathfinder R51	VQ25DE	2	Yellow (+), Black (signal)	Yellow - power, black - signal

It is important to consider that the colors of the wires may differ even within the same model - it all depends on the year of manufacture and configuration. For example, on Qashqai 2014+ with MR20DD Instead of a green signal wire, there may be a gray one.

⚠️ Attention: On diesel Nissan with a three-pin DPKV, the third wire (usually black) is screen, not mass. It must not be short-circuited to the housing during testing!

How to distinguish a two-pin sensor from a three-pin one?

Two-pin DPKVs usually have a plastic case with one latch on the connector, and three-pin ones have a metal screen and two latches. Also, three-pin sensors often have a "SHIELD" or "GND" marking next to the third pin.

How to check DPKV with a multimeter: step-by-step instructions

Diagnosis of the crankshaft position sensor includes three stages: checking winding resistance, supply voltage And signal when the engine rotates. To work you will need:

• 🔧 Multimeter (preferably digital with an AC voltage measurement function).
• 🔧 Screwdriver and 10 mm wrench for removing the sensor.
• 🔧 Two “crocodile” wires for connecting to the connector.

Verification algorithm:

1. Checking winding resistance:
   • Remove the sensor from the engine.
   • Connect the multimeter probes to the DPKV terminals (polarity is not important).
   • Set the resistance measurement mode (200–2000 Ohms).
   • Normal values: 550–750 Ohm for most models Nissan. On diesel engines (YD25) resistance can be higher - up to 1000 Ohms.
2. Checking the supply voltage:
   • Plug the connector back into the sensor.
   • Turn on the ignition (do not start the engine!).
   • Measure the voltage between + (nutrition) and weight. Must be 4.5–5.5 V.
3. Signal check:
   • Set the multimeter to alternating voltage (AC) mode.
   • Connect the probes to the signal wire and ground.
   • Crank the engine with the starter (an assistant is needed).
   • On a working sensor, the voltage should fluctuate in the range 0.3–1.0 V.

Clean the sensor from dirt (especially the core)|Check the integrity of the wires (for any fractures)|Disconnect the battery for 5 minutes to reset the ECU errors|Prepare a multimeter and wires for “ringing”-->

If the winding resistance is below 500 ohms or above 1000 ohms, the sensor is faulty. Lack of supply voltage (<5 V) indicates a wire break or ECU malfunction. A zero signal when the starter is cranked is a sign of a sensor failure or damage to the flywheel ring gear.

Typical DPKV errors: P0335 and P0336

Malfunction of the crankshaft position sensor in Nissan most often manifested by two error codes:

• 🚨 P0335 — "Crankshaft position sensor circuit." Indicates an open or short circuit in the DPKV circuit, as well as the absence of a signal.
• 🚨 P0336 — "Crankshaft Position Sensor Circuit Range/Performance." There is a signal, but it is unstable or beyond acceptable limits.

Reasons for these errors:

Error code	Possible reasons	How to fix
P0335	Broken power or signal wire. Oxidation of contacts in the connector. ECU malfunction (rare).	Ring the circuit, clean the contacts, replace the sensor.
P0336	Play or damage to the flywheel ring gear. Contamination of the sensor core with metal shavings. Incorrect clearance between sensor and flywheel.	Check the gap (0.5–1.5 mm), clean the sensor, replace the ring.

Important: error P0335 may appear occasionally, for example, during vibrations or after washing the engine. If the code disappears after a reset, the problem is most likely in the oxidized connector contacts.

⚠️ Attention: On Nissan Juke with engine HR16DE The P0336 code is often caused by a faulty wiring harness running near the exhaust manifold. Check the insulation - it may melt from high temperatures!

Replacing DPKV on Nissan: nuances and common mistakes

Replacing the crankshaft position sensor with Nissan This seems like a simple procedure, but there are a few critical points:

1. Gap between sensor and flywheel:

   Optimal distance - 0.5–1.5 mm. If the gap is larger, the signal will be weak; if less, there is a risk of core damage. On some models (for example, Navara D40) the gap is adjusted with washers.

2. Sensor marking:

   Even if the sensors look the same externally, they may differ in resistance and frequency response. For example, for Qashqai J11 with MR20DD Only the sensor with the article number is suitable 23731-4M01A, and the analogue from X-Trail T31 (23731-AL50A) will not work.

3. Tightening torque:

   The DPKV fastening bolt must be tightened with force 8–12 Nm. Tightening can deform the case, and weak tightening will lead to vibrations and false alarms.

Step-by-step replacement instructions:

1. Disconnect the negative terminal of the battery.
2. Disconnect the sensor connector (press the latch and pull to the side).
3. Unscrew the mounting bolt and remove the sensor.
4. Clean the seat from dirt and metal shavings.
5. Install the new sensor, maintaining the gap, and tighten the bolt.
6. Connect the connector and check for errors with a scanner.

Frequently asked questions about DPKV on Nissan

Is it possible to drive with P0335?

Technically possible, but highly not recommended. Trouble P0335 means that the ECU is not receiving a signal about the crankshaft position. This leads to:

• 🔴 Floating speed at idle.
• 🔴 Failures during acceleration.
• 🔴 Increased fuel consumption (up to 20–30%).
• 🔴 Risk of stopping the engine while driving.

On diesel Nissan (For example, Navara) Driving with P0335 may damage the fuel injection pump due to untimely injection.

How to distinguish the original DPKV from a fake?

Original sensors Nissan have the following characteristics:

• 🔍 Marking on the case: manufacturer’s logo (Hitachi, Denso) and article number (for example, 23731-4M01A).
• 🔍 The case is made of matte plastic (counterfeits are often glossy).
• 🔍 Magnetic alloy core (attracts metal objects).
• 🔍 Comes with a copper sealing washer.

Counterfeits are usually lighter in weight and have blurry markings. Their winding resistance often goes beyond 550–750 Ohms.

Why does the error not go away after replacing the DPKV?

If P0335/P0336 remains after installing a new sensor, check:

1. Integrity of the wiring from the sensor to the ECU (wires near the exhaust manifold often fray).
2. The gap between the sensor and the flywheel (should be 0.5–1.5 mm).
3. Condition of the flywheel ring gear (may be chipped or contaminated with metal shavings).
4. Supply voltage at the connector (should be 5 V when the ignition is on).
5. Condition of the ECU ground (often oxidizes on the body under the washer reservoir).

On Nissan Tiida with engine HR16DE A common problem is corrosion in the ECU connector (pin 37). Cleaning contacts solves the problem in 80% of cases.

Is it possible to clean the DPKV instead of replacing it?

Yes, but only if the problem is contamination of the core with metal shavings. To clean:

1. Remove the sensor and wipe the core with a lint-free cloth soaked in isopropyl alcohol (do not use acetone!).
2. Blow out the connector with compressed air.
3. Check the winding resistance - if it is normal, the sensor can be installed back.

If the core is chipped or corroded, the sensor must be replaced. Cleaning will not help with an internal winding break.

Alternative methods for diagnosing DPKV

If you don’t have a multimeter or scanner at hand, you can use alternative testing methods:

• 🔧 Visual inspection:
  • Check the integrity of the wires and connector (for melting or oxidation).
  • Make sure that the sensor core is not covered with metal shavings.
• 🔧 Checking with an oscilloscope (for advanced):
  • Connect the oscilloscope to the DPKV signal wire.
  • When scrolling the starter, the screen should display a smooth sine wave without gaps.
  • An uneven signal or missing teeth indicate a faulty sensor or flywheel ring.
• 🔧 Replacing with a known good one:
  • If it is possible to borrow a working sensor from the same engine, install it temporarily.
  • If the error disappears, your DPKV is faulty.

On Nissan Almera N16 with engine QG15DE You can check the DPKV “by ear”: if the sensor is faulty, the starter turns noticeably easier (no compression due to untimely injection). However, this method does not always work.

⚠️ Attention: On diesel Nissan (Navara, Pathfinder) an attempt to start with a faulty DPKV can lead to damage to the fuel injection pump due to chaotic fuel injection. Diagnose the sensor to multiple startup attempts!
