<em>Nissan AD</em> crankshaft sensor: diagnostics, errors and DIY replacement

Crankshaft position sensor (DPKV) - one of the most critical elements of the engine control system in cars Nissan AD. Its malfunction leads to engine malfunctions, difficult starting or complete engine stop. Unlike many other sensors, DPKV does not have redundant systems, so its failure makes further operation of the vehicle impossible.

Owners Nissan AD (especially with engines GA16DE, SR20DE, QR25DE) often encounter problems with this sensor after 150–200 thousand kilometers. In this article we will look at how diagnose the problem yourself, what Error codes (P0335, P0336) indicate a problem with the DPKV, and how to properly replace it without contacting service. We will also provide current prices for original and similar sensors for Nissan AD 2023–2026.

Symptoms of a faulty crankshaft sensor Nissan AD

The first symptoms of a breakdown DPKV often confused with fuel system or spark plug problems. However, there are a number unique features, which directly point to the sensor:

• 🔴 Engine won't start (the starter turns, but there are no flashes in the cylinders) - the most obvious sign, since without a signal from the DPKV, the ECU cannot determine the position of the crankshaft to supply a spark and fuel.
• 🟠 Floating speed at idle speed (from 500 to 1500 rpm) - the ECU loses the signal and tries to compensate for it using other sensors (for example, the camshaft).
• 🟡 Detonation during acceleration - incorrect ignition timing due to failures in the DPKV data.
• 🔵 Power Loss and “dips” when accelerating - the ECU goes into emergency mode, limiting the fuel supply.
• ⚠️ Check Engine lights up with errors P0335 or P0336 — direct fault codes for the DPKV circuit.

Feature Nissan AD - if the DPKV malfunctions, the engine may run "every other time": sometimes it starts normally, sometimes it takes several tries. This is due to the fact that the sensor periodically loses contact or produces an unstable signal. If you ignore the problem, over time the engine will stop starting altogether.

⚠️ Attention: On Nissan AD with automatic transmission (RE4F03A) a faulty DPKV can lead to transmission blocking in emergency mode. The automatic transmission ECU receives data on engine speed from the same sensor, and if it fails, the transmission stops shifting gears.

DPKV error codes and their interpretation for Nissan AD

When scanning Nissan AD using a diagnostic scanner (for example, Launch CReader or ELM327) the most common errors associated with the crankshaft sensor:

Error code	Description	Probable Cause	Criticality level
P0335	Crankshaft position sensor circuit malfunction	Wire break, contact oxidation, sensor damage	⭐⭐⭐⭐⭐ (critical)
P0336	DPKV circuit range/performance out of standard	Incorrect gap between sensor and drive disc, damage to disc teeth	⭐⭐⭐⭐ (high)
P0339	Intermittent crankshaft sensor signal	Poor contact in the connector, damage to the wire shielding	⭐⭐⭐ (average)
P0340	Malfunction of the camshaft sensor circuit (indirectly related to the camshaft sensor)	The ECU uses the camshaft signal to adjust the crankshaft data	⭐⭐ (low)

On Nissan AD with the system Nissan Consult errors may appear as hexadecimal codes (For example, 0335 instead of P0335). It is important to consider that P0335 And P0336 may also appear when mechanical damage to the drive disk (for example, chipped teeth or displacement relative to the sensor).

If the scanner shows P0335, but visually the sensor and wiring are ok, check:

• 🔧 Gap between sensor and disc (must be 0.5–1.5 mm).
• 🔍 Condition of teeth on the drive disk (there should be no chips or corrosion).
• 📶 Wire shielding — if the braid is damaged, interference from high-voltage wires can distort the signal.

Where is the crankshaft sensor located on Nissan AD?

Most models Nissan AD (including Wingroad, Bluebird Sylphy, AD Van/Respect) DPKV installed on the cylinder block near the flywheel or crankshaft pulley. The exact location depends on the engine type:

• 🔹 Engines GA16DE/SR20DE — the sensor is located to the right of the block (in the direction of travel), next to the gearbox. approaches him two-pin connector with black and white wire.
• 🔹 Engines QR25DE — the sensor is located on the front of the block, closer to the generator. The connector is three-pin (additional contact for shielding).
• 🔹 Diesel CD20 — sensor installed on the flywheel cover, access to it is difficult (removal of the starter is required).

To find the sensor, focus on:

1. Master disk - a metal disk with teeth that is attached to the crankshaft.
2. Shielded wire - usually black or gray, goes to the ECU.
3. Single bolt mounting (less often - on two) with a turnkey head 10 mm.

The photo below shows a typical location of the DPKV on Nissan AD with engine SR20DE:

The image shows a sensor (indicated by a red arrow) next to the gearbox. The connector is connected to a wiring harness that runs along the cylinder block. The master disk (blue arrow) has 60 teeth, two of which are missing for synchronization.

⚠️ Attention: On Nissan AD with gas equipment (GBO) crankshaft sensor may fail more often due to increased vibrations when running on gas. It is recommended to check its condition every 30–40 thousand km.

How to check the crankshaft sensor for Nissan AD?

Diagnosis of DPCV can be performed three ways: visually, with a multimeter and an oscilloscope. For most owners Nissan AD The first two methods are sufficient.

1. Visual inspection

Check:

• 🔌 Connector status — is there any oxidation, burnt contacts or traces of moisture.
• 🧲 Wire integrity — the shielding braid must not be torn.
• 🔩 Sensor mount — the bolt should not be loosened (vibrations distort the signal).
• 🦷 Master disk — the teeth must not be chipped or corroded.

2. Check with a multimeter

To test resistance and voltage:

1. Remove the connector from the sensor.
2. Set the multimeter to mode resistance measurements (2000 Ohm).
3. Connect the probes to the sensor contacts:
   • Normal resistance for Nissan AD: 500–700 Ohm.
   • If the readings 0 ohm - short circuit if ∞ - break.
4. Check supply voltage (with ignition on):
   • Between the "+" of the sensor and ground there should be 4.5–5.5 V.

3. Checking with an oscilloscope (for advanced)

If you have access to an oscilloscope (or USB auto scanner with oscilloscope function), connect it to the signal wire of the sensor. When cranking with the starter, it should display stable sine wave no gaps. Irregular peaks or signal dropouts indicate a malfunction.

Step-by-step instructions for replacing the crankshaft sensor with Nissan AD

Replacing DPKV with Nissan AD takes 20–40 minutes and does not require special tools. You will need:

• 🔧 Key on 10 mm (or head with extension).
• 🔩 Screwdriver with a flat blade (for removing the connector).
• 🧴WD-40 or PB Blaster (if the bolt is soured).
• 📦 New sensor (original or analogue, see table below).

Sequence of actions:

1. Disconnect the battery (remove the negative terminal) to avoid short circuit.
2. Find the sensor (see section above) and clean it of dirt.
3. Disconnect the connectorby pressing the latch (do not pull the wires!).
4. Unscrew the fastening bolt key on 10 mm. If the bolt does not budge, treat it with WD-40 and wait 5-10 minutes.
5. Remove the sensor, gently rocking it from side to side (do not use force so as not to break the body!).
6. Install a new sensor, aligning it with the seat. Tighten the bolt to torque 8–10 Nm.
7. Connect the connector and check the reliability of fixation.
8. Connect the battery and start the engine. If the error P0335 disappeared - the replacement was successful.

⚠️ Attention: On Nissan AD with engine QR25DE when replacing DPKV be sure to check the gap between the sensor and the drive disk. He must be 1.0 ± 0.2 mm. If the gap is larger, the signal will be weak; if less, the sensor may touch the disk.

After replacement, reset errors using a scanner or by disconnecting the battery at 10–15 minutes. If Check Engine lit up again, check:

• 🔌 The connector is connected correctly.
• 🔧 Quality of bolt tightening (under-tightening leads to vibrations).
• 🛠️ Condition of the master disk (may need replacement).

Common mistakes when replacing DPKV and how to avoid them

Even experienced car owners make mistakes when replacing the crankshaft sensor with Nissan AD. Here are the most common of them:

1. Using the wrong sensor:

   On Nissan AD with SR20DE And QR25DE The sensors are similar in appearance, but have different resistance. Installing an incorrect sensor will result in an error P0336.

2. Incorrect clearance:

   If the sensor is installed too close to the disc (<0.5 mm), it can touch the teeth and fail. If it's too far (>1.5 mm) - the signal will be weak.

3. Damage to the wire during installation:

   When connecting the connector, the wire at the base of the sensor is often broken. Always hold the connector body, not the cable.

4. Ignoring master disk status:

   If the disk has chipped teeth or is corroded, the new sensor will not last long. In severe cases, disc replacement is required (to Nissan AD This is a labor-intensive operation, since you need to remove the flywheel).

5. Unreset ECU errors:

   After replacing the sensor, be sure to clear the errors using a scanner or disconnecting the battery. Otherwise, the ECU will operate in emergency mode.

⚠️ Attention: On Nissan AD with immobilizer system NAT after replacing the DPKV it may be necessary retraining keys. If the engine does not start and the immobilizer icon is flashing on the dashboard, contact your diagnostician for synchronization.

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

Is it possible to drive with a faulty DPKV?

No. The crankshaft sensor is a critical element of the engine management system. Without its signal, the ECU cannot determine the position of the crankshaft, so the engine will either not start or will run intermittently. Driving for a long time with a faulty DPKV can lead to damage to the catalyst due to incorrect fuel mixture.

Which sensor is better to choose: original or analogue?

For Nissan AD recommended original sensor Nissan or Hitachi, since they have better protection against vibrations and temperature changes. Analogues (Bosch, Denso) are suitable for temporary replacement, but their service life is limited 20–30% below. Cheap sensors (ERA, Febi) often fail through 10–20 thousand km.

Why is there an error after replacing the DPKV? P0335 doesn't disappear?

There are several reasons:

• 🔌 Incorrect connector connection (contacts are mixed up).
• 🔧 Failure to maintain the gap between the sensor and the disk.
• 🛠️ Damage to the master disk (replacement required).
• 📶 Break or short circuit in the wiring (check with a multimeter).
• 🖥️ ECU malfunction (rare, but possible).

Check all the points in order. If the problem persists, contact a diagnostician to check with an oscilloscope.

How long does the crankshaft sensor last? Nissan AD?

Service life of the original DPKV - 150–250 thousand km. However, in practice it may fail earlier due to:

• 💦 Moisture gets into the connector.
• 🔥 Engine overheating (even once).
• 🛠️ Mechanical damage during repairs.
• ⚡ Electrical interference from high-voltage wires.

On diesel Nissan AD (CD20) the sensor lasts longer due to less vibration.

Is it possible to clean the crankshaft sensor instead of replacing it?

Cleaning is possible only in one case - if the sensor contact oxidation. To do this:

1. Remove the sensor and clean the contacts alcohol solution.
2. Blow out the connector with compressed air.
3. Apply to contacts dielectric grease (For example, Liqui Moly Electronic-Spray).

If the problem is sensitive element (for example, a broken winding), cleaning will not help - replacement is required.
