Nissan Primera P12 (2002-2008) is a reliable sedan, but even it has its weaknesses. One of them is Crankshaft position sensor (CPS), whose malfunction can immobilize the car at the most inopportune moment. This sensor synchronizes the operation of the ignition and fuel injection systems, and its failure is often disguised as other problems: from bad gasoline to faulty spark plugs.

In this article we will look at how accurate diagnosis helps to distinguish the breakdown of the DPKV from similar symptoms, which unique errors (P0335, P0336) are issued by the ECU Primera P12 when it fails, and why replacing the sensor with a non-original analogue can lead to a repeated failure after 10–15 thousand km. We will also provide step-by-step instructions with photos on how to dismantle and install a new sensor without removing the crankcase protection - this will save you 1-1.5 hours of work.

Symptoms of a faulty crankshaft sensor Nissan Primera P12

Symptoms of DPKV failure on Primera P12 often confused with fuel system or ignition problems. The main difference is instability of symptoms: today the car won’t start, tomorrow it drives normally, and the day after tomorrow it stalls while driving. Here are the key signs:

  • 🔴 Engine won't start (the starter turns, but there is no spark and no fuel injection). This is a 100% sign of failure of the DPKV - the ECU does not receive a signal about the crankshaft position and blocks the operation of the system.
  • ⚡ Misfires at idle or under load, especially in wet weather (condensation penetrates the sensor connector).
  • 📉 Power drop and jerks during acceleration - the ECU goes into emergency mode, using average data instead of accurate DPKV readings.
  • 🚨 Check Engine with errors P0335 (“Crankshaft sensor circuit”) or P0336 (“Invalid DPKV signal”). On Primera P12 These codes almost always indicate a physical problem with the sensor rather than a wiring problem.

Feature Primera P12: with a faulty DPKV engine QR20DE or QR25DE may start “every time” - this is due to the fact that the ECU is trying to use the signal from the camshaft sensor for an emergency start. However, driving in this mode accelerates wear of the catalyst and lambda probes.

⚠️ Attention: If after washing the engine or rain the car becomes difficult to start, first check DPKV connector for the presence of oxidation. On Primera P12 it is located at the bottom of the cylinder block and often becomes clogged with dirt.

Where is the crankshaft sensor located on Nissan Primera P12?

On Primera P12 with engines QR20DE And QR25DE crankshaft sensor installed in bottom of cylinder block, next to the flywheel. Exact location:

  • 📍 To the right of the oil filter (if you look in the direction the car is moving).
  • 🔧 Under crankcase protection — to gain access you will have to remove the plastic shield (4 bolts x 10 mm).
  • 🔌 Connector facing up, which makes it easier to disconnect, but increases the risk of moisture ingress.

The photo below shows the location of the sensor (red arrow) relative to the flywheel (blue arrow):

Visually DPKV Primera P12 is a small cylinder with a diameter of ~25 mm with a plastic connector and a metal core. Fastened with one 10 mm bolt. Don't confuse it with the knock sensor, which is located higher on the cylinder block!

📊 How often do you check engine sensors?
  • Only when errors occur
  • Once a year during maintenance
  • Never checked
  • I diagnose myself every 3-6 months.

How to check the crankshaft sensor for Nissan Primera P12 multimeter?

Diagnosing CPPV takes 10–15 minutes and requires only a multimeter. Procedure:

  1. Removing the sensor:
    • Disconnect the connector (press the latch and pull up).
    • Unscrew the fastening bolt (10 mm wrench).
    • Carefully remove the sensor - do not damage the O-ring!
  • Resistance test:

    Connect a multimeter in ohmmeter mode to the sensor terminals. Normal resistance for Primera P12: 550–750 Ohm. If the readings are below 400 Ohms or above 900 Ohms, the sensor is faulty.

  • Inductance test (optional):

    For accurate diagnostics, use a megohmmeter or oscilloscope. The inductance must be within 200–400 mH. If the winding is broken or there is an interturn short circuit, the readings will be close to zero.

    • If the sensor is working, but there is an error P0335 remains, check:

    • 🔌 Wiring integrity from the sensor to the ECU (wires near the exhaust manifold often fray).
    • 🧲 Gap between sensor and flywheel - must be 0.5–1.5 mm. As the gap increases, the signal weakens.
    • 💧 No metal shavings on the sensor core (indicates flywheel wear).

    ☑️Diagnostics of DPKV on Primera P12

    Done: 0 / 5
    ⚠️ Attention: On Primera P12 with an automatic transmission, if the DPKV is faulty, gear shifting may be blocked - the gearbox ECU receives a signal from the engine ECU about abnormal operation. If the problem remains after replacing the sensor, reset the automatic transmission adaptations via CONSULT-III or similar scanner.

    Errors P0335 and P0336: what do they mean and how to fix them?

    On Nissan Primera P12 errors associated with DPKV have specific causes:

    Error code Description Probable Cause Solution
    P0335 Crankshaft position sensor circuit malfunction
    • Break or short circuit in the wiring
    • Oxidation of connector contacts
    • ECU malfunction (less common)
    1. Ring the wiring
    2. Clean connector contacts
    3. Check sensor power supply (12 V)
    P0336 Incorrect crankshaft position sensor signal
    • The sensor itself is faulty
    • Displacement or damage to the drive disc on the flywheel
    • Metal shavings on the sensor core
    1. Replace sensor
    2. Check the gap (0.5–1.5 mm)
    3. Inspect the flywheel for damage
    P0339 Intermittent DPKV signal
    • Poor contact in the connector
    • Damage to the wire shielding
    1. Re-crimp the connector
    2. Replace wiring

    Feature Primera P12: error P0336 often accompanied P0325 (problems with the knock sensor). This is due to the fact that both sensors are connected to the same ECU module. If after replacing the DPKV errors remain, check engine weight - on Primera P12 it often oxidizes near the battery.

    What happens if you ignore the P0336 code?

    Long-term driving with a faulty DPKV leads to:

    • 🔥 Catalyst overheating (due to rich mixture).
    • ⚡ Breakdowns in the ignition system (The computer increases the opening time of the injectors).
    • 💥 Flywheel damage (if the reason is chips on the sensor).

    In critical cases, the engine can go into mode "limpa" (speed limit to 3000 rpm).

    How to replace the crankshaft sensor Nissan Primera P12 with your own hands?

    Replacing DPKV with Primera P12 takes 30–40 minutes. You will need:

    • 🔧 10 mm wrench (for fastening bolt).
    • 🔌 Screwdriver with a flat blade (for the connector lock).
    • 🧴 WD-40 or similar cleaner (if the bolt is sour).
    • 📦 New sensor (original Nissan 23731-4M200 or analogues Bosch 0 261 210 115, Denso 5503101).

    Step by step instructions:

    1. Removing the crankcase protection:

      Unscrew the 4 10mm bolts holding the plastic shield. On Primera P12 It may also be necessary to remove the metal protection from the automatic transmission (2 bolts of 14 mm).

    2. Disconnecting the connector:

      Press the plastic lock (arrow on the connector) and pull it up. If the contacts are oxidized, clean them alcohol solution (not WD-40!).

    3. Removing the sensor:

      Unscrew the fastening bolt. If the sensor is stuck, gently shake it with pliers, but do not use excessive force - the core is fragile!

    4. Installing a new sensor:

      Clean the seat from any dirt. Install the new sensor, tighten the bolt to torque 8–10 Nm. Connect the connector until it clicks.

    5. Reset errors:

      After replacement, reset the errors using a scanner or by disconnecting the battery terminal for 10 minutes. Start the engine and let it idle for 5-7 minutes - the ECU should “relearn”.

    💡

    Before installing a new sensor, apply a little dielectric grease on the connector contacts - this will prevent oxidation in the future.

    On Primera P12 with engine QR25DE after replacing the DPKV it may be necessary throttle adaptation (procedure “Throttle Valve Closed Position Learning”). To do this:

    1. Включите зажигание на 3 секунды.

    2. Выключите зажигание на 10 секунд.
    

    3. Повторите шаги 1–2 ещё 2 раза.
    

    4. Заведите двигатель и дайте ему поработать 20 секунд на холостых.

    Which crankshaft sensor to choose for Nissan Primera P12?

    There are original and similar sensors on the market. Here is a comparison table:

    Manufacturer Article Price, rub. Features Recommendation
    Nissan (original) 23731-4M200 3 500–4 200 12 month warranty, accurate signal calibration ⭐ Best choice for long-term performance
    Bosch 0 261 210 115 2 800–3 300 Good quality, but may require ECU adaptation ✅ Optimal price/quality ratio
    Denso 5503101 3 000–3 600 Highly reliable, but rarely found in stores ✅ A good alternative to the original
    Febi, Meyle Various 1 500–2 200 Low signal quality, frequent failures after 10–15 thousand km ❌ Not recommended

    Important nuance: on Primera P12 with engine QR20DE (1.8 l) suitable sensor from QR25DE (2.5 l), but not vice versa! They have different signal calibration. Also note o-ring — complete with non-original sensors it is often missing (original article number: 11956-4M000).

    💡

    Never buy sensors without manufacturer's markings or with the inscription "Made in China" without a brand. On Primera P12 such sensors fail on average after 8–12 months due to an unstable signal.

    Frequent mistakes when replacing DPKV with Nissan Primera P12

    Even experienced craftsmen make mistakes when working with DPKV. That's what can't do:

    • 🛑 Use sealant when installing the sensor, it can get on the core and distort the signal. A clean seating surface and a new O-ring are sufficient.
    • 🛑 Tighten the fastening bolt with a force of more than 10 Nm - this will deform the sensor body and lead to its premature failure.
    • 🛑 Ignore clearance check between the sensor and the flywheel. On Primera P12 he must be 0.5–1.5 mm. With a smaller gap, the sensor will cling to the flywheel; with a larger gap, the signal will weaken.
    • 🛑 Don't reset errors after replacement. ECU Primera P12 may continue to use old data, which will lead to unstable engine operation.

    Another common problem is connector damage when disconnected. On Primera P12 The connector lock is plastic and often breaks. If this happens, replace the entire connector (part number: 28521-4M000). Soldering wires without a connector is not recommended - engine vibration will quickly destroy the connection.

    ⚠️ Attention: After replacing the DPKV with Primera P12 with automatic transmission may be required reset box adaptations. If gear changes are jerky, perform the AT Learning procedure via CONSULT-III or similar scanner.

    FAQ: Frequently asked questions about the crankshaft sensor Nissan Primera P12

    Is it possible to drive with a faulty DPKV?

    Technically possible, but highly undesirable. The ECU goes into emergency mode, which leads to:

    • 🔥 Increased fuel consumption (up to 20–30%).
    • ⚡ Risk of damage to the catalyst (due to a rich mixture).
    • 💥 Unstable engine operation, especially at idle.

    On Primera P12 with automatic transmission, long-term driving with a faulty DPKV can cause box overheating due to incorrect ECU signals.

    Why did the P0335 error persist after replacing the sensor?

    Probable reasons:

    1. Wiring fault — check the wires from the sensor to the ECU (pin 25 on the ECU connector).
    2. Poor engine weight — check the connection near the battery.
    3. Poor quality sensor - even new sensors can be defective (especially no-name).
    4. Problems with the ECU - on Primera P12 after 2005, the control unit sometimes becomes “glitchy” (re-flashing is required).
    What clearance should there be between the DPKV and the flywheel?

    On Nissan Primera P12 nominal clearance is 0.5–1.5 mm. You can check it:

    • 📏 With a feeler gauge (valve adjustment kit).
    • 🔍 Visually — if a gap of more than 2 mm is visible between the sensor and the flywheel, adjustment is required.

    If the gap is exceeded, this may be caused by:

    • Wear of the sensor seat.
    • Deformation of the flywheel (for example, after an impact).
    Is it possible to clean the old sensor?

    Cleaning is possible, but not always effective. Algorithm:

    1. Wash the sensor core alcohol solution (not gasoline!).
    2. Remove metal shavings using soft brush.
    3. Check the resistance - if it is outside the norm (550–750 Ohms), the sensor must be replaced.

    Cleaning will help if the problem was contamination. If the sensor “died” due to an internal winding break, cleaning is useless.

    Where to buy an original sensor for Primera P12?

    Original sensor Nissan 23731-4M200 you can order:

    • 🛒 Official dealers Nissan - 12 month warranty, but the price is higher.
    • 🌍 Online stores (Exist.ru, Autodoc, Emex) - often there are discounts.
    • 🏗️ Showdown - only if the sensor is removed from a car no older than 3–5 years.
