The crankshaft position sensor (CPS) is one of the critical elements of the engine management system. Nissan Almera. Its malfunction leads to engine malfunctions, difficult starting or 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 to determine a sensor malfunction on models Almera Classic (B10), Almera N16 And Almera G15, choose a high-quality replacement and do the repairs yourself. We will pay special attention to typical diagnostic errors and installation nuances that even experienced car owners often miss.

Signs of a faulty crankshaft sensor on a Nissan Almera

Symptoms of DPKV failure on Nissan Almera can appear either gradually or suddenly. The most common signs:

  • 🔴 Engine won't start or stalls immediately after starting - the most obvious symptom indicating a lack of signal from the sensor.
  • 🔧 Floating speed at idle (from 500 to 1500 rpm) for no apparent reason.
  • ⚡ A sharp drop in power, especially during acceleration - the car is “stupid” and does not respond to the gas pedal.
  • 🚨 Lights up on the dashboard Check Engine, but the scanner gives errors P0335 (DCCV circuit malfunction) or P0336 (signal outside the permissible range).

It is important to distinguish the symptoms of a faulty DPKV from problems with camshaft sensor or ignition coils. For example, if the engine stalls but starts, most likely it is not the crankshaft that is to blame, but the spark plugs or high-voltage wires. But the complete absence of a spark with working coils and the ignition module almost always indicates DPKV.

⚠️ Attention: On Almera N16 with engine QG15DE A faulty DPKV may manifest itself as a false alarm of the immobilizer. If the key is not recognized and the immo lamp is blinking, check the sensor first.

Crankshaft sensor diagnostics: 3 ways to check

Before changing the DPKV, make sure that this is the problem. Here are three proven diagnostic methods:

1. Visual inspection

Remove the sensor (the process is described below) and inspect it for:

  • 🔍 Cracks or chips on the case.
  • 🧲 The presence of metal shavings at the end - it violates the gap between the sensor and the synchrodisk.
  • 🟤 Contact oxidation or wiring damage.

2. Check with a multimeter

Switch the tester to ohmmeter mode and measure the resistance between the DPKV terminals:

  • 📊 Norm for Nissan Almera: 550–750 Ohm (depending on temperature).
  • ❌ If the resistance tends to zero or infinity, the sensor is faulty.

3. Checking with an oscilloscope (for advanced)

Connect the oscilloscope to the signal wire of the sensor (usually red or yellow) and start the engine. A working DPKV should issue clear sine wave no gaps. Chaotic bursts or lack of signal are a sign of a breakdown.

Test method Required Tools Time Accuracy
Visual inspection Screwdriver, flashlight 5–10 min Low (detects only mechanical defects)
Testing with a multimeter Multimeter 10–15 min Medium (does not check signal)
Oscilloscope Oscilloscope, wires 20–30 min High (diagnoses electrical faults)
💡

If you don’t have an oscilloscope at hand, use an LED probe: connect it to the signal wire of the sensor and rotate the crankshaft with the starter. A working DPKV will cause the LED to blink at rotation speed.

Choosing a crankshaft sensor for Nissan Almera: original vs analogues

When purchasing a new DPKV for Almera important to consider engine modification and year of manufacture. Original sensors are produced by the company Hitachi or Mitsubishi Electric and have articles:

  • 🔹 23731-4M500 - for Almera Classic (B10) with engine GA15DE.
  • 🔹 23731-5M500 - for Almera N16 (QG15DE/QG18DE).
  • 🔹 23731-ED00A - for Almera G15 (HR15DE).

Among the analogues, the following have proven themselves well:

  • 🔧 Blue Print (ADT32103) - a budget option with good compatibility.
  • 🔧 Febi Bilstein (23731) - German quality, close to the original.
  • 🔧 Valeo (587038) - optimal price/quality ratio.
⚠️ Attention: When buying an analogue, be sure to check connection connector - on Almera N16 And G15 they are different! Also avoid sensors without an O-ring - they are not sealed.

Average price of the original sensor - 2500–4000 rubles, analogues - 800–1800 rubles. It is not recommended to buy a used DPKV: the sensor’s life is limited, and it is impossible to check its condition without special equipment.

How to distinguish a fake from the original?

Fake sensors often have:

1. Uneven seam line on the body (the original is perfectly smooth).

2. Faded markings (the original has clear engraving).

3. Plastic connector instead of metal.

4. No hologram or label with a QR code (original Nissan parts always have one).

Step-by-step instructions for replacing the crankshaft sensor

Replacing DPKV with Nissan Almera does not require special skills, but will require accuracy. The work is carried out on an inspection pit or overpass. Replacement time - 30–60 minutes.

Required tools:

  • 🔧 Head on 10 mm or key.
  • 🔧 Extension and ratchet handle.
  • 🔧 Screwdriver with a flat blade (for removing the chip).
  • 🔧 Torque wrench (optional, for precise tightening).
  • 🧴 WD-40 or similar cleaner (if the bolt is stuck).

Work order:

  1. Disconnect the battery (remove the negative terminal) to avoid short circuit.

  2. Remove plastic engine protection (if available) to access the sensor.

  3. Find the DPKV - it is located on the oil pan, next to the crankshaft pulley. On Almera N16 The sensor may be hidden under the crankcase ventilation pipe.

  4. Disconnect electrical connectorby pressing the latch (do not pull the wires!).

  5. Unscrew the sensor mounting bolt (usually 10 mm) and carefully remove it. If the sensor gets stuck, do not use force - spray WD-40 and wait 5-10 minutes.

  6. Install the new sensor, observing gap between the end and the synchro disk (usually 0.5–1.5 mm). Tighten the bolt to torque 8–12 Nm.

  7. Connect the connector and check the operation of the engine.

Is the battery terminal disconnected?|Is the O-ring installed on the new sensor?|Is the mounting bolt tightened?|Is the connector connected until it clicks?|Has the tool been removed from under the hood?-->

If the engine does not start after replacement, check:

  • 🔌 Correct connection of the connector (mixed up wires are a common mistake).
  • 🔧 Tightening the bolt - weak fastening leads to vibrations and false signals.
  • 🛠️ Condition of the synchrodisc (gear ring) on the crankshaft - damaged teeth require replacement of the pulley.
💡

On Almera G15 with engine HR15DE The crankshaft sensor is located under the starter. To access it you will have to remove the starter or use a flexible extension.

Typical mistakes when replacing DPKV and how to avoid them

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

  1. Ignoring the error code. If Check Engine lights up after replacement, do not reset the error immediately - first check with a scanner. The problem may not be with the sensor, but with the wiring or the ECU.

  2. Connector damage. When disconnecting a chip, many people pull on the wires rather than the body. This leads to broken contacts. Always press down on the plastic release!

  3. Failure to maintain clearance. If the sensor is recessed too deeply or, conversely, protrudes, the signal will be incorrect. Use a feeler gauge to check the clearance.

  4. Saving on O-ring. Many analogues come without a ring, and the original one is often lost when removed. Without it, oil gets into the sensor and it quickly fails.

Another common problem is ingress of metal shavings to the end of the sensor. This occurs if the seat is not cleaned before installation. Use carbcleaner and a lint-free cloth for cleaning.

⚠️ Attention: On Almera N16 with automatic transmission, when replacing the DPKV, it may be necessary throttle valve relearning. If after repair the speed “floats”, perform the procedure for resetting adaptations through a diagnostic scanner or by disconnecting the battery for 10 minutes.

Cost of service replacement vs self-repair

The price of replacing DPKV at a car service depends on the region and model Almera:

Model Cost of work (rub.) Sensor cost (RUB) Total (RUB)
Almera Classic (B10) 800–1200 900–2500 1700–3700
Almera N16 1000–1500 1200–3500 2200–5000
Almera G15 1200–1800 1500–4000 2700–5800

Replacement yourself saves money 50–70% cost. However, if you do not have experience working with car electronics, it is better to entrust the repair to professionals - installation errors can lead to damage to the ECU or wiring break.

When choosing a service, give preference to those who specialize in Nissan. They have the necessary diagnostic equipment (eg Consult-III) and original spare parts catalogues.

Prevention: how to extend the life of the crankshaft sensor

Average resource of DPKV for Nissan Almera — 100–150 thousand km, but under unfavorable conditions it can fail after 50 thousand km. To extend sensor life:

  • 🛢️ Monitor the quality of the oil. Metal shavings and dirt in the oil settle on the end of the sensor, disrupting its operation. Change the oil every 7–10 thousand km.
  • 🔌 Check the wiring. Frayed or oxidized wires create signal interference. Inspect the sensor harness at every service.
  • 🚗 Avoid driving through deep puddles. The DPKV is located low and water can get into the connector, causing corrosion.
  • 🔧 Don't Ignore the Check Engine. Even if the engine is running normally, the error P0335/P0336 requires immediate diagnosis.

On Almera N16 And G15 With turbo engines, the crankshaft sensor is subject to increased loads due to vibrations. In this case it is recommended every 30 thousand km Clean it from oil deposits with compressed air.

💡

If you frequently drive off-road, install additional oil pan protection. This will protect not only the DPKV, but also the engine itself from damage.

FAQ: Frequently asked questions about replacing the crankshaft sensor on a Nissan Almera

Is it possible to drive with a faulty crankshaft sensor?

No. DPKV is a critical element of the engine management system. Without it, the ECU cannot determine the position of the crankshaft, which makes starting the engine impossible. In rare cases, the engine may start, but will operate extremely unstable and stall.

Which crankshaft sensor is suitable for Almera N16 1.8?

For Almera N16 with engine QG18DE original sensor fits 23731-5M500 or analogues: Blue Print ADT32103, Febi 23731. Make sure that the sensor has an O-ring - without it it will quickly fail.

What happens if the sensor is installed incorrectly?

If the sensor is installed with a gap violation (more than 1.5 mm) or skewed, the signal will be unstable. This will result in:

  • Difficulty starting the engine.
  • Floating revolutions.
  • Loss of power.
  • Constant burning Check Engine.

In the worst case, the ECU may go into emergency mode, limiting the speed to 2000–3000 rpm.

Do I need to reset errors after replacing the sensor?

Yes, but not right away. After replacement:

  1. Connect the battery.
  2. Start the engine and let it run for 5-10 minutes.
  3. If Check Engine went out on its own - the error was reset automatically.
  4. If the lamp is on, use a scanner to reset (for example, ELM327).

On Almera G15 The throttle may need to be relearned.

Is it possible to clean the crankshaft sensor?

Cleaning is possible, but not always effective. If the sensor is contaminated with oil or chips, wipe its end lint-free cloth, soaked in isopropyl alcohol or carbcleaner. However, if the problem is in the internal electronics (winding breakage, magnet damage), cleaning will not help - only replacement.
