Nissan Almera Classic (also known as Nissan Almera B10 or Samsung SM3 in some countries) is a popular sedan with a reliable engine QG16DE (1.6 l). However, even time-tested engines have weak points, and one of them is Crankshaft position sensor (CPS). This small element is responsible for synchronizing the operation of the ignition and fuel injection systems, and its failure leads to a complete stop of the engine.

Owners Almeri Classic often encounter problems with DPKV after 100–150 thousand kilometers. The reason is winding wear, contact corrosion or mechanical damage. In this article we will analyze original sensor articles, suitable analogues, signs of malfunction and step-by-step replacement instructions. You will also learn how to check the DPKV with a multimeter and avoid buying a fake.

Signs of a faulty DPKV on Almera Classic

The crankshaft sensor rarely fails suddenly - usually the malfunction appears gradually. Here are the main symptoms that should alert you:

  • 🚗 Engine stalls at idle or it works unstably (speeds fluctuate).
  • 🔥 Misfires, especially in humid weather (condensation gets into the connector).
  • ⚡ Check Engine lights up and goes out randomly. Error code P0335 (failure of the DPKV circuit) is a direct sign of a problem.
  • 🛑 Engine won't startalthough the starter turns. This occurs when the sensor has completely failed.
  • 📉 Power Loss and “failures” during acceleration - the ECU receives incorrect data about the position of the crankshaft.

Feature Almera Classic — false positives sensor when the contacts are heavily soiled or oxidized. For example, after washing the engine or driving through deep puddles. In such cases, it is enough to dry and clean the connector for the problem to disappear.

⚠️ Attention! If the dashboard lights up Check Engine, and the engine is running rough, don’t rush to change the DPKV. Check first spark plugs And high voltage wires - their malfunction gives similar symptoms.

How to check the crankshaft sensor with a multimeter

Before replacing the DPKV, you can check it yourself using a multimeter. To do this:

  1. Remove the sensor from the engine (located next to the crankshaft pulley, secured with one 10mm bolt).
  2. Clean the housing from dirt (use WD-40 or alcohol).
  3. Set the multimeter to resistance measurement mode (200 ohms).
  4. Connect the probes to the sensor terminals. The winding resistance must be within 550–750 Ohm.

If resistance:

  • 🔴 Close to 0 ohm - short circuit in the winding.
  • 🔴 More than 1 kOhm - circuit break.
  • 🟢 Normal (550–750 Ohm) — the sensor is working, the problem may be in the wiring or the ECU.

Also check wire insulation for damage. Often rubbing against the engine body leads to a short circuit.

Step-by-step instructions for replacing the crankshaft sensor

Replacing DPKV with Nissan Almera Classic takes no more than 20 minutes. You will need:

  • 🔧 10 mm key or socket.
  • 🔌 Screwdriver with a flat blade (for disconnecting the connector).
  • 🧴 WD-40 or contact cleaning fluid.
  • 📦 New sensor (check the contents before installation).

Procedure:

  1. Disconnect the negative terminal of the battery (required!).
  2. Find the sensor - it is located to the right of the oil filter, next to the crankshaft pulley. There will be a plastic connector on it.
  3. Press the connector lock and disconnect it. If the contacts are oxidized, clean them WD-40.
  4. Unscrew the sensor mounting bolt with a 10 mm wrench.
  5. Carefully remove the sensor without damaging the O-ring.
  6. Install the new sensor, tighten the bolt firmly 8–10 Nm (do not overtighten!).
  7. Connect the connector and return the terminal to the battery.
⚠️ Attention! When installing a new sensor, be careful the gap between the core and the toothed rim of the pulley. He must be 0.5–1.5 mm. If the gap is larger, the sensor will not read the signal correctly.
💡

Before installing a new sensor, apply a thin layer of dielectric grease to the connector contacts - this will prevent oxidation.

Common mistakes when replacing DPKV and how to avoid them

Even experienced car owners make mistakes when replacing the crankshaft sensor. Here are the most common:

Error Consequences How to avoid
Using a sensor with a different connector Incompatibility with the ECU, the engine will not start Check the article number and visually compare the connectors
Tightening the fastening bolt Damage to the sensor housing or threads in the block Tighten to a maximum torque of 10 Nm
Installation without O-ring Oil and dirt getting on the core, rapid failure Check that the new sensor is complete
Ignoring the gap between the sensor and the pulley Incorrect signal, misfire Use a 1mm thick feeler gauge to check

Another typical problem is buying a fake sensor. There are many counterfeit branded parts on the market Bosch And Denso. To avoid being scammed:

  • 🛒 Buy only from trusted stores (for example, Exist.ru, AutoDoc).
  • 🔍 Check the hologram and serial number on the package.
  • 📦 Compare the weight and quality of the plastic with the original.
How to distinguish original Bosch from a fake?

The original Bosch sensor has:

1. Clear markings on the body (no blurry symbols).

2. Wire with uniform braiding and brand marks every 10 cm.

3. Packaging with a hologram and a QR code for checking on the manufacturer’s website.

Counterfeits are often 10–15 grams lighter and have a strong plastic smell.

Cost of service replacement vs self-repair

If you are not confident in your abilities, you can entrust the replacement of the DPKV to the service. However, prices for this service vary greatly:

Service type Cost of work (rub.) Sensor cost (RUB) Total (RUB)
Official dealer Nissan 1 500–2 500 3,500–4,500 (original) 5 000–7 000
Independent service 800–1 500 1,500–2,500 (analog) 2 300–4 000
Self-replacement 0 1 200–2 500 1 200–2 500

As can be seen from the table, DIY replacement saves up to 70% cost. The main thing is to follow the instructions and take your time. If the problem remains after replacing the sensor, the cause may be:

  • 🔌 Damaged wiring from DPKV to ECU.
  • 🖥️ Malfunction of the ECU itself (for example, oxidation of contacts in the connector).
  • 🔧 Mechanical damage to the crankshaft pulley ring gear.
💡

If after replacing the DPKV the engine does not start, check the sensor power circuit (12 V on one of the connector contacts) and the signal wire (with an oscilloscope or multimeter in AC voltage mode).

FAQ: Frequently asked questions about the crankshaft sensor on Almera Classic

Is it possible to drive with a faulty DPKV?

No. The crankshaft sensor is a critical element of the engine management system. If it breaks down, the ECU cannot determine the position of the crankshaft, which leads to complete engine stop. In rare cases, the engine may start, but will operate with severe interruptions and a high risk of damage to the catalyst.

Which sensor is better to choose: original or analogue?

Original sensor (23731-4M500) more reliable, but more expensive. If your budget is limited, choose analogues Bosch 0 261 210 115 or Denso 550-0103 — they showed good results in practice. Avoid cheap no-name options, as they often fail after 10–20 thousand km.

What should I do if the Check Engine light comes on after replacing the DPKV?

Reset the error using a scanner (for example, ELM327) or by disconnecting the battery for 10 minutes. If the error appears again, check:

  • Quality of sensor installation (gap, fastening).
  • Integrity of wiring from sensor to ECU.
  • Condition of the pulley ring gear (are there any chips or wear on the teeth).
Is it possible to clean the old sensor instead of replacing it?

Cleaning is possible, but does not guarantee restoration of functionality. Clean the core and contacts from oil and dirt using isopropyl alcohol or WD-40. If the problem was contamination, the sensor will work. However, if the winding is internally broken or the housing is damaged, cleaning will not help.
