The crankshaft position sensor (CPS) is one of the key elements of the engine management system Nissan Almera Classic B10 (2006–2012). Its incorrect operation leads to ignition failures, unstable engine operation or complete startup failure. Owners often face the problem of finding this sensor: in the repair manual it is indicated schematically, but without reference to the actual location under the hood.
In this article you will find exact sensor coordinates with reference to visual landmarks, photo of its mounting on engines QG15DE And QG16DE, and also step-by-step instructions for checking and replacing. We will figure out why the error P0335 (failure of the DPKV circuit) appears even on new sensors, and how to avoid typical installation errors.
Where is the crankshaft sensor located on the Nissan Almera Classic B10: photo and diagram
On Almera Classic B10 The crankshaft sensor is located on oil pump housing, on the right side of the engine (when viewed in the direction of travel of the car). It is screwed into the cylinder block next to crankshaft pulley and is covered with a plastic timing belt guard. Visually it can be identified by:
- 🔧 Black plastic body with a connector for a chip (2 contacts).
- 📏 Location at the level of the middle of the pulley - approximately 10–15 cm from the bottom edge of the block.
- 🔗 Single bolt mounting (M6 thread, tightening torque 8–10 Nm).
On engines QG15DE (1.5 l) and QG16DE (1.6 l) location is identical, but on 1.6 liter version The sensor may be slightly biased towards the transmission due to the design of the oil pump. Below is a diagram showing the exact location:
DPKV location diagram on Almera Classic B10
| Landmark | Sensor distance | Note |
|---|---|---|
| Crankshaft pulley | 5–7 cm to the left | The sensor is directed to the ring gear of the pulley |
| Oil filter | 15–20 cm up | Located higher vertically |
| Timing cover | Adjacent to the right | Can be partially covered by a casing |
| Generator | 30–40 cm to the right | The sensor is closer to the front of the engine |
Important! On some modifications Almera Classic (eg for Asian markets) the sensor can be installed at a slight angle. If you do not find it in the specified location, check the availability stubs in the block - sometimes the sensor is hidden under it.
Signs of a faulty crankshaft sensor: how to recognize a breakdown
A faulty DPKV manifests itself differently depending on the nature of the damage. On Nissan Almera Classic B10 most common symptoms:
- ⚡ Engine won't start (the starter turns, but there is no spark).
- 🔥 Floating speed at idle (from 500 to 1500 rpm).
- 🚗 Jerks during acceleration, especially at speeds of 60–80 km/h.
- ⚠️ Check Engine with errors
P0335,P0336orP0339. - 🔧 Detonation when you press the gas sharply (a loud metallic knock).
Feature of Almera Classic B10: if the DPKV signal wire breaks, the engine can start, but will operate in emergency mode with a speed limit of up to 3000 rpm. This is due to the fact that the ECU switches to a backup algorithm for calculating the shaft position using the camshaft sensor.
To distinguish a malfunction of the DPKV from problems with camshaft sensor or ignition coils, do a simple check:
- Try starting the engine "push" (in 2nd gear). If the engine starts, the problem is in the DPKV.
- Check the voltage at the sensor connector with the ignition on (there should be 12 V between pins 1 and 2).
- Inspect the crankshaft pulley ring gear for damage or contamination with metal shavings.
- Engine won't start
- Floating speed
- Jerks during acceleration

How to check the crankshaft sensor on Nissan Almera Classic B10: 3 ways
Diagnosis of CPPV does not require specialized equipment - just a multimeter and a screwdriver. Below are three reliable verification methodswhich are suitable for engines QG15DE/QG16DE.
1. Checking the winding resistance
Disconnect the sensor connector and measure the resistance between its contacts. For Almera Classic B10 normal values:
- 📊 550–750 Ohm at a temperature of 20°C.
- 🌡️ When heating the sensor (for example, with a hairdryer), the resistance should increase by 10–15%.
If the resistance is below 500 Ohms or approaches infinity, the sensor is faulty.
2. Inductance check
To do this you will need a megohmmeter or LC meter. Normal parameters:
- 🔄 Inductance: 200–400 mH.
- 🛡️ Insulation resistance: More than 20 MΩ (tested at 500 V).
3. Check with an oscilloscope (the most accurate method)
Connect the oscilloscope to the sensor signal wire (pin 2) and start the engine. The screen should display sinusoid with amplitude 0.5–1.5 V and a frequency proportional to the crankshaft speed. No signal or signal instability indicates a malfunction.

Attention! ⚠️ On Almera Classic B10 after 2010, crankshaft sensors may have reverse polarity of the connector. Before checking, check the pinout according to the markings on the sensor body (usually located next to the contacts).
Step-by-step instructions for replacing the crankshaft sensor
Replacing DPKV with Nissan Almera Classic B10 takes no more than 30 minutes. You will need:
- 🔧 10 mm wrench (for fastening bolt).
- 🔨 Flat blade screwdriver (to remove a chip).
- 🧴 WD-40 or equivalent (if the bolt is soured).
- 📏 Probe 0.5 mm (to check the gap).
Procedure:
- Disconnect the negative terminal of the battery.
- Remove the timing belt guard (3 x 10mm bolts).
- Disconnect the sensor connector by pressing the latch.
- Unscrew the sensor mounting bolt and remove it.
- Clean the seat from dirt and metal shavings.
- Install the new sensor, maintaining the gap 0.5–1.2 mm between its core and the toothed rim of the pulley.
- Tighten the bolt to a torque of 8–10 Nm.
Critical error when replacing: ⚠️ Almera Classic B10 cannot use sensors from other Nissan models (for example, from Note or Tiida), even if they are visually identical. Differences in calibration cause the ECU to malfunction.
Before installing a new sensor, apply a thin layer of sealant (such as Loctite 577). This will prevent oil from entering the connector and corroding the contacts.
Mistakes when diagnosing and replacing DPKV: what not to do
Many owners Almera Classic B10 make typical mistakes that lead to repeated breakdowns or damage to the computer. Here are the most common:
- ❌ Using "universal" sensors no compatibility check. Even if the sensor fits the connector, its characteristics (inductance, resistance) may not meet the requirements of the ECU.
- ❌ Neglecting to check clearance. A gap of more than 1.5 mm leads to a weak signal, less than 0.3 mm leads to mechanical contact with the crown.
- ❌ Replacing the sensor without cleaning the seat. Metal shavings or dirt can cause a short circuit.
- ❌ Connecting the connector with the ignition on. This may damage the ECU input circuits.
Case study: After replacing the DPKV with Almera Classic 1.6 The engine continued to run erratically. The reason turned out to be that the master did not clean the ring gear of the pulley from rust, which is why the sensor read incorrect pulses. After cleaning, the problem disappeared.
If after replacing the sensor the error P0335 remains, check the integrity of the wiring from the sensor to the ECU. Often the problem lies in a frayed signal wire near the exhaust manifold.

Frequently asked questions (FAQ)
Is it possible to drive with a faulty crankshaft sensor?
Technically possible, but highly undesirable. The ECU will go into emergency mode, which will lead to:
- Increased fuel consumption (up to 20%).
- Loss of power (the engine will not develop more than 3000 rpm).
- Risk of damage to the catalyst due to incorrect mixture composition.
On Almera Classic B10 Driving for a long time with a faulty DPKV can cause errors in the operation of the gearbox (if an automatic transmission is installed).
What gap should be between the sensor and the pulley?
Optimal clearance for Nissan Almera Classic B10 — 0.5–1.2 mm. You can check it using a probe:
- Unscrew the sensor, but do not remove it completely.
- Insert the feeler gauge between the sensor core and the ring gear.
- If the 0.5 mm feeler gauge passes freely, but the 1.5 mm feeler gauge does not, the gap is normal.
A gap of more than 1.5 mm leads to a weak signal, less than 0.3 mm leads to mechanical contact due to vibration.
Why doesn't the new crankshaft sensor work?
There are several reasons:
- Incompatibility — the sensor does not meet the specifications (even if it is physically in place).
- Damaged wiring — frayed or oxidized signal wire.
- Dirty ring gear — rust or shavings interfere with reading.
- Incorrect clearance — the sensor is installed too far or close.
- ECU malfunction - rarely, but the control unit may not recognize the signal.
Check first connector voltage (should be 12 V when the ignition is on) and wiring integrity.
Is it possible to clean an old crankshaft sensor?
Cleaning is possible, but not always effective. Algorithm of actions:
- Remove the sensor and clean its housing from oil and dirt (use isopropyl alcohol).
- Check the core for the presence of metal shavings - if there are any, the sensor must be replaced.
- Blow out the connector with compressed air.
If the error remains after cleaning, the sensor is faulty. On Almera Classic B10 cleaning only helps in 20% of cases - usually the problem lies in a broken winding or damage to the magnetic core.
