Replacing the crankshaft sensor on a Nissan Almera Classic: instructions with photos and tips

Crankshaft position sensor (CPS) on Nissan Almera Classic - A critical element of the engine management system. Its malfunction leads to engine malfunctions, difficult starting or a complete stop of the car. Model owners B10 (1995–2000) and N16 (2000–2006) often encounter this problem after 150–200 thousand km, when the factory sensor fails.

In this article you will find detailed instructions for replacing the DPKV with photos, list of tools and diagnostic tips. We will look at how to distinguish an original sensor from a fake, what errors occur when it breaks (P0335, P0336), and why even a new sensor may not solve the problem. If your Almera Classic stalls while driving or has trouble starting - this article will help you save money at the service station.

Signs of a faulty crankshaft sensor on a Nissan Almera Classic

DPKV has no mechanical wear, but its electrical part suffers from temperature changes, vibrations and corrosion. The first symptoms of a breakdown are often confused with problems with the fuel system or spark plugs. Pay attention to these key features:

• 🔴 Engine won't start or starts only after several attempts (typical of a “cold” start).
• 🚗 They arise on the go power dips, especially during hard acceleration or at low speeds.
• ⚡ Lights up on the dashboard Check Engine with errors P0335 ("Crankshaft sensor circuit") or P0336 (“Circuit Range/Performance”).
• 🔄 Engine stalls at idle or it works unstably (speeds fluctuate).
• 🛑 In rare cases, the engine suddenly stalls while driving, and restarting becomes impossible.

Important: similar symptoms may cause malfunctions camshaft sensor, timing belt or wiring. Before replacing the DPKV necessarily check the circuit with a multimeter (the resistance of a working sensor is 550–750 Ohm).

⚠️ Attention: If the problem persists after replacing the sensor, check gap between sensor and flywheel (must be 0.5–1.5 mm). On Almera Classic it is regulated by gaskets - their absence or deformation leads to false signals.

Which crankshaft sensor to choose for Nissan Almera Classic

On Almera Classic Two types of sensors were installed depending on the year of manufacture and engine:

Engine model	Original art.	Analogs (brand/art.)	Average price, ₽
GA14DE (1.4 L, 1995–2000)	23731-4M000	Bosch 0 261 210 115, Era 550471	1 200–2 500
GA16DE (1.6 L, 2000–2006)	23731-4M010	Denso 550-0101, Blue Print ADG02304	1 500–3 000
QG15DE (1.5 l, restyling)	23731-4M025	NGK DCK2003, Febi 23731	1 800–3 200

Selection tips:

• 🔍 Original (Nissan) guarantees compatibility, but is often counterfeited. Check the packaging for the presence of a hologram and barcode.
• 💰 Budget analogues (Era, Febi) are suitable for temporary replacement, but their service life is 30–40% lower.
• ⚠️ Avoid sensors that are not marked or labeled "Made in China" without a brand - they can give false signals.

Critical point: on Almera Classic with a GA16DE engine, the sensor is fastened with an M6 bolt, and on GA14DE - M5. When purchasing, check this detail, otherwise the new sensor will not fit into place.

Tools and preparation for replacing the crankshaft sensor

To replace DPKV with Nissan Almera Classic no pit or lift required - just a jack and a basic set of tools. Here's what you'll need:

New crankshaft sensor (check part number)|10mm socket wrench or extension socket|Flat head screwdriver (to remove chip)|Multimeter (to check resistance)|WD-40 or similar cleaner (for rusty bolts)|Sensor spacer (if lash adjustment needed)|Jack and jack stands (to lift front end)|Clean rags (for cleaning seat)-->

Before starting work:

1. Disable negative battery terminal (this will reset the ECU errors and prevent a short circuit).
2. If the engine is hot, let it cool - the plastic sensor chip may become deformed when removed.
3. Clear the area around the sensor of dirt to prevent debris from getting into the flywheel housing.

⚠️ Attention: On Almera Classic N16 (2000–2006) the sensor is located under the starter. If you have a weak jack, prepare wooden blocks in advance for insurance - the starter weighs ~5 kg, and its accidental fall can damage the wiring.

Step-by-step instructions for replacing the crankshaft sensor

The placement of the DPKV depends on the engine model. On GA14DE/GA16DE he is on oil pump housing (from the checkpoint side), on QG15DE - on cylinder block近crankshaft. Follow the instructions:

1. Removing the starter (N16 only).

   Unscrew the 2 starter mounting bolts (14 mm wrench) and disconnect the power supply. Carefully move the starter to the side - it remains hanging on the wire.

2. Removing the sensor.

   Press the plastic chip retainer and disconnect the connector. Using a 10 mm wrench, unscrew the sensor mounting bolt. Remove the sensor by rocking it from side to side (do not pull by force - you may damage the housing!).

3. Cleaning the seat.

   Remove the old gasket (if there was one) and clean the surface of oil and dirt. Check the integrity of the wiring - often chafing of the insulation causes false alarms.

4. Installing a new sensor.

   Insert the sensor all the way, making sure it sits evenly. Tighten the fastening bolt (tightening torque - 8–10 Nm). Connect the chip.

5. Checking the gap.

   On Almera Classic the gap between the sensor and the flywheel should be 0.5–1.5 mm. If it is larger, place a washer of appropriate thickness.

After assembly, connect the battery and start the engine. Error Check Engine should go out after 2-3 startup cycles. If not, reset it programmatically (for example, through ELM327).

What should I do if the engine does not start after replacing the sensor?

1. Check the connection of the chip - often the contacts oxidize or do not snap completely into place.

2. Make sure that the sensor is inserted all the way (sometimes it gets stuck on the gasket).

3. Measure the resistance of the new sensor - if it is outside the range of 550–750 Ohms, it is defective.

4. Check the sensor’s power supply circuit (there should be +12V and ground on the chip).

5. Inspect the flywheel for damage to the teeth - they may interfere with the signal.

Typical mistakes when replacing DPKV and how to avoid them

Even experienced car owners make mistakes that lead to repeated breakdowns or unstable operation of the engine. Here are the most common:

• 🔧 Tightening the fastening bolt. This deforms the sensor body and disrupts the gap. Use a torque wrench or hand tighten with moderate force.
• 🧲 Ignoring magnetic properties. If a metal object (for example, a key) does not stick to the sensor, it is faulty - the magnetic field has weakened.
• 🔌 Damage to the chip during removal. Plastic latches are fragile. If the chip is cracked, replace it entirely (art. 24520-4M000).
• 📏 Incorrect clearance. On Almera Classic a gap of >2 mm leads to signal misses, and <0.3 mm leads to mechanical contact with the flywheel.

One more hidden problem — corrosion on the ECU contacts. If after replacing the sensor the error P0335 returns, clean the contacts of the control unit (located under the glove compartment) with alcohol or a special cleaner.

Diagnostics of the crankshaft sensor without a scanner

If you do not have diagnostic equipment, you can check the DPKV using a multimeter and simple tests. Here are 3 methods:

1. Checking resistance.

   Switch the multimeter to ohmmeter mode and connect the probes to the sensor terminals. Resistance of a serviceable DPKV - 550–750 Ohm. Indications 0 ohm (short circuit) or ∞ (break) indicate a malfunction.

2. Inductance check.

   Switch the multimeter to inductance mode (if supported). Norm for Almera Classic — 200–400 mH. Values below 150 mH indicate an interturn short circuit.

3. Visual inspection.

   Look for cracks in the housing, traces of oil or corrosion on the contacts. The magnetic core must be clean - dirt on it distorts the signal.

Additional test: if the sensor is working properly, when you bring a metal object to its end, a click should be heard (the magnetic field attracts the object). The absence of a click is a sign of a malfunction.

When replacing the sensor does not solve the problem

If after installing a new DPKV the symptoms persist, the cause may lie in other nodes:

Problem	Signs	How to check
Damaged flywheel	Engine stalls at high speeds	Remove the starter and inspect the flywheel teeth
Broken wiring	Error P0335 appears periodically	Ring the circuit from the sensor to the ECU
Faulty ECU	Errors P0335 And P0336 together	Checking the power supply of the unit (+12V, ground)
Timing timing mark offset	The engine is tripping, phase errors	Checking the alignment of the marks on the pulleys

On Almera Classic N16 common problem - oxidation of the ECU "mass" (located under the bolt securing the block to the body). Clearing this contact solves the problem in 30% of cases of “false” DPKV errors.

FAQ: Frequently asked questions about replacing the crankshaft sensor

Is it possible to drive with a faulty crankshaft sensor?

No. DPKV is the only sensor without which the engine won't work. If it breaks down, the ECU cannot determine the position of the crankshaft, so fuel is not supplied and the ignition does not work. In rare cases, the engine may start, but will stall after 2-3 seconds.

Which crankshaft sensor is suitable for Almera Classic 1.6 2003?

For GA16DE (2000–2006) original art. — 23731-4M010. Suitable analogues: Denso 550-0101, Blue Print ADG02304, NGK DCK2003. Make sure that the kit includes a gasket - it is often missing on restyled models.

Do I need to reset the error after replacing the sensor?

Error P0335 will reset automatically after 2-3 successful engine starts. If Check Engine continues to light, reset the error programmatically (via ELM327 or scanner) or by disconnecting the battery for 10 minutes. If the error returns, the problem is not with the sensor.

What happens if the sensor is installed incorrectly?

If the sensor is installed crookedly or with an incorrect gap, the engine will run unstably (dips, jerking), and the dashboard will light up. Check Engine. In the worst case, the ECU will go into emergency mode, limiting the speed to 2,500–3,000 rpm.

How long does the crankshaft sensor last on Almera Classic?

Service life of the original sensor - 150–200 thousand km. Analogs last less: budget (Era, Febi) - up to 100 thousand km, premium (Bosch, Denso) - up to 180 thousand km. The service life is affected by operating conditions: frequent starts in cold weather, off-road driving (vibrations) and oil getting on the sensor housing.
