Where is the crankshaft sensor located on Nissan Almera Classic (N16) - photo, diagram and signs of malfunction

The crankshaft position sensor (CPS) is a critical element of the engine management system. Nissan Almera Classic (body N16). Its incorrect operation leads to ignition failures, loss of power or complete engine failure. Owners often face the problem of finding this sensor: the manuals contain general diagrams, but in practice, access to it is difficult due to the dense layout of the engine compartment.

In this article you will find exact location of DPKV with reference to visual references (photos and diagrams), as well as unique symptoms of malfunction specific to Almera Classic with engines QG15DE And QG18DE. We will look at how to check the sensor with a multimeter without dismantling it, and we will warn you against typical replacement mistakes that can lead to damage to the wiring harness or the sensors themselves.

Exact location of the crankshaft sensor on Nissan Almera Classic (N16)

On Nissan Almera Classic (2006–2012) crankshaft sensor installed on oil pump housing, which is attached to the cylinder block from the side right (in the direction of travel) wheel. Visually it is easy to identify by:

• 🔧 Black plastic body with a metal core protruding towards the crankshaft pulley.
• 🔌 3-pin connector (white or gray), which is connected to the wiring harness running along the cylinder block.
• 📏 Distance ~1–1.5 mm between the end of the sensor and the toothed rim of the pulley (the gap is critical for correct operation!).

To access the sensor you must:

1. Remove plastic engine protection (4 bolts x 10 mm).
2. Disconnect air pipe from the air filter housing (the clamp clamp is loosened with an 8 mm wrench).
3. Lifting the car on a jack or driving it into a hole makes it easier to get to the sensor connector.

Photo of DPKV location

On most Almera Classic The crankshaft sensor is located to the right of the oil filter, next to the generator. Its body is directed towards the crankshaft pulley, and the connector “looks” upward, towards the ignition coils. On engines QG18DE The sensor may be partially covered by the injection system wiring harness.

Important! On models with air conditioning access is complicated by compressor tubes. In this case, it is recommended to temporarily remove the alternator belt to avoid accidental damage to the wiring.

How to distinguish a crankshaft sensor from a camshaft sensor

Beginners often confuse DPKV with camshaft position sensor (CPR), which is also installed on the cylinder block, but performs a different function. Here are the key differences:

Parameter	Crankshaft sensor (CPCV)	Camshaft sensor (DPRV)
Location	On the oil pump housing, next to the crankshaft pulley	On the cylinder head, next to cylinder 1
Case shape	Extended cylinder with cable ~30 cm	Compact rectangle with short cable
Connector	3 pins (white/gray)	3 pins (black)
Consequences of a malfunction	The engine does not start or runs intermittently	Increased fuel consumption, error P0340

On Almera Classic DPRV is located left (in the direction of travel) on the cylinder head, next to the valve cover. Its connector is usually hidden under the ignition coil wiring harness. If you see a sensor with short cable and a black connector - this is definitely a DPRV.

Signs of a malfunctioning crankshaft sensor on Almera Classic

Faulty DPKV on Nissan Almera Classic manifests itself with specific symptoms that can easily be confused with problems with the fuel system or ignition. Look out for the following signs:

• ⚡ The engine starts and immediately stalls - a typical symptom when the ECU receives an incorrect signal about the crankshaft position.
• 🔥 Misfire at idle, especially when the engine warms up to 60–70°C.
• 🚗 Jerks during acceleration at speeds of 60–90 km/h, accompanied by fire Check Engine.
• 🛑 Complete startup failure without a spark on the candles (in this case, the starter turns, but the engine does not “catch”).

Unique symptom for Almera Classic: if the DPKV is faulty, the indicator on the instrument panel may flash OIL (oil can), although the oil level is normal. This is due to the fact that the ECU mistakenly interprets the sensor signal as a critical error in the lubrication system.

⚠️ Attention! If the engine QG18DE suddenly stopped starting after washing the engine compartment; in 80% of cases, corrosion of the contacts in the DPKV connector is to blame. Before replacing the sensor, clean the contacts with alcohol and check the integrity of the wire insulation.

How to check the crankshaft sensor with a multimeter (step-by-step instructions)

Diagnosis of DPCV on Nissan Almera Classic does not require complex equipment - a digital multimeter with the function of measuring resistance and voltage is enough. Follow the algorithm:

Disconnect the negative terminal of the battery

Remove the connector from the sensor (press the lock and pull up)

Clean the contacts of the sensor and connector from oxidation (use WD-40 or alcohol)

Set the multimeter to resistance measurement mode (200 Ohm)

-->

1. Checking winding resistance:

   Connect the multimeter probes to the terminals 1 And 2 sensor connector (contacts are usually marked on the body). Normal resistance for Almera Classic: 550–750 Ohm. If the readings are below 500 Ohms or above 900 Ohms, the sensor is faulty.

2. Inductance test (optional):

   To do this you will need a megohmmeter or LCR meter. Normal inductance - 200–400 mH. Deviations indicate an interturn short circuit.

3. Checking the signal with an oscilloscope:

   Connect an oscilloscope to the sensor terminals (with the engine running). A healthy DPKV gives sine wave with an amplitude of at least 0.5 V. Chaotic bursts or lack of signal are a sign of a malfunction.

If the multimeter shows a break (resistance ∞), check the integrity of the wires from the sensor to the ECU. Often the problem lies in frayed insulation near the exhaust manifold.

Replacing the crankshaft sensor: step-by-step algorithm and typical errors

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

• 🔧 Socket wrench on 10 mm (for fastening bolt).
• 🧲 Magnet or tweezers - so as not to drop the bolt into the pan.
• 🧴Sealant Loctite 574 (optional, for fixing the thread).

Procedure:

1. Disconnect the negative terminal of the battery.
2. Disconnect the sensor connector by pressing the plastic clip.
3. Unscrew the fastening bolt with a 10 mm wrench. Attention! The bolt often “sticks” - do not use excessive force so as not to strip the thread.
4. Carefully remove the sensor by rocking it from side to side. Don't pull the wires!
5. Install the new sensor, aligning it with the seat. Tighten the bolt firmly 8–10 Nm (do not overtighten!).
6. Connect the connector and check the gap between the sensor and the ring gear - it should be 1–1.5 mm.

⚠️ Attention! On Almera Classic With an automatic transmission, when replacing the DPKV, it is necessary to remove the starter for ease of access. If this is not done, the risk of damaging the starter wiring harness increases 3 times.

Typical replacement mistakes:

• 🔴Usage non-original sensor without checking resistance. Cheap analogues often have resistance outside the range of 550–750 Ohms.
• 🔴 Fastening bolt tightening, leading to deformation of the sensor body.
• 🔴 Ignoring gap 1–1.5 mm. If the gap is more than 2 mm, the ECU will not be able to read the signal correctly.

Frequently asked questions about the crankshaft sensor on Nissan Almera Classic

Is it possible to drive with a faulty DPKV?

No. The crankshaft sensor is the only one in the system without which the engine won't start or will work with critical interruptions. Unlike the camshaft sensor or lambda probe, the DPKV directly affects spark formation and fuel injection. If the ECU does not receive a signal about the crankshaft position, the supply of gasoline to the cylinders is blocked.

Why does the engine still not start after replacing the DPKV?

The reasons may be as follows:

1. Incorrectly installed gap between the sensor and the ring gear (should be 1–1.5 mm).
2. Damaged wiring from the sensor to the ECU (check the circuit for an open circuit).
3. Not reset ECU errors (use a scanner or disconnect the battery for 10 minutes).
4. Installed incompatible sensor (check the resistance!).

Also make sure that when replacing you do not damage ring gear on the crankshaft pulley - its deformation leads to an incorrect signal.

Which scanner is suitable for diagnosing CPCV on Almera Classic?

To read errors related to the crankshaft sensor (for example, P0335), will fit:

• 📱 ELM327 Bluetooth + application Torque Pro (Android) or OBD Fusion (iOS).
• 💻 Diagnostic adapter VAG-COM (with protocol support ISO 9141-2).
• 🔧 Scan Tool Pro Black Edition - supports advanced diagnostics Nissan.

For Almera Classic it is important that the scanner supports the protocol Nissan Consult, otherwise specific errors may not be read, for example, P1320 (DPKV circuit malfunction).

Is it possible to clean the crankshaft sensor instead of replacing it?

Cleaning is possible, but is only effective in 20% of cases. Algorithm:

1. Remove the sensor and clean its housing from oil and dirt (use isopropyl alcohol).
2. Blow out the connector with compressed air (do not use metal objects!).
3. Check the resistance - if it is outside the norm (550–750 Ohms), the sensor must be replaced.

Cleaning will only help if the problem is dirty contacts. If the winding or magnetic core is faulty, the sensor needs to be replaced.

Where is the crankshaft sensor fuse located?

DPKV on Nissan Almera Classic does not have a separate fuse. Its circuit is protected by a fuse ECU-IG (10A) in the fuse box under the steering wheel (position #32). Also check the relay ECU (position #5), which is responsible for powering the ECU.

If the sensor does not produce a signal, but its resistance is normal, check:

• Integrity wires from the DPKV connector to the ECU (contacts 24 And 47 on the ECU block).
• Voltage at contact 3 sensor connector (should be 5V when the ignition is on).
