The crankshaft position sensor (CPS) is one of the most critical elements of the engine management system. Nissan March (especially models K13 And K12 with motors HR12DE, HR15DE, CR14DE). Its failure leads to a complete stop of the engine or serious malfunctions. Despite its simple design, this sensor often becomes the source of problems that car owners mistakenly attribute to the fuel system or electronics.

In this article we will look at how independently diagnose a faulty DPKV on Nissan March, what tools are needed for replacement, and why even the original sensor can fail ahead of schedule. We will pay special attention unique features of HR series engines: their sensitivity to the gap between the sensor and the drive disk, which should be 0.5–1.2 mm — a deviation of just 0.3 mm can cause false signals.

Signs of a faulty crankshaft sensor on a Nissan March

Symptoms of DPKV failure on Nissan March often disguised as other problems. For example, misfire or bad start may indicate faulty spark plugs and the fuel pump. However there is unique features, which directly signal problems with the sensor:

  • 🔴 Engine stalls while driving without the possibility of restarting (in this case, the starter turns, but the motor does not “get enough”)
  • 🔴 Lights up on the dashboard Check Engine, but the scanner gives errors P0335 or P0336 (DPKV circuits)
  • 🔴 Engine won't start hot, but starts normally after cooling (typical for DPKV with thermal wear)
  • 🔴 Jerking and jerking when driving at constant speeds (for example, 2000–2500 rpm)
  • 🔴 Power drop and freezing speed at around 1000–1200 rpm after releasing the gas

On Nissan March K13 with engine HR12DE faulty DPKV may appear false immobilizer activation — the car is blocked from starting, although the key is working. This is due to the fact that the ECU receives incorrect signals about the crankshaft position and activates the protection.

⚠️ Attention: If on your March appeared P0300–P0304 (misfire) simultaneously with P0335, do not rush to change coils or spark plugs. First check the DPKV - its malfunction often provokes false omissions.

Where is the crankshaft sensor located on a Nissan March?

On all modifications Nissan March (including K12 And K13) DPKV is located in one place: on the cylinder block on the flywheel side, next to the gearbox. Exact location:

  • 📍 On engines HR12DE/HR15DE: under the intake manifold, closer to the passenger compartment (you need to remove the air filter for access)
  • 📍 On engines CR14DE (diesel): on the front of the block, under the generator

The sensor is attached one 10 mm bolt and has a two-pin connector (on some versions - three-pin with shielding). You have to dismantle it to see it. plastic engine cover and disconnect the air duct pipe.

📊 Where is your crankshaft sensor located?
  • Under the intake manifold
  • Near the generator
  • I don't know, I didn't look
  • Another option

Important: On March K13 with HR12DE The sensor may be hidden under a layer of dirt - before diagnosing, clean the area around it to avoid damaging the connector.

How to check the crankshaft sensor on a Nissan March?

Diagnosis of DPCV on Nissan March includes 4 stages: Visual inspection, resistance test, inductance test and waveform analysis. Let's look at each method in detail.

1. Visual inspection

Before using the multimeter, inspect the sensor for:

  • 🔍 Cracks or chips on the body (especially at the base)
  • 🔍 Oxidation of contacts in the connector (clean only special liquid for contacts, not sandpaper!)
  • 🔍 Traces of oil or antifreeze (leakage may shorten the chain)
  • 🔍 Play in the fastening (the gap must be fixed)

2. Resistance check

To do this:

  1. Disconnect the sensor connector.
  2. Set the multimeter to resistance measurement mode (200–2000 Ohms).
  3. Connect the probes to the sensor contacts (polarity is not important).

Normal values for Nissan March:

Engine modelDPKV resistance, OhmNote
HR12DE800–1200At 20°C
HR15DE750–1100May vary ±5%
CR14DE (diesel)500–700Sensitive to overheating

If resistance below 500 ohms or above 1500 Ohm - the sensor is faulty. Also check the circuit for an open circuit: the resistance between the contacts of the ECU connector and the sensor should be 0–1 Ohm.

3. Checking inductance (for advanced)

For this you need megohmmeter or oscilloscope. Algorithm:

Connect a megohmmeter to the sensor contacts|

Set voltage to 500V|

Measure the insulation resistance (should be >20 MΩ)|

Check inductance (normal: 200–400 mH)

-->

On Nissan March with HR15DE low inductance (less than 150 mH) often leads to error P0336 — “Low level of DPKV signal.”

4. Oscillogram (the most accurate method)

If you have access to an oscilloscope (or adapter ELM327 with graph support), connect to the signal wire of the sensor and crank the engine with the starter. Healthy waveform must have:

  • 📊 Smooth peaks of equal amplitude
  • 📊 No “dips” or noise
  • 📊 Frequency corresponding to crankshaft speed
Example of a faulty waveform

The graph shows chaotic voltage surges up to 5 V (normally no more than 0.5 V), which indicates a breakdown of the sensor insulation or damage to the master disk. Often found on March after an accident or unqualified repair.

Original and similar sensors for Nissan March

For Nissan March Sensors from different manufacturers are suitable, but original (article 23731-4M000 or 23731-4M010) guarantee compatibility with the ECU. However, their price (from 3,500 rubles) often forces owners to look for analogues.

ManufacturerArticlePrice, rub.Note
Nissan (original)23731-4M0003500–4200Best choice for HR12DE/HR15DE
HitachiEX100-10012100–2500High reliability, but sensitive to temperature changes
Bosch0 261 210 1151800–2200Suitable for diesel CR14DE
Febi216101200–1500Budget option, but resource ~50 thousand km
Blue PrintADG023031600–1900Good price/quality balance

Important: On March K13 with HR12DE It is not recommended to install sensors no-name brands (eg Sat or Master-sport) - they often fail after 10–15 thousand km due to a mismatch in magnetic characteristics.

⚠️ Attention: When purchasing an analogue, be sure to check core length - on some non-original sensors it is 1–2 mm shorter, which leads to an increase in the gap and false signals.

Step-by-step instructions for replacing the crankshaft sensor

Replacing DPKV with Nissan March takes 20–40 minutes and does not require special skills. You will need:

  • 🔧 10 mm socket (or wrench)
  • 🔧 Flat blade screwdriver (for removing connector)
  • 🔧 Feeler gauge 0.5 mm (to check the gap)
  • 🔧 WD-40 (if the bolt is stuck)

Procedure:

  1. Disable negative battery terminal (required!).
  2. Remove plastic engine cover and disconnect sensor connector (press the lock and pull up).
  3. Unscrew the sensor mounting bolt (a head extension may be required).
  4. Carefully remove the sensor by rocking it from side to side (do not pull by force!).
  5. Clean the seat from dirt and oil.
  6. Install the new sensor, making sure it is sat tight until it stops.
  7. Tighten the bolt to torque 8–10 Nm (do not overtighten!).
  8. Connect the connector and check the gap between the sensor and the drive disc (should be 0.5–1.2 mm).
💡

Before installing a new sensor, apply a little dielectric grease on the O-ring - this will prevent moisture from entering and extend service life.

After replacement:

  • 🔄 Reset ECU errors (for example, via ELM327 or by disconnecting the battery for 10 minutes).
  • 🔄 Start the engine and check the idle speed (jerks and dips should disappear).
  • 🔄 Carry out a test drive with sharp accelerations - if the errors do not return, the replacement was successful.

Common mistakes when replacing DPKV on a Nissan March

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

  • 🚫 Ignoring Gap: If the sensor is installed with a gap >1.5mm, the ECU will receive a weak signal, which will cause an error P0336.
  • 🚫 Connector damage: When disconnecting the wire, do not pull on the wires themselves - only on the plastic housing of the connector.
  • 🚫 Using sealant: Some “masters” spread sealant onto the seat, which later leads to corrosion of the contacts.
  • 🚫 Incorrect tightening torque: An overtightened bolt will deform the sensor body, and a loose bolt will cause vibration.
💡

On Nissan March with HR12DE engine strictly prohibited use sensors from other Nissan models (for example, from Note or Juke), even if they are externally identical. Differences in magnetic characteristics will result in unstable motor operation.

Another common mistake is failure to check the power supply. If the error remains after replacing the sensor, measure the voltage at the ECU connector (pin 1 — +12 V, contact 2 - mass). No power indicates a broken wire or a faulty ECU.

How long does the crankshaft sensor last on a Nissan March?

DPKV resource for Nissan March depends on operating conditions:

  • 📅 Original sensor: 100–150 thousand km (in the absence of mechanical damage).
  • 📅 High-quality analogue (Hitachi, Bosch): 60–80 thousand km.
  • 📅 Budget analogue (Febi, Blue Print): 30–50 thousand km.

Factors that reduce service life:

  • 🔥 Engine overheating (especially at CR14DE)
  • 💧 Oil or antifreeze gets on the connector
  • 🛠️ Impacts to the sensor during repairs (for example, when replacing the clutch)
  • ⚡ Voltage surges in the on-board network (faulty generator)

How to extend the life of DPKV?

Regularly clean the connector from oxidation|

Check oil level (leaks destroy insulation)|

Avoid high pressure engine washing|

Check the clearance at every maintenance (especially after repairs)

FAQ: Frequently asked questions about the crankshaft sensor on Nissan March

Is it possible to drive with a faulty DPKV?

No. The crankshaft sensor is the only sensor without which the engine Nissan March won't start. In rare cases, the engine may start, but will run intermittently and stall. Driving for a long time with a faulty DPKV will damage the ignition coils and fuel injectors.

Why doesn't P0335 go away after replacing the sensor?

There are several reasons:

  1. Faulty wiring between the sensor and the ECU (check the circuit).
  2. Damaged master disk on the crankshaft (teeth chipped or dirty).
  3. Incorrect gap between the sensor and the disk (should be 0.5–1.2 mm).
  4. The new sensor is defective (check the resistance).
Which sensor is better to choose for Nissan March K13 with HR12DE engine?

Optimal options:

  1. Original (23731-4M000) - if the budget allows.
  2. Hitachi EX100-1001 - the best analogue in terms of reliability.
  3. Bosch 0 261 210 115 — if you need compatibility with diesel versions.

Avoid cheap Chinese sensors - they often trigger falsely at low temperatures.

Is it possible to clean the crankshaft sensor if it is dirty?

Cleaning is possible, but not always effective. Algorithm:

  1. Remove the sensor and wipe the housing lint-free cloth, soaked in isopropyl alcohol.
  2. Clean the connector pins special liquid (For example, CRC Contact Cleaner).
  3. Blow with compressed air (do not use a compressor - only a can).

If after cleaning the sensor resistance is not normal, it needs to be replaced.

What happens if the crankshaft sensor is installed incorrectly?

Consequences:

  • 🚗 Engine won't start or will work intermittently.
  • 🚗 Errors will appear P0335, P0336, P0325 (open circuit).
  • 🚗 Possible mechanical damage sensor or drive disk.

The most common mistake is reversed polarity when connecting the connector (although on most sensors the contacts are symmetrical).
