Parts for your 2015 Mitsubishi Asx-Crank angle sensor

2015 Mitsubishi ASX crank-angle sensor: fitted, essential, and worth looking after

Technical sources confirm the 2015 Mitsubishi ASX uses a crank-angle sensor (commonly called a crankshaft position sensor, CKP). The Mitsubishi Motors ASX/Outlander Sport/RVR workshop manual for 2010–2016 (Engine and Engine Electrical sections, including DTC P0335/P0336) describes the CKP signal as critical for engine control. The Mitsubishi ASA electronic parts catalogue for GA-series ASX also lists a crankshaft position sensor for both the 2.0L 4B11 petrol and the 1.8L 4N13 diesel variants. These sources verify that a CKP/crank-angle sensor is fitted and required for timing and injection on the 2015 ASX.

On a 2015 ASX, the crank-angle sensor tracks the exact position and speed of the crankshaft, feeding this to the engine control unit (ECU). That signal lets the ECU fire the spark, time the fuel injection, manage variable valve timing, and monitor misfire. If the signal drops out, the engine may crank but won’t start, or it can stall and run roughly. It’s the heartbeat the ECU listens to every time the key’s turned.

It’s not a routine “replace at X km” service item in Australia or New Zealand, but it’s smart to keep an eye on it during scheduled servicing. A quick visual under the bonnet for damaged wiring, oil contamination at the sensor plug, or loose connectors helps prevent intermittent faults. If the check engine light pops up with codes like P0335/P0336, or there’s hard starting after rain or washing, the sensor or its wiring deserves attention.

• Typical symptoms when the CKP is failing:
  • Long crank or no-start
  • Random stalling or misfiring under load
  • Tacho dropouts, poor economy, limp-home behaviour
  • ECU fault codes P0335/P0336

Replacement is straightforward for a trained tech: battery safeing, disconnect the plug, remove the retaining bolt, swap the sensor (with a fresh O-ring if specified), refit to the correct depth, then clear codes and road-test. Always use a quality OEM-equivalent part, cheap copies can give a weak signal and chase-your-tail faults. Most ECUs on ASX self-learn the signal, though an idle relearn and a cam/crank correlation check with a scan tool are good practice. Time-on-tool is usually short, but access differs by engine and drivetrain, so workshop guidance by VIN is best.

For high-kilometre ASX vehicles, heat and vibration are the usual culprits, so preventive checks of the harness routing and connector seal can save the day. If in doubt, a proper diagnostic scope trace of the CKP waveform beats guessing.

Where is the crank-angle sensor on a 2015 ASX?

It’s mounted to the engine so it can read a toothed reluctor on the crankshaft. On both petrol (4B11) and diesel (4N13) variants it’s typically on the block near the crank, accessed from the front or side depending on layout. Exact placement varies by engine and market spec, so a workshop manual or parts diagram by VIN is the best guide.

Can a bad crank-angle sensor cause a no-start?

Yes. If the ECU can’t see crank position, it can’t time spark or fuel. The result is long cranking or a dead no-start, sometimes after intermittent stalling. A scan for P0335/P0336 and inspection of the sensor plug and wiring will usually point you in the right direction.

Does the ASX need a relearn after CKP replacement?

Most 2015 ASX models self-adapt the new sensor. It’s still wise to clear fault codes, perform an idle relearn if required, and check cam/crank correlation with a scan tool. If correlation codes persist, follow the relearn or timing-check procedure in the service information.
