Parts for your 2022 Mitsubishi Asx-Crank angle sensor

2022 Mitsubishi ASX crank angle sensor (crankshaft position sensor)

Based on technical references such as the Mitsubishi Motors Service Manual for ASX/RVR/Outlander Sport (4B11/4B12 MIVEC engines), Autodata 2022, and the Mitsubishi ASA electronic parts catalogue, the 2022 Mitsubishi ASX is fitted with a crankshaft position sensor—often called a crank angle sensor. It’s a primary engine management input and is absolutely used on this model.

This sensor tracks crankshaft speed and exact angular position, feeding the ECU the timing it needs for spark, fuel injection, VVT/MIVEC control, misfire monitoring, and the rev limiter. If the signal drops out, the ASX may not start, may stall unexpectedly, or run in a severely limited state.

There’s no scheduled replacement interval for the crank angle sensor, but it pays to show it some love during regular servicing. A quick once-over can save a no-start drama when you’re miles from home.

• Run a scan-tool health check for DTCs such as P0335–P0339 and confirm the ECU reads stable engine RPM during cranking and idle.
• Inspect the connector and loom routing at the front of the engine for oil contamination, heat damage, or chafing near the auxiliary belt and RH splash shield.
• Wipe any metallic fuzz from the sensor tip and address oil leaks from the front crank seal that can wick into the plug.
• Verify battery voltage and engine grounds, low system voltage can mimic a failing sensor.

Symptoms that point to a tired crank angle sensor include long cranks, random cut-outs when hot, rough idle, misfire under load, and the tacho unexpectedly dropping to zero. Heat-soak faults are common: the car won’t restart hot but comes good after cooling down. A scope capture of the crank waveform (and its sync to the cam sensor) is the best test, though many workshops make the call using scan data and fault codes.

Replacement is straightforward: disconnect the battery, raise and support the front, remove the right-hand splash shield, unplug the sensor, remove its single retaining bolt, swap the sensor and O-ring, then refit. Tighten to the manufacturer’s spec, clear codes, and perform a road test. Most workshops book 0.5–1.0 hour. Stick with an OE-quality sensor—cheap units can introduce signal noise that confuses the ECU.

The ASX uses both crank and cam sensors for full sequential control. Location and plug style can vary slightly between the 2.0L and 2.4L MIVEC engines, but the function is identical.

Does the 2022 ASX have a crank angle sensor or only a cam sensor?

It has both. The crank angle sensor (crankshaft position sensor) provides engine speed and exact crank angle, while the cam sensor confirms valve timing. The ECU needs the pair for precise ignition and fuel control. On the 2022 ASX, the crank sensor is mounted at the front of the engine, reading a toothed wheel on the crank.

What are the common signs or fault codes for a bad crank angle sensor on an ASX?

Typical symptoms are a no-start, hot-stall then restart when cooled, rough idle, hesitation, and a dead tacho during crank. Common fault codes include P0335 (crankshaft position sensor “A” circuit) and P0336 (range/performance). Heat and oil contamination are usual culprits.

Can it be replaced at home, and what might it cost in Australia or NZ?

DIY is doable with basic tools, stands/ramps, and care. Expect to remove the RH splash shield for access. In Australia or New Zealand, quality sensors generally run $150–$350, with labour at a workshop typically $150–$300 depending on rates and engine variant. Always confirm torque specs in a current service manual.
