Parts for your 2022 Mitsubishi Asx-Camshaft sensor

2022 Mitsubishi ASX camshaft sensor — what it does and how to look after it

Yes, the 2022 Mitsubishi ASX is fitted with a camshaft position sensor. This isn’t optional kit, it’s part of the engine management on the 2.0L DOHC MIVEC petrol used in AU/NZ models. Mitsubishi technical literature for RVR/ASX/Outlander Sport (2019–2022) in the Engine Electrical section details the camshaft position sensor and related diagnostics (e.g., DTCs P0340 and P0341), and the service manual wiring diagrams show the sensor’s 5V supply, ground and signal to the ECM. Parts catalogues for the same platform also list a dedicated camshaft position sensor and O-ring.

The camshaft sensor’s job is to tell the engine control module exactly where the intake cam is. That lets the ECU synchronise sequential fuel injection, sharpen ignition timing, and command the MIVEC cam phasing for smooth torque and good fuel economy. If the sensor signal drops out, the ASX may still run on crank sensor fallback, but it’ll usually crank longer, feel doughy, and throw a check engine light.

There’s no routine replacement interval for this sensor, it’s a fit-and-forget item unless it faults. Smart servicing is about prevention and quick diagnosis:

• Keep the connector clean and clipped firmly, check for brittle conduit or rubbing near the front of the head/timing cover during regular services.
• Watch for symptoms: hard starting, rough idle, random stalling, flat spots, poor fuel economy, and fault codes P0340/P0341.
• Rule out basics first — oil contamination in the plug, damaged wiring, or low battery voltage can mimic a failed sensor.

When replacement is needed, it’s a straightforward job for a tech:

1. Confirm with a scan tool that the cam signal is missing or erratic and that the 5V reference and ground are present.
2. Disconnect the battery, remove the engine cover, and locate the sensor at the front/top of the cylinder head.
3. Undo the small retaining bolt, withdraw the sensor, and swap in a quality unit with a fresh O-ring lightly oiled for installation.
4. Refit, tighten the bolt to workshop-spec torque, reconnect, clear codes, and road test. The ECU will relearn quickly after a short drive.

Genuine or reputable aftermarket parts are recommended. If a light returns, check the timing correlation and wiring rather than throwing more parts at it. Sorted, the ASX goes back to easy starts and tidy fuel numbers.

Popular questions about the 2022 Mitsubishi ASX camshaft sensor

Where is the camshaft sensor on a 2022 ASX?
It’s mounted on the cylinder head at the front of the engine, near the timing cover area. Pop off the engine cover and it’s accessible from above. Look for a small sensor body with a single bolt and a three-pin connector.

What fault codes point to a bad camshaft sensor?
Common codes are P0340 (Camshaft Position Sensor Circuit) and P0341 (Camshaft Position Sensor Range/Performance). Before replacing the sensor, check the connector for oil or corrosion and verify the 5V supply, ground, and signal integrity.

Can the ASX be driven with a faulty camshaft sensor?
Usually it will start and run, but with longer cranking, reduced performance, and a check engine light. It’s best not to keep driving like that, book it in to prevent rough running and potential stalling at awkward moments.
