Parts for your 2021 Mitsubishi Outlander-Camshaft sensor

2021 Mitsubishi Outlander camshaft sensor — purpose, servicing and when to replace

Yes, the 2021 Mitsubishi Outlander uses a camshaft position sensor. This is confirmed by Mitsubishi Motors factory service information for the GF/GG platform (Engine Electrical section – Camshaft Position Sensor/PHASE), the Mitsubishi ASA electronic parts catalogue listing a CMP sensor for 2021 petrol and PHEV variants, and well-known workshop databases such as Autodata and Mitchell 1/ALLDATA, which show the CMP feeding the ECM for MIVEC (variable valve timing), sequential fuel injection and ignition timing.

The camshaft sensor on a 2021 Mitsubishi Outlander tells the engine computer exactly where the cam is in its rotation. Paired with the crank sensor, it lets the ECM fire the injectors and spark at the right moment and tweak MIVEC timing for smooth idle, decent punch off the line, and better fuel economy. If it goes out of whack, the Outlander can be a pig to start, stumble at idle, hesitate on take-off, and light the check engine lamp. Common fault codes include P0340 and P0341.

There’s no scheduled replacement interval for the camshaft sensor, it’s a “fit and forget” item. As part of regular servicing, it’s smart to:

• Visually check the sensor connector and harness for oil intrusion, corrosion, or damage.
• Keep the area around the rocker cover dry — fix any oil leaks that could soak the sensor.
• If the battery’s been low or the engine has been jump-started, scan for stored cam/crank correlation codes.

When replacement is needed, it’s straightforward on the 2.4‑litre petrol and PHEV. Access is typically from the top of the engine near the timing cover on the cylinder head. Use an OEM or high-quality aftermarket sensor, fit a fresh O‑ring if applicable, and tighten the retaining bolt to factory spec. After installation, clear codes and perform an idle relearn if prompted by your scan tool. If the Outlander has been cutting out or going into limp mode, avoid driving it until it’s fixed — losing cam signal can make the engine stall, which is no fun in busy traffic.

A quick scan, a clean connector, and the right replacement part usually has a 2021 Outlander back to its easy-going best under the bonnet.

• Popular questions about the 2021 Mitsubishi Outlander camshaft sensor

Where is the camshaft sensor on a 2021 Mitsubishi Outlander?
On the 2.4‑litre petrol and PHEV, it’s mounted on the cylinder head near the timing cover. Access is generally from the top once the engine cover and, if needed, the intake duct are out of the way. The connector is easy to spot running to the front side of the head.

What fault codes point to a bad camshaft sensor on this model?
Common codes are P0340 (Camshaft Position Sensor Circuit) and P0341 (Camshaft Position Sensor Range/Performance). You might also see misfire or VVT/MIVEC timing codes when the ECM can’t reliably sync cam and crank signals.

Does the camshaft sensor need routine replacement?
No set interval. It’s replaced on condition. During normal services, a quick visual check of the wiring and a scan for stored cam/crank correlation faults is all that’s usually required. Replace the sensor if there are drivability symptoms or confirmed DTCs.
