Parts for your 2017 Mitsubishi Outlander-Camshaft sensor

2017 Mitsubishi Outlander Camshaft Sensor — What it does, and when to replace it

Yes, the 2017 Mitsubishi Outlander is fitted with a camshaft position sensor (often called a cam sensor). This is confirmed in Mitsubishi Motors factory service documentation: the Outlander (GF/GP series) petrol 2.0/2.4‑litre engines and the PHEV list a camshaft position sensor in Group 13A – Engine Electrical diagnostics (DTCs P0340/P0341), the 3.0‑litre 6B31 V6 uses two sensors (one per bank), and the 2.2‑litre turbo‑diesel also specifies a camshaft phase sensor in its engine management section. These references appear throughout the Mitsubishi Outlander 2014–2019 Service Manual and the Outlander PHEV Workshop Manual under Camshaft Position Sensor diagnostics and replacement procedures.

On a 2017 Outlander, the camshaft sensor tells the engine computer exactly where the cam(s) are in their rotation. That live timing info lets the ECU sync fuel injection and ignition, control MIVEC variable valve timing, and get the engine firing cleanly from the first crank. If the signal goes missing or drifts, starting can take longer, idle can get lumpy, and the ECU may park the car in limp mode to protect the engine. The V6 needs one sensor per bank, while the four‑cylinder petrol and PHEV have a single sensor mounted on the cylinder head. Either way, it’s a small part doing a big job.

It’s not a scheduled replacement item in Australia or New Zealand, but it’s smart to give it a look during major services — especially on higher‑kilometre Outlanders. Under the bonnet, check the connector and harness for brittle insulation, oil wicking into the plug, or damage from heat. Keep engine oil changes on time, clean oil helps prevent sludge that can interfere with the sensor’s magnetic pickup and the cam trigger wheel.

Typical signs it’s time to test or replace the cam sensor include:

• Hard starting, extended cranking, or stalling after start
• Rough idle, flat spots, or poor fuel economy
• Check engine light with codes like P0340/P0341 (and P0365/P0366 on V6)

Replacement is straightforward: disconnect the battery negative, unplug the sensor, remove the retaining bolt, twist and lift the sensor out, renew the O‑ring, and refit, tightening to factory spec. Use a quality OEM‑equivalent sensor and the correct bank‑specific part on the V6. After installation, clear fault codes and, if applicable, perform an idle or cam/crank relearn with a scan tool. Access on the four‑cylinders is typically quick, the V6 can take longer due to space. Done right, it’s a tidy fix that restores smooth starting and proper MIVEC behaviour.

Where is the camshaft sensor on a 2017 Outlander?
The four‑cylinder petrol and PHEV usually have the sensor on the cylinder head near the cam gears. The 3.0‑litre V6 uses two sensors, one on each bank. Exact spots vary slightly by engine code, so a quick glance at the service manual or an under‑bonnet label helps.

Will a failing cam sensor damage the engine?
It generally won’t cause immediate mechanical damage, but it can trigger misfires, rough running, and stalling. Left unchecked, poor combustion can stress the catalytic converter. Best to diagnose and replace promptly if faults appear.

Do camshaft sensors need routine replacement?
No fixed interval applies. They’re replaced on condition. During major services, check wiring and connectors, keep oil fresh, and only swap the sensor if there are symptoms or confirmed fault codes.
