Parts for your 2005 Mitsubishi Pajero-Camshaft sensor

2005 Mitsubishi Pajero Camshaft Sensor

Yes — the 2005 Mitsubishi Pajero is fitted with a camshaft position sensor (CMP). This applies to both the 3.2 Di‑D 4M41 diesel and the 3.8 V6 6G75 petrol variants. Technical sources include the Mitsubishi Motors factory workshop manual for the NM/NP series (2000–2006, Engine Control section) and the Mitsubishi ASA (Aftersales Service) parts catalogue, both of which list and detail a CMP sensor and its role in engine control strategy.

The camshaft sensor’s job is to tell the ECU exactly where the camshaft is in its rotation, so the ECU can sync fuel injection (and ignition on petrol models) to the correct stroke. That accurate timing helps cold starts, smooth idle, cleaner emissions and decent fuel economy. On the diesel 4M41, the CMP works with the crank sensor to manage injection timing and misfire detection, on the V6 6G75 it also supports sequential injection and spark timing.

Owners who are seeing hard starting, random stalling, rough idle, a noticeable flat spot, or a lit MIL may be dealing with a tired CMP. Common scan codes include P0340 and P0341. Before parts swapping, it’s smart to check the basics: wiring plugs under the bonnet for corrosion or oil ingress, harness chafing near the rocker cover, and correct battery voltage. A quick oscilloscope or scan-data check (cam/crank sync) can save a lot of guessing.

Replacement is straightforward for most home mechanics. Disconnect the battery, locate the sensor on the cylinder head/timing cover area (bank end on the V6, upper timing case region on the 4M41), unplug the connector, remove the retaining fastener, and lift the sensor out. Lightly oil the new O‑ring, seat the new sensor, refit the bolt, and reconnect. Always follow the workshop manual for exact torque and routing, and clear codes with a scan tool. A brief road test to confirm stable cam/crank synchronisation and no return of fault codes is good practice.

There’s no periodic service interval for the CMP itself, but as part of regular servicing it’s worth inspecting the connector seals, confirming the loom is clipped away from heat and sharp edges, and ensuring any oil leaks from rocker covers are sorted so they don’t wick into the plug. Quality OEM or reputable aftermarket sensors usually offer the best reliability per dollar for Aussie and Kiwi conditions.

• Typical symptoms: long crank, misfire at idle, poor fuel economy, limp mode, MIL on
• Handy checks: scan for P0340/P0341, inspect connector/loom, verify cam/crank sync

FAQs

Where is the camshaft sensor on a 2005 Pajero?
On the 3.2 Di‑D 4M41 it’s mounted near the upper timing case/cam area on the cylinder head. On the 3.8 V6 6G75 it’s positioned at the end of a cylinder head near the cam gear. Access is under the bonnet without removing major components on most trims.

Can a faulty camshaft sensor cause hard starts and stalling?
It can. If the ECU can’t see a clean cam signal, it may struggle to sync injection and ignition properly, causing long crank, random stalls, and rough idle. A scan showing P0340/P0341 and poor cam/crank correlation is a strong pointer.

Should the camshaft sensor be cleaned or replaced?
If the connector is dirty or oily, clean it and recheck. The sensor itself is a solid-state unit, if the signal is weak or erratic, replacement is the usual fix. Always rule out wiring faults before fitting a new sensor.
