Parts for your 2006 Mitsubishi Pajero-Camshaft sensor

2006 Mitsubishi Pajero camshaft sensor — what it does and when to sort it

Technical sources confirm the 2006 Mitsubishi Pajero does use a camshaft position sensor (CMP). The Mitsubishi Pajero/Montero Workshop Manual (Engine Electrical section, 2003–2006 coverage), the Mitsubishi ASA parts catalogue, and professional repair databases such as Autodata/Mitchell list a CMP for the 3.2 DI‑D (4M41) and the 3.8 V6 (6G75). The V6 in particular uses one sensor per bank, while the 4M41 diesel uses a single CMP to identify cylinder phase for precise fuel injection.

On a 2006 Pajero, the camshaft sensor tells the ECU exactly where the cam(s) are in relation to the crank, so it can fire injectors sequentially, time ignition correctly on petrol models, and manage features like MIVEC on the 6G75. When the sensor starts to fail, owners often notice long cranking, rough idle, misfires on cold start, a flat spot under load, or the odd stall. The check engine light commonly flags codes like P0340/P0341. Left alone, the ECU may fall back to a limp strategy using the crank signal, but drivability and fuel economy take a hit.

Replacement isn’t a big drama for most home wrenchers, but a quick check first can save cash. Inspect the connector for oil intrusion or green corrosion, make sure the harness isn’t rubbing on the cam cover, and verify the air gap/seat is clean. If fitting a new sensor, lightly oil the O‑ring, seat it square, and tighten the retaining bolt to the workshop spec (typically around 8–10 Nm for the small CMP fastener). On the 6G75 V6, don’t mix up left and right bank sensors, they look similar but are bank‑specific. On the diesel 4M41, the CMP is usually up front near the cam gear cover, on the V6, each sensor sits at the end of its respective cam cover.

There’s no fixed replacement interval, these are usually “replace on condition”. As part of normal servicing, it’s smart to:

• Scan for stored CMP‑related fault codes if cranking time increases or idle turns lumpy.
• Keep connectors dry and secure, avoid blasting the area with a pressure washer.
• On V6 timing belt services, inspect both CMPs and their wiring while the front end is accessible.

Use quality, OE‑spec parts for reliable hot‑start behaviour and correct synchronisation. A good scan tool and the Pajero workshop manual procedures will help confirm a clean fix.

Popular questions

Where is the camshaft sensor on a 2006 Pajero?
On the 3.2 DI‑D (4M41) diesel, it’s typically mounted at the front of the cylinder head near the cam drive. On the 3.8 V6 (6G75), there are two—one on each bank—mounted near the ends of the cam covers. Access varies by market trim and intake layout, but they’re reachable with basic hand tools.

Can you drive with a failing camshaft sensor?
You might get home, but it’s not ideal. The ECU can sometimes run a fallback strategy off the crank sensor, which may mean long cranks, reduced power and higher fuel use. If it’s stalling or logging codes like P0340/P0341, sort the fault promptly to avoid being stranded.

Do diesel and petrol Pajero models use the same sensor?
No. The 4M41 diesel uses a single CMP designed for that engine, while the 6G75 petrol V6 uses two bank‑specific sensors. Part numbers, connector keys and calibration can differ, so match the sensor to the engine and VIN.
