Parts for your 2004 Mitsubishi Pajero-Crank angle sensor

2004 Mitsubishi Pajero crank angle sensor — what it is, where it lives, and how to look after it

Yes, the 2004 Mitsubishi Pajero does use a crank angle sensor (also called a crankshaft position sensor/CKP). This applies to both the 3.2 Di‑D 4M41 diesel and the petrol V6 used in this era. Technical references backing this up include the Mitsubishi Pajero/Montero NM–NP Series Workshop Manual (Engine and Engine Electrical sections, 2003–2006), which details the CKP input for engine timing and injection control, the Mitsubishi ASA electronic parts catalogue for 2004 VINs, which lists a crank angle/CKP sensor for the 4M41 and 6G75 engines, and Bosch common‑rail documentation noting the CKP as essential for ECU synchronisation on CRD systems.

On this Pajero, the crank angle sensor feeds the ECU precise crankshaft speed and position so it can time fuel injection and ignition bang on the money. On the 4M41 diesel it’s fitted at the front timing case near the crank sprocket, on the petrol V6 it’s typically mounted near the bellhousing or timing cover (model and market dependent). Without a clean signal, expect hard starting, random stalling, a dead tacho while cranking, or limp‑home behaviour, often tagged by fault codes like P0335/P0336.

While the CKP isn’t a scheduled “service item”, it’s smart to give it some love during routine servicing:

• Scan for stored codes and crank/cam sync issues, especially after rough starting.
• Inspect the connector for green crusties, broken locks, or oil wicking through the loom.
• Check for oil leaks at the front cover/rear main area that could contaminate the sensor.
• Look for damaged wiring near engine mounts where looms can rub through.
• If removed, clean the magnetic tip carefully and refit with a fresh O‑ring, torqued to spec from the workshop manual.

Replacement is straightforward for most home spanner‑turners: disconnect the battery, unplug the sensor, remove the retaining bolt, twist and pull the sensor free, lightly oil the new O‑ring, and refit. No coding is usually required, clear any codes and the ECU will relearn on the next start. If issues persist, check the cam sensor and timing, as a crook CKP signal can be a symptom of bigger mechanical timing problems.

Quality matters here. Cheap no‑name sensors can cause hot‑soak no‑starts and intermittent faults that’ll drive anyone spare. A reputable OEM‑equivalent sensor and a tidy harness are the go for reliable touring across Aussie and Kiwi kilometres.

Where is the crank angle sensor on a 2004 Pajero?

On the 3.2 Di‑D 4M41 diesel it’s mounted at the front timing case near the crankshaft gear. On the petrol V6 of this era it’s commonly at the rear of the block near the bellhousing or at the front timing cover, depending on exact variant. Access is usually from below with the splash shield off.

What are the common symptoms and fault codes when the CKP fails?

Hard or no start, random stalling, misfire at low rpm, the tacho dropping to zero while cranking, and limp mode are typical. The ECU often logs P0335 (Crankshaft Position Sensor “A” Circuit) or P0336 (Range/Performance).

Can the sensor be cleaned, or should it be replaced?

If the tip just has light metallic fuzz, a careful clean can restore the signal. If there’s internal failure, heat‑soak faults, damaged wiring, or oil intrusion past the seal, replacement is the fix. Always inspect and tidy the loom and connector to prevent repeat issues.
