Parts for your 2003 Mitsubishi Pajero-Crank angle sensor

2003 Mitsubishi Pajero crank-angle-sensor: what it does, where it is, and how to look after it

Based on Mitsubishi’s NM/NP Pajero Workshop Manual (2000–2006), the Mitsubishi ASA parts catalogue, and common service data (Autodata and Bosch ESI[tronic]), the 2003 Mitsubishi Pajero is fitted with a crank-angle-sensor (often listed as a crankshaft position sensor, CKP). This applies across the popular 3.5L 6G74 and 3.8L 6G75 V6 petrol engines, as well as the 3.2L 4M41 Di‑D diesel. So yes, the crank-angle-sensor is relevant on this model.

The crank-angle-sensor is the engine’s timekeeper. It reads a toothed wheel on the crankshaft and feeds exact crank position and speed back to the ECU. With that, the ECU decides when to fire the spark (petrol) or control injection timing (diesel). If the signal drops out or goes flaky, the Pajero can be hard to start, misfire, run roughly, or stall at idle. Fault codes like P0335/P0336 are common flags.

On the 2003 Pajero, the sensor is mounted close to the crank—typically at the front timing cover near the crank pulley on the V6s, and either at the timing case or bellhousing area on the 3.2 Di‑D—so it can read the trigger wheel accurately.

It’s not a scheduled replacement item, but it benefits from sensible care:

• Keep connectors clean and locked, heat and oil can make terminals brittle.
• Watch for oil leaks from the front cover or crank seal that can contaminate the sensor face.
• If doing timing belt work on V6 models, be mindful of the sensor wiring and the trigger wheel—bent teeth or poor gap will upset the signal.

When replacement is needed, quality matters. A genuine or reputable OEM-equivalent sensor avoids dodgy signals that cheaper units can produce. Fit a new O‑ring if specified, route the loom exactly as per the manual to avoid heat soak, and torque the retaining bolt correctly. Most Pajeros won’t need coding after a CKP swap, but clearing fault codes and performing an idle relearn is good practice. If the engine still cranks without starting after replacement, recheck the air gap (where adjustable), connector seating, and the trigger wheel for damage. For exact specs and torque values, the Mitsubishi workshop manual should be followed.

Typical warning signs owners report include long cranking when hot, random stalling at the lights, dead tachometer during crank, and a no-start with P0335 stored. Catching those early can save a tow and keep the Pajero happy on Kiwi and Aussie roads.

Popular questions

Where is the crank-angle-sensor on a 2003 Mitsubishi Pajero?

On most V6 petrol models (6G74/6G75), it’s mounted at the front of the engine near the crank pulley behind the timing cover. On the 3.2 Di‑D (4M41), it’s positioned to read the crank trigger at the timing case or near the bellhousing area. Access varies by engine and trim, so checking the workshop manual helps before diving in.

What are the symptoms of a failing crank-angle-sensor?

Common signs include intermittent no-start, stalling when hot, rough running, misfire, a dead or shaky tacho during cranking, and MIL on with codes like P0335/P0336. The ECU can’t time spark/injection properly without a clean crank signal, so the engine may crank strongly but refuse to fire.

Does a new crank-angle-sensor need programming?

Generally, no programming is required on the 2003 Pajero. After installation, it’s wise to clear stored faults and perform an idle relearn. If issues persist, verify the sensor gap (if adjustable), correct mounting, and the condition of the trigger wheel and wiring.
