Parts for your 1995 Mitsubishi Pajero-Crank angle sensor

1995 Mitsubishi Pajero crank-angle sensor: what it does and how to look after it

Yes, a crank-angle sensor is relevant to the 1995 Mitsubishi Pajero. On the 3.0L/3.5L petrol models (6G72/6G74), Mitsubishi locates the crank-angle sensing function inside the distributor as an optical/Hall pick-up (often described in the manual as a cam/crank angle sensor). On 2.8L 4M40 diesels fitted with the electronic injection pump (EDC), there’s a separate crankshaft position/angle sensor at the front timing case. Base 4M40 models with purely mechanical pumps may not use a stand-alone crank sensor. This layout is documented by the Mitsubishi Pajero/Montero Factory Service Manual 1991–1996 (Engine Group 13A for 6G7x ignition, Diesel Group 13D for 4M40), the Mitsubishi ASA/CAPS parts catalogue (listing “Crankshaft Position Sensor” for applicable VIN ranges), and third‑party references such as Haynes Pajero/Montero 1983–1997 and Autodata ignition/injection specs for MY95.

For petrol Pajeros, the crank-angle sensor inside the distributor is the timing heartbeat. It tells the ECU/ignition module exactly where the crank is so spark can be fired at the right moment. On 4M40 EDC diesels, the sensor feeds engine speed/position to the pump ECU so injection timing lands on the money and the tacho behaves. If it drops out, the Pajero may be a no-start, stall at idle, misfire when hot, or set a fault light on later variants.

There’s no set replacement interval, but it’s smart to check the sensor and its wiring during major services (100,000 km-ish) or whenever there are hard starts or random cut-outs. On petrol models, pop the distributor cap and look for oil ingress, cracked pick-ups, or brittle wiring to the internal sensor. Lightly clean optical windows with electronics cleaner and a lint-free swab—never abrasive. If the pick-up is toast, many owners replace the whole distributor with a quality unit, when done, set base timing with a timing light per the factory procedure.

On 4M40 EDC diesels, the stand-alone crank sensor sits by the crank pulley/timing case. Check the harness where it passes the fan and belts, confirm the mounting bolt is tight, and ensure the air gap to the trigger wheel is to spec. If there’s metal fuzz on the sensor tip, clean it, if the plastic nose is cracked or swollen, replace it. Always clear codes and verify sync on a scan tool after refit. Use OE or reputable aftermarket parts—cheap sensors often cause intermittent grief that’s hard to chase under the bonnet.

Where is the crank-angle sensor on a 1995 Pajero?

On petrol V6s it’s built into the distributor, acting as the engine’s position/speed pick-up. On 4M40 diesels with the electronic pump, it’s a separate sensor mounted at the front timing case near the crank pulley. Mechanical-pump 4M40s typically don’t have a stand-alone crank sensor.

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

Intermittent no-start, sudden stalling, misfires (often when hot), rough idle, poor fuel economy, or a check engine light on later-spec vehicles. Tachometer flicker or dropouts can also point to it.

Can it be cleaned or does it need replacement?

Minor cleaning helps if it’s just dust or metal fuzz. Optical pick-ups can be gently cleaned, magnetic sensors can be wiped to remove debris. Cracked housings, oil-soaked internals, damaged wiring, or erratic signals under heat usually call for replacement and a fresh connector pigtail if needed.
