Parts for your 1996 Mitsubishi Pajero-Camshaft sensor

1996 Mitsubishi Pajero camshaft sensor: what’s fitted and what to do

For a 1996 Mitsubishi Pajero, whether a camshaft sensor is actually used depends on the engine fitted. Technical references including the Mitsubishi Pajero factory service manuals for NH–NJ/NK series and the Gregory’s/Haynes workshop guides note that the petrol V6 engines (6G72 3.0L SOHC and many 6G74 3.5L variants) do use a camshaft position signal. On these petrol models, the signal typically comes from a cam angle sensor integrated inside the distributor, and on some DOHC versions it’s a separate sensor on the cam cover. By contrast, the 2.8L turbo‑diesel (4M40) of the same era does not use a separate, head‑mounted camshaft position sensor, engine position and timing are managed by a crank angle/TDC signal and the timing sensor within the Zexel electronic injection pump, as documented in the 4M40 engine control section of Mitsubishi’s diesel workshop materials and reflected in Mitsubishi ASA (electronic parts catalogue) listings where no stand‑alone camshaft sensor appears for 4M40.

If your 1996 Pajero is petrol‑powered, it’s running a camshaft position signal and here’s what that means for ownership and servicing.

The camshaft sensor on a petrol ’96 Pajero tells the ECU which stroke each cylinder is on so it can fire the injectors and ignition in the right order. On most Aussie and NZ‑delivered 6G72 V6s it’s built into the distributor, and on some 6G74 DOHC setups it’s a small sensor at the cam cover. When the sensor starts to go flaky, you’ll often see hard starting when hot, random stalling at idle, uneven running off‑the‑mark, or the check‑engine light with a cam signal fault (commonly P0340/P0341 on OBD‑II equipped models or an equivalent MUT code). Left alone, a dying sensor can cause no‑start headaches and chew through fuel.

There’s no scheduled replacement interval, but it’s smart to give it attention during major services—especially if you’re already under the bonnet doing plugs, leads, or a timing belt. For distributor‑type setups, inspect the plug and wiring for brittle insulation, oil contamination inside the cap, or corroded terminals. Oil leaks from the rocker covers can track into the sensor housing, so fix those first. For external cam sensors, check the o‑ring and mounting area for weeping—oil and grime can interfere with the signal.

Replacement is straightforward with basic tools. Always disconnect the battery, and if you’re removing the distributor on a 6G72, mark its position against the housing so timing isn’t nudged out when it goes back in. Use a dab of dielectric grease on the connector, route the loom away from heat, and clear any old fault codes after a road test. A known‑good aftermarket or genuine‑spec sensor usually restores crisp starts and smooth low‑speed manners. If faults persist, confirm crank sensor health and base timing, as the ECU needs both signals to play nicely.

• Typical symptoms: hard start, intermittent stall, rough idle, poor economy, stored cam sensor fault.
• Basic checks: connector condition, oil contamination, loom chafe near the rear bank and distributor.
• Good practice: fix oil leaks, replace suspect o‑rings, and verify timing marks if the distributor was moved.

Key technical sources: Mitsubishi Pajero factory service manuals (NH–NJ/NK, Engine Electrical: 6G7 series, Diesel 4M40 Engine Control), and Mitsubishi ASA electronic parts catalogue confirming a separate cam sensor is used on petrol variants and not listed for the 4M40 diesel.

FAQs

Does a 1996 Mitsubishi Pajero have a camshaft sensor?
Petrol V6 models (6G72/6G74) do—either integrated in the distributor or mounted at the cam cover on some DOHC engines. The 2.8L 4M40 turbo‑diesel doesn’t use a separate camshaft sensor, it relies on a crank/TDC signal and the timing sensor inside the electronic injection pump.

Where is the camshaft sensor on a 1996 Pajero?
On most petrol 6G72s it’s inside the distributor assembly. On certain 6G74 DOHC engines it’s a small sensor at the cam cover near a cam sprocket. Diesel 4M40 models won’t have a separate cam sensor to find.

What fault codes point to a bad camshaft sensor?
Commonly P0340 or P0341 on OBD‑II equipped vehicles, or the equivalent MUT diagnostic code on earlier systems. You may also see intermittent misfire or stalling with no code if the signal drops out briefly.
