Parts for your 1992 Mitsubishi Pajero-Crank angle sensor

1992 Mitsubishi Pajero crank angle sensor

Based on technical references – including the Mitsubishi Pajero/Montero V20 Series Workshop Manual (1991–1998, Engine Electrical – Ignition/MPI), the Mitsubishi ASA/CAPS electronic parts catalogue for V20 models, and general repair guides such as Gregory’s/Haynes for 1991–1997 Pajero – the 1992 Mitsubishi Pajero petrol V6 (6G72) uses a crank angle signal provided by a sensor inside the distributor. It’s commonly called a crank angle sensor even though it’s physically in the distributor and reads the trigger disc to report engine speed and angle. For 1992 diesel models (notably the 2.5L 4D56 with mechanical injection), there isn’t a dedicated crankshaft position/crank angle sensor, timing is governed mechanically by the pump and flywheel marks, with no separate CKP listed in the factory parts catalogue for that year. So, this page applies to the petrol V6-equipped 1992 Pajero, it’s generally not relevant to the same-year mechanical-diesel variants.

For owners of the 1992 Pajero V6, the crank angle sensor is the quiet hero of smooth starts and crisp throttle response. Housed in the distributor, it tracks the trigger wheel and feeds the ECU and ignition amplifier the all‑important engine speed and position signals. That data is what the vehicle uses to fire the spark at the right moment and manage fuel delivery. When it’s healthy, the Paj fires up quickly, idles evenly, and pulls strongly. When it’s not, expect intermittent stalling, misfires, a dead‑as‑a‑dodo no‑start, or a tachometer that drops out just before the engine cuts.

There’s no fixed replacement interval in the factory literature, but it’s smart to check the distributor and sensor at major services, especially if the vehicle sees Aussie or Kiwi heat and dust. Common issues are oil creeping past the distributor shaft seal and contaminating the optical/Hall pickup, brittle wiring near the plug, or internal wear in the distributor that lets the trigger wheel wobble.

• Keep the distributor dry and clean, fix any oil leak at the shaft seal early.
• Inspect the sensor connector and loom for heat damage and green crusties, clean with contact cleaner.
• If misfires or no‑start appear, scope or meter test the sensor output and check for consistent RPM signal during cranking.

Replacement is straightforward for a competent DIYer, but many workshops simply fit a complete replacement distributor because it solves sensor plus mechanical wear in one hit. If replacing the sensor or distributor:

1. Disconnect the battery, set the engine to TDC on No.1, and mark the distributor position and rotor orientation.
2. Swap the unit and fit a fresh O‑ring, seat it carefully so the drive engages.
3. Tighten the hold‑down bolt snugly, reconnect, and set base timing with a timing light according to the under‑bonnet sticker (typically around the 5–7° BTDC mark at warm idle with timing mode enabled).

Done right, the Pajero V6 rewards with reliable starts, better economy, and that familiar, torquey pull up hills and across paddocks.

FAQs

Where is the crank angle sensor on a 1992 Pajero?
On the petrol 6G72 V6 it’s built into the distributor, under the rotor, reading the trigger disc. On the same‑year mechanical‑diesel 4D56, there’s no separate crank angle sensor.

How can someone test a suspect crank angle sensor?
Check for a steady RPM signal during cranking with a scan tool or scope, verify clean power/earth at the sensor plug, and inspect for oil contamination under the cap. If the signal drops out as it warms up, the sensor or distributor is likely failing.

Can the sensor be replaced without changing the whole distributor?
Sometimes, yes, depending on the exact distributor fitted and parts availability. Many techs prefer replacing the complete distributor to address both the sensor and any shaft/bearing wear in one go.
