Parts for your 1993 Mitsubishi Pajero-Crank angle sensor

1993 Mitsubishi Pajero crank-angle-sensor — purpose, servicing and replacement

Yes, a crank-angle-sensor is relevant and fitted on the 1993 Mitsubishi Pajero. Technical references including the Mitsubishi Pajero/Montero Factory Service Manual (1991–1999, Engine Electrical) and the Mitsubishi 6G72 and 4M40 workshop manuals specify that these vehicles use an engine speed/position sensor (commonly called a crank-angle-sensor). On petrol V6 models (6G72), the crank-angle function is built into the distributor as an optical/Hall sensor providing both TDC and engine speed signals. On the 2.8L 4M40 turbo-diesel, the ECU receives crank position/Top Dead Centre inputs from a timing-case mounted sensor reading a trigger on the crankshaft/pulley.

The sensor’s job is to tell the ECU exactly where the crankshaft is and how fast it’s spinning. That lets the ECU fire the coils and injectors at the right moment for smooth starting, clean idle, decent power and good fuel economy. When the crank-angle-sensor signal is missing or flaky, the Pajero can be hard to start, stall, misfire, or log fault codes. Because the 1993 range spans petrol and diesel, the exact location and replacement method differ slightly, but the servicing mindset is the same: keep the signal clean, the wiring healthy and the mounting solid.

• Typical symptoms: long crank/no start when hot, random stalling at intersections, tachometer dropouts, misfire under load, or ECU fault codes for crank/cam reference.
• Basic servicing: at major services (e.g., 100,000 km), inspect the sensor connector, loom and earths, clean contacts, check for oil contamination inside the distributor (V6), and ensure the harness is clipped away from exhaust heat.
• Petrol V6 (distributor sensor): look for distributor shaft play and oil seal leaks, a leaking O-ring can foul the internal sensor. Replace the O-ring and cap/rotor if worn.
• Diesel 4M40 (timing-case sensor): verify mounting tightness and correct clearance to the trigger wheel, inspect for metal debris on the sensor tip.
• Replacement tips: use quality OEM-equivalent parts, mark distributor position before removal on V6 models, and perform base idle/timing checks after refit. Clear ECU codes and road-test.
• Diagnostic checks: confirm power, earth and signal at the sensor plug, wiggle-test the loom, scope or use a scan tool to verify clean RPM and sync signals during crank and hot soak.

Look after the crank-angle-sensor during routine servicing and the Pajero will reward with easier starts and smoother running, whether it’s the petrol distributor style or the diesel’s timing-case sensor.

Does a 1993 Pajero have a crank-angle-sensor?
Yes. Factory documentation for the 6G72 petrol and 4M40 diesel confirms an engine speed/position input. On the V6 it’s integrated in the distributor, on the 2.8 diesel it’s mounted at the timing case to read the crank trigger.

Where is the crank-angle-sensor on a 1993 Pajero?
Petrol V6: inside the distributor under the rotor/cap. Diesel 4M40: bolted to the timing case, facing the crankshaft trigger/pulley. Access varies, the V6 often needs distributor work, while the diesel usually needs front-of-engine access.

How do you diagnose a bad crank-angle-sensor on a 1993 Pajero?
Check for hot no-start, random stalling and RPM dropouts. Verify power/earth at the sensor, inspect the plug and loom, and view the RPM signal with a scan tool or oscilloscope during cranking. On V6 models, check for oil inside the distributor, on diesels, check sensor clearance and debris on the tip.
