Parts for your 1999 Mitsubishi Lancer-Crank angle sensor

1999 Mitsubishi Lancer crank angle sensor — what it does and how to look after it

Yes, the 1999 Mitsubishi Lancer uses a crank angle sensor. Technical references including the Mitsubishi Lancer CE Series Service Manual (MMC, 1996–2003, Engine Electrical), Autodata technical data for Lancer CE 1.5/1.8 (1996–2000), and the Haynes Mitsubishi Lancer 1996–2006 manual all confirm that CE-era 1.5L 4G15 and 1.8L 4G93 petrol models sold in Australia and New Zealand have a crank angle sensor. On most of these cars it’s built into the distributor (often described as an optical/Hall sensor inside the distributor body). Some later or variant setups may use a separate crankshaft position sensor near the crank pulley, but the CE 1999 models commonly seen locally run the in-distributor type.

In simple terms, this little sensor tells the ECU exactly where the engine is in its rotation so it can fire the spark and inject fuel at the right moment. If it goes out of spec, the Lancer can be hard to start, cut out when hot, misfire, or log fault codes (often P0335/P0340 style codes in scan data). Because the ECU relies on a clean position signal, even a small hiccup can feel like a big drama at the wheel.

There’s no set replacement interval — it’s a fit-and-forget item until it fails or wiring/connectors play up. On CE models with the sensor inside the distributor, the usual fix is to replace the complete distributor assembly because the sensor isn’t always a practical separate service item. When replacing, a workshop will typically:

• Disconnect the battery and mark the distributor’s position relative to the head to preserve base timing.
• Swap the unit, fit a fresh O-ring, and reconnect the loom with dielectric-safe practice.
• Verify base ignition timing and idle with a scan tool or timing light as specified in the service manual.

Good preventative habits help: keep the distributor area dry (avoid pressure-washing), check the engine earths, and inspect the loom where it passes the timing cover. If the engine stalls when hot, the tacho drops to zero abruptly, or there’s a no-start with fuel and spark seemingly missing, put the crank angle sensor high on the checklist.

Technical sources: Mitsubishi Motors Lancer CE Service Manual (Engine Electrical: Ignition/EFI), Autodata Technical Data & Wiring for Lancer CE 1.5/1.8, and Haynes Mitsubishi Lancer 1996–2006 repair manual, all of which document the crank angle/crankshaft position sensing arrangement on these models.

Popular questions about the 1999 Mitsubishi Lancer crank angle sensor

Where is the crank angle sensor on a 1999 Lancer?
On most AU/NZ CE 1.5 and 1.8 models it’s inside the distributor on the end of the camshaft. A few variants use a separate sensor at the crank pulley behind the lower timing cover. If you see a conventional distributor with a multi-pin plug, yours is almost certainly the in-distributor type.

What are the symptoms of a failing sensor?
Intermittent no-start, sudden stall then restart after cooling, rough idle, misfire under load, and a dead tacho when it cuts out. Scan tools may show codes like P0335 or P0340. Heat and oil ingress into the distributor can make the problem worse.

Can it be replaced without changing the whole distributor?
Sometimes, but on most CE units the sensor is part of the distributor assembly and replacement of the full unit is the reliable route. Expect roughly an hour of labour plus time to check timing. Using quality parts and reseating the O-ring helps avoid future oil leaks into the housing.
