1997 Mitsubishi Lancer Crank Angle Sensor: What It Does and How to Look After It

Yes — the 1997 Mitsubishi Lancer uses a crank angle sensor. Technical sources confirm it’s integral to the ignition/engine management on CE/CK Lancers of this era. The Mitsubishi Lancer CE/CK Service Manual (Engine Electrical, Group 13A, 1996–2002) describes a crank angle sensor incorporated in the distributor on 4G15 and many 4G93 models. The Mitsubishi Motors ASA electronic parts catalogue for 1997 CK/CE also lists a “crank angle sensor” within the distributor assembly for distributor-equipped engines, with certain distributorless variants using a separate crankshaft position sensor near the timing case. Gregory’s Mitsubishi Lancer 1996–2004 repair manual covers testing and replacement procedures for the sensor in these Australian/NZ models.

On a ’97 Lancer, the crank angle sensor feeds the ECU the exact position and speed of the engine so it can fire the spark and time the fuel right on the money. In distributor models, the sensor sits inside the distributor and reads a slotted wheel to produce signals for reference (TDC) and cylinder identification. If the signal goes walkabout, the ECU loses its place, leading to hard starting, misfires, or a complete no-start.

Common signs it’s on the fritz include:

• Intermittent stalling or no-start when hot, then it comes good when cooled
• Tachometer dropping to zero while cranking or cutting out
• Fault codes like P0335 (crank) or P0340 (cam/distributor) stored in the ECU
• Rough idle and poor fuel economy

Servicing advice for a 1997 Lancer crank angle sensor is pretty straightforward. There’s no scheduled maintenance on the sensor itself, but it loves clean, tight connections and a dry home. Under the bonnet, check the distributor plug for brittle wiring, green corrosion, or oil wicking up the loom. Oil inside the distributor (from a tired shaft seal) can contaminate the sensor — that’s a fix-now issue.

Replacement on distributor-equipped engines is commonly done by swapping the complete distributor, as it’s quicker and avoids fiddly alignment of the internal sensor. If fitting a new unit, mark the distributor’s position before removal, disconnect the battery, and handle the O-ring so it seals first go. After installation, clear fault codes, and have base timing checked with a proper scan tool function — many workshops will pop it into timing-set mode to lock advance so the base mark can be set accurately. Use quality OEM-equivalent parts, cheapies can give flaky signals and driveability dramas.

Popular question: Where is the crank angle sensor on a 1997 Lancer?

On most Australian and New Zealand 1997 CE/CK Lancers with 4G15 or 4G93 distributor ignition, it’s built into the distributor. Some variants with distributorless ignition use a separate crank sensor near the timing cover. Checking the engine code or VIN build data helps confirm which setup is fitted.

Popular question: Can it be cleaned, or does it need replacing?

You can clean and reseat the connector, and repair any dodgy wiring. If the sensor is oil-soaked or the signal is breaking up when hot, replacement is the reliable fix. For distributor models, replacing the whole distributor is often the quickest way to get it sorted.

Popular question: What fault codes point to a bad crank angle sensor?

Common codes are P0335 (crankshaft position sensor circuit) and P0340 (cam/distributor sensor circuit). Pair these with symptoms like intermittent stalling or a no-start and it’s a strong hint the sensor or its wiring needs attention.
