Parts for your 2001 Mitsubishi Lancer-Crank angle sensor

2001 Mitsubishi Lancer crank angle sensor

Based on technical sources, the 2001 Mitsubishi Lancer uses a crank angle sensor (often called a crankshaft position/CKP sensor). The Mitsubishi Motors Lancer workshop manual for early-2000s models (Group 13A Engine Electrical) details diagnostics for DTC P0335 and the CKP sensor on 4G9-series engines. AutoZone’s repair guide for the 2002–2006 Lancer 2.0L describes the CKP mounted on the front timing case. Gregory’s-style manuals for CE-series (1996–2002) Lancers also cover a distributor-mounted crank angle sensor on 4G93 engines. That means the sensor is relevant and fitted across 2001 Lancer variants.

The crank angle sensor in a 2001 Mitsubishi Lancer tells the ECU exactly where the crankshaft is and how fast it’s spinning. That lets the ECU time spark and, on fuel-injected models, schedule injection with precision. Without a clean crank signal the engine won’t start, may cut out, or misfire under load. On Lancers with the 4G94 (2.0L), it’s typically a standalone sensor at the front of the engine by the timing belt. On 4G93 distributor-equipped cars, the sensor is integrated inside the distributor and people still call it a crank angle sensor.

Common clues it’s playing up include a no-start when hot, sudden stalling, rough running, the tacho dropping out, or the check engine light with codes like P0335/P0336. Because the sensor itself is sealed, the sensible “maintenance” is really inspection: check the plug and wiring under the bonnet for brittle insulation, oil wicking into the connector, or damage from a previous timing-belt job. On distributor types, watch for oil inside the cap or a tired O-ring that lets oil contaminate the sensor. These are good checks any time the Lancer is in for servicing, especially past 150,000 km.

Replacement is straightforward with the right steps. Always disconnect the battery. For 4G94 cars, remove the right-front wheel and inner guard to reach the timing cover, then swap the sensor and route the loom cleanly, tightening to spec from the factory manual. For distributor-style setups, mark the housing before removal so base timing stays close, after refit, clear codes and let the ECU relearn idle. Use an OEM or quality aftermarket sensor—cheapies can give flaky signals. After replacement, confirm with a scan tool that crank signal is present, and road test to ensure smooth starts and no misfires.

Where is the crank angle sensor on a 2001 Mitsubishi Lancer?

On 4G94 2.0L engines, it’s mounted on the front of the engine behind the timing cover near the crank gear. On 4G93 distributor-equipped cars, it’s built into the distributor assembly. A quick engine code check (under the bonnet plate) helps identify which layout the car has.

What are the signs it’s failing, and can it be cleaned?

Hard starting (especially when hot), random stalling, misfires, no tach movement while cranking, and a check engine light with P0335/P0336 are typical. The sensor itself isn’t really serviceable. Cleaning the connector and fixing wiring issues can help, but if the internal pickup is failing, replacement is the cure.

Do I need to reset anything after replacing the sensor?

Clear any fault codes, then let the ECU relearn by idling for a few minutes and taking a normal drive cycle. There’s no special programming on most 2001 Lancers, but verifying idle quality and start-up behaviour with a scan tool is good practice.
