2018 Mitsubishi Eclipse Cross crank-angle-sensor: purpose, servicing and replacement

The 2018 Mitsubishi Eclipse Cross does use a crank-angle-sensor (commonly called a crankshaft position sensor or CKP). This is confirmed in Mitsubishi Motors workshop service information for the GK-series Eclipse Cross (Engine Electrical section lists the crankshaft position sensor and related DTCs such as P0335–P0339), and in the Mitsubishi ASA parts catalogue for GK1W/GK9W models, which includes a CKP sensor for the 1.5L MIVEC turbo engine.

On this model, the crank-angle-sensor tracks the exact position and speed of the crankshaft so the ECU can time fuel injection and spark with precision. That’s how the Eclipse Cross achieves smooth starts, solid mid-range punch and good economy. If the sensor goes out of spec, the ECU loses its timing reference and can default to limp mode, misfire, or refuse to start altogether.

There’s no routine replacement interval for the crank-angle-sensor on a 2018 Eclipse Cross, it’s a “monitor and replace if faulty” item. As part of regular servicing, a technician will typically scan for stored codes, inspect the sensor connector and loom for oil ingress or chafing, and check live data for crank signal dropouts. Heat, vibration and oil contamination are the usual causes of grief on higher‑kilometre cars.

Common signs it’s time to check the crank-angle-sensor:

• Intermittent no‑start, or stalling when hot
• Misfire under load and poor fuel economy
• Rev counter flicker, or the MIL on with codes like P0335/P0336

Replacement is straightforward for a trained tech. The sensor is mounted on the engine block adjacent to the crank trigger wheel. The process is typically unplug, remove the retaining bolt, swap the sensor, torque to spec, reconnect and clear codes. On some vehicles, a crank variation learn procedure with a scan tool is required so the ECU can calibrate to the new signal. Genuine or high‑quality aftermarket parts are recommended, cheap sensors can produce weak or noisy signals that mimic wiring faults.

Owners can help by keeping an eye out for oil leaks around the front or rear of the block that might wick into connectors, and by addressing any abnormal starting or stalling behaviour promptly. A healthy crank-angle-sensor keeps the 2018 Mitsubishi Eclipse Cross running sweet, with the ECU firing and fuelling exactly when it should.

Popular questions about the 2018‑Mitsubishi‑Eclipse‑Cross crank‑angle‑sensor

What are the symptoms of a failing crank-angle-sensor on a 2018 Eclipse Cross?
Expect intermittent no‑start, hot stalling, rough idle, misfires and poor fuel economy. The check engine light may set codes like P0335 or P0336. Some drivers notice the tacho dropping to zero briefly while the engine is still spinning, which hints the ECU is losing the crank signal.

Does the crank-angle-sensor need regular servicing or a scheduled replacement?
There’s no fixed replacement interval. During routine servicing, a tech should scan for fault codes, inspect the wiring and connector for damage or oil contamination, and review live data. Replace the sensor only if it’s out of spec or causing symptoms.

Can the vehicle be driven with a faulty crank-angle-sensor?
It’s risky. The car may stall without warning or refuse to restart, which isn’t ideal on a motorway or in Aussie/Kiwi summer heat. If faults are logged or symptoms show up, it’s best to sort it promptly to avoid getting stranded and to protect the catalytic converter from misfire damage.
