2017 Mitsubishi Eclipse Cross crank-angle sensor

Yes, the 2017 Mitsubishi Eclipse Cross uses a crank-angle sensor (commonly called a crankshaft position sensor). This is confirmed by Mitsubishi’s workshop material for Eclipse Cross (GK) models, which documents DTC P0335–P0339 for the crankshaft position sensor circuit in the engine control system, and by MMC/ASA parts catalogues listing a dedicated crankshaft position sensor for the 1.5L turbo engine (4B40). Independent technical databases (e.g., Autodata and OBD-II diagnostics references) also show CKP-related fault codes applicable to this model.

The crank-angle sensor on a 2017 Eclipse Cross is a small but critical bit of kit. Mounted to the engine block and reading a toothed wheel on the crank, it feeds the ECU precise information about crank speed and position so the car can time spark and fuel spot-on. Without it, there’s no reliable ignition timing, injection timing, or misfire monitoring, and the engine will either run poorly or not at all.

For day-to-day servicing, it’s not a scheduled replacement item in Australia or New Zealand. That said, it’s smart to give it a look during major services—especially if the vehicle sees a lot of hot city work or dusty roads. Under the bonnet, check the sensor connector and wiring loom for oil contamination, heat damage, or chafing. Make sure the harness clips are intact and the connector seal is clean and seated. If the engine has had an oil leak in the past, clean the area so grime doesn’t build up around the sensor.

Typical warning signs of a crank-angle sensor issue include hard starting, random stalling, a dead crank/no start, erratic tachometer behaviour, poor fuel economy, and the check engine light with codes like P0335. If those pop up, a proper scan and live-data check is the go. Replacement is straightforward for a trained tech: disconnect the battery, unplug the sensor, remove its retaining bolt, swap the O-ring if fitted, and refit to the specified torque. Some vehicles require an ECU relearn or sync procedure after replacement, a workshop with a scan tool can handle that. Always use a quality OE or OE-equivalent sensor—cheap units can cause intermittent faults that will drive anyone round the bend. Once fitted, clear the codes and road test to confirm clean starts and stable crank signal.

• Pro tip: Don’t ignore intermittent stalls—addressing an early CKP fault can save a tow later.
• If working at home, support the vehicle safely if access is from underneath.

Popular questions

Where is the crank-angle sensor on a 2017 Eclipse Cross?
It’s mounted to the engine block facing a trigger wheel on the crankshaft. Access can vary by engine and undertray setup, many techs reach it from underneath. A workshop manual or parts diagram helps pinpoint the exact spot.

Does the crank-angle sensor need regular servicing?
There’s no fixed replacement interval. During major services (say every 60,000–100,000 km), it’s worth inspecting the connector, wiring, and for any oil or heat damage. Replace only if faulty or physically compromised.

Is it safe to drive with a failing crank-angle sensor?
Not recommended. A marginal sensor can cause sudden stalling or a no-start. If the check engine light shows P0335–P0339 or similar, have it checked promptly to avoid getting stranded.
