Parts for your 2017 Mitsubishi Eclipse cross-Camshaft sensor

2017 Mitsubishi Eclipse Cross camshaft sensor — what it does and how to look after it

Technical sources confirm the 2017-build Mitsubishi Eclipse Cross (GK series) is fitted with a camshaft sensor. The Mitsubishi Motors Workshop Manual for GK models covers the Camshaft Position Sensor (CMP) in the Engine Electrical section and lists related OBD-II DTCs (such as P0340/P0341). Mitsubishi’s ASA electronic parts catalogue for GK1W/GK9W variants also lists a camshaft position sensor for both the 1.5L MIVEC turbo petrol (4B40) and the 2.2L diesel. That makes the camshaft sensor very much relevant to this vehicle.

On the Eclipse Cross, the camshaft sensor keeps the engine timing sharp by telling the ECU exactly where the cam is in its rotation. With MIVEC variable valve timing, that signal helps the ECU fine‑tune valve timing for smooth starts, tidy idle, better fuel economy and decent pull when overtaking. It also works with the crank sensor so the ECU knows which cylinder is on its compression stroke for precise fuel injection and spark.

It’s not a regular “service item” like oil or filters, but it’s smart to keep an eye on it during routine servicing. A quick scan for stored fault codes, a visual check of the sensor connector, and making sure the loom isn’t chafed or oil-soaked will head off dramas. If the engine throws a check engine light with codes like P0340/P0341, or there’s rough starting, misfiring, stalling at idle, limp behaviour, or higher than usual fuel use, the cam sensor or its wiring could be the culprit.

Replacement is straightforward for a trained tech: disconnect the battery, access the sensor at the cylinder head, unplug, remove the retaining fastener, swap the sensor, then clear codes and verify live data and timing synchronisation. Because the sensor relies on a clean signal, using quality parts and ensuring the mounting face is clean matters. If oil leaks are present near the rocker cover, fix those first so the new sensor and connector stay dry.

Most owners won’t need a camshaft sensor before high kilometres, but vehicles that see lots of heat cycling, stop‑start city driving, or have had previous oil leaks may see earlier issues. As part of a normal service on a 2017 Eclipse Cross, asking the workshop to scan the ECU, check harness condition, and confirm there are no timing correlation codes is an easy, low-cost bit of insurance.

• Common signs it’s on the way out: hard starting, erratic idle, sudden stalling, sluggish response, higher fuel use, and a check engine light.
• Best practice: address wiring/connectors first, then replace the sensor if tests show weak or no signal.

FAQs

Does the 2017 Mitsubishi Eclipse Cross actually have a camshaft sensor?
Yes. The factory Workshop Manual for the GK-series Eclipse Cross documents the Camshaft Position Sensor and related diagnostics, and the Mitsubishi ASA parts catalogue lists the sensor for both petrol and diesel variants. It’s essential for MIVEC variable valve timing and accurate injection/spark control.

What symptoms point to a failing camshaft sensor on a 2017 Eclipse Cross?
Owners may notice hard starting, rough idle, stalling at lights, a lack of grunt, poor fuel economy, and a check engine light. Scan tools commonly show codes like P0340 or P0341. Always check wiring and connectors before condemning the sensor.

Is it safe to keep driving with a dodgy camshaft sensor?
It may run, but performance and reliability suffer, and it could stall at awkward moments. Continued driving can trigger limp behaviour and mask other faults. It’s best to diagnose promptly and sort the wiring or replace the sensor to keep the Eclipse Cross running sweet.
