Parts for your 2016 Mitsubishi Asx-Crank angle sensor

2016 Mitsubishi ASX crank-angle sensor: what it does and how to look after it

Based on technical references, the 2016 Mitsubishi ASX is fitted with a crank-angle sensor (more commonly called a crankshaft position sensor, CKP). The Mitsubishi Motors service manual for ASX/RVR/Outlander Sport (2016 model year, Engine/Engine Electrical sections) specifies the CKP sensor and its diagnostic routines, while the factory wiring diagrams show the CKP signal as a primary input to the ECU. Mitsubishi’s parts catalogue for GA-series ASX models also lists a dedicated crankshaft position sensor component, confirming it’s standard on both petrol and diesel variants.

On the 2016 ASX, the crank-angle sensor tracks the crankshaft’s exact position and speed. The ECU uses that signal to time spark and fuel injection, sync with the cam sensor for MIVEC/valve timing, monitor misfires, and manage cold starts. Without a clean crank signal, the engine may not start or can run poorly, so this little sensor does a lot of heavy lifting under the bonnet.

• Common symptoms when the sensor or its wiring plays up include a crank/no‑start, hard starting when hot, random stalling, rough idle, flat spots, poor fuel economy, and the check engine light (codes such as P0335–P0339).
• It’s not a scheduled replacement item, but it should be checked during servicing if those symptoms show up or after timing/engine work.

Maintenance is mostly preventative. Keep an eye on the sensor connector and harness routing low on the engine—oil seepage, road grime, or chafed wiring can distort the signal. After major work (timing components, front crank seal, or gearbox removal), it’s smart to confirm the sensor’s mounting is clean, seated square, and the wiring is clipped away from hot or moving parts. If replacement is needed, go for a quality OEM-equivalent unit, fit a fresh O‑ring if applicable, and avoid levering on the sensor nose. A light smear of clean engine oil on the seal helps installation, and the retaining bolt only needs gentle, correct torque. Clear any fault codes and perform an idle relearn if the ECU requests it, many ASX models adapt on their own after a short drive cycle.

A workshop can test the signal with a scan tool or oscilloscope, but a quick driveway check starts with the basics: battery health, secure grounds, clean connector, and no damaged loom near the crank pulley area. Look after those basics and the ASX’s crank-angle sensor will usually go the distance, kilometre after kilometre.

Popular questions

Where is the crank-angle sensor on a 2016 Mitsubishi ASX?
On most 2.0‑litre petrol ASX models it’s mounted low on the engine near the crank pulley/timing cover, reading a reluctor on the crankshaft. Diesel variants also place it low on the block or bellhousing area. Access is from underneath or the front, depending on splash shields and model.

Does the ASX need a relearn after replacing the crank-angle sensor?
Often the ECU will self‑adapt after a few key cycles and a short drive. If the idle is unstable or codes return, a workshop scan tool can run an idle or CKP/CMP sync relearn. Always clear any stored codes after the job.

What does it cost to replace, and how long does it take?
In Australia or New Zealand, parts typically range from affordable aftermarket to pricier OEM. Labour is usually 0.5–1.0 hour if access is straightforward, seized fasteners or extra trim removal can add time. A technician will also inspect the loom and connector to prevent repeat faults.
