Parts for your 2023 Mitsubishi Triton-Crank angle sensor

2023 Mitsubishi Triton crank angle sensor — what it does and how to look after it

Based on factory and trade references, the 2023 Mitsubishi Triton (MR series, commonly with the 4N15 2.4‑litre turbo‑diesel) is fitted with a crank angle sensor, also known as a crankshaft position (CKP) sensor. The Mitsubishi Motors MR Triton Service Manual (Engine Electrical), the Mitsubishi ASA/EPC parts catalogue for the MR series, and independent repair databases such as Autodata and commonly used workshop diagnostic libraries all document a CKP sensor input for the Triton’s engine management. These sources also list related OBD‑II fault codes (e.g., P0335 range), confirming the sensor’s presence and role on this model year.

On this ute, the crank angle sensor tracks the exact speed and position of the crankshaft. The engine ECU uses that signal to time injection events, manage rail pressure, control boost and EGR, and sync with the cam sensor for precise combustion. If the signal drops out, the ECU can’t reliably fire injectors, which leads to long cranking or a no‑start. In short, it’s a small part with a big job.

Typical tell‑tales of a crook or intermittent CKP signal include:

• Hard starting, stalling, or no start when hot
• Rough idle, misfire‑like shake, limp mode, or an erratic tacho
• Stored DTCs such as P0335–P0339

The crank angle sensor isn’t a routine replacement item in the Triton’s service schedule, but a quick check during regular servicing pays off. Good practice is to scan for pending codes, inspect the loom for chafing near the front cover or bellhousing, confirm connector seals are intact, and make sure the engine and body earths are clean and tight. If the sensor is magnetic, a light build‑up of metal fuzz on the tip can be gently cleaned with electronics cleaner and a lint‑free cloth. Avoid prying tools and don’t alter the mounting face, the air gap is critical and should match workshop manual specs.

When replacement is needed, a quality genuine or OEM‑equivalent sensor is recommended. Usual steps include disconnecting the battery, accessing the sensor on the block (commonly reading a tone wheel on the crank or the flywheel/flexplate), removing the retaining bolt, twisting the sensor free, lubricating the new O‑ring, installing and torquing to spec, then routing the loom exactly as it left the factory. After refitting, clear any codes and perform a CKP/idle relearn with a scan tool if required, then road‑test. Don’t shim the sensor and don’t pressure‑wash the connector. Keeping the loom clipped up properly after other work (clutch, timing cover, accessories) helps prevent future signal issues.

Popular questions

Where is the crank angle sensor on a 2023 Mitsubishi Triton?
On most MR Triton 4N15 engines it’s mounted on the engine block, aimed at a toothed wheel on the crank or at the flywheel/flexplate near the bellhousing. Exact placement can vary slightly by drivetrain, so a quick look under the bonnet and down the block, or a peek from underneath near the gearbox joint, usually spots it.

Can a crank angle sensor be cleaned or does it need replacement?
If the tip has a light dusting of metallic particles, a careful clean can restore a steady signal. If there’s oil intrusion, cracked wiring, or repeated P0335‑type faults after cleaning, replacement is the reliable fix. Always check the harness and connector before condemning the sensor.

Does a new crank angle sensor need programming on a 2023 Triton?
The sensor itself isn’t coded, but the ECU may require a CKP/idle relearn and a fault‑code clear. Many workshops carry out a short drive cycle and verify live data to confirm a stable signal and correct sync with the cam sensor.
