Parts for your 2023 Mitsubishi Triton-Camshaft sensor

2023 Mitsubishi Triton Camshaft Sensor — Purpose, Service and Replacement

Technical references including the Mitsubishi Triton/L200 MR Series Workshop Manual (Engine Electrical), the 2023 model year diagnostic trouble code list (which includes P0340/P0341 for the camshaft position circuit), and the Mitsubishi ASA electronic parts catalogue confirm that the 2023 Mitsubishi Triton (4N15 2.4‑litre turbo‑diesel with MIVEC) is fitted with a camshaft position sensor. So yes, a camshaft sensor is relevant and used on this model.

On the 2023 Triton, the camshaft sensor (often called the CMP) tells the engine control unit exactly where the intake cam is in its rotation. Working alongside the crankshaft sensor, it lets the ECU line up fuel injection and, on the 4N15 diesel, manage MIVEC variable valve timing. That precise timing helps with clean starts, smooth idle, decent power under load, lower emissions, and stable DPF behaviour. If the CMP signal goes missing or erratic, the ECU may fall back to a basic strategy, which can mean poor starting, rough running, limp mode, or a no‑start with the MIL glowing.

It’s not a scheduled replacement item, but it’s smart to include the sensor and its wiring in routine servicing checks. A quick look under the bonnet for oil wicking into the connector, damaged loom insulation near the cylinder head, or a loose retaining bolt can save a headache later. If there are drivability issues, scan for faults, P0340/P0341 are common CMP codes. A scope trace or live data check comparing cam and crank correlation is the professional way to confirm the fault.

When replacement is needed, use an OE or quality equivalent sensor. Typical best practice is:

• Verify the fault with scans and basic wiring checks first.
• Lightly oil the new O‑ring, seat the sensor squarely, and torque the retaining bolt to spec.
• Clear codes, perform an idle relearn if required, and confirm cam/crank sync in live data.
• Road test and recheck for leaks at the sensor boss.

Common symptoms owners may notice include:

• Hard starting or stalling when warm
• Rough idle, flat spots, or noticeably higher fuel use
• Check Engine light with reduced power or limp mode

Look after the connector and harness routing during other engine work, keep oil leaks in check, and the Triton’s camshaft sensor generally gives long, drama‑free service across plenty of kilometres.

Where is the camshaft sensor on a 2023 Triton?

It’s mounted on the cylinder head near the camshaft gear at the front of the engine. Access is from the top under the engine cover, the sensor plugs into the engine harness with a small two or three‑pin connector. A torch and a 10 mm socket or similar will usually do the trick.

What are the signs the camshaft sensor is failing on a Triton?

Typical giveaways are hard starting, an occasional stall at idle, uneven acceleration, and the Check Engine light. Scanning often shows P0340 or P0341. If symptoms come and go with heat or vibration, inspect the connector and wiring as closely as the sensor itself.

Does the ECU need a relearn after replacing the camshaft sensor?

Most times the ECU adapts automatically after clearing codes. Some scan tools offer a quick cam/crank relearn or idle learn routine, which is good practice. After fitting, clear faults, start the engine, let it idle until warm, and take a short drive while monitoring live data to confirm stable cam/crank correlation.
