2008 Mitsubishi Outlander Camshaft Sensor — What It Does and When To Replace It

Referencing Mitsubishi Motors’ Outlander Workshop Manual (2007–2012, Group 13A Engine Electrical), the factory OBD fault list for this model family (showing DTCs such as P0340/P0341 for camshaft position circuit/performance), and the Mitsubishi ASA electronic parts catalogue, the 2008 Mitsubishi Outlander is fitted with a camshaft position sensor (CMP). The 2.4‑litre 4B12 engine uses a CMP to run MIVEC variable valve timing, and the 3.0‑litre 6B31 V6 uses two CMP sensors — one per bank — to manage timing and sequential injection. So yes, the camshaft sensor is absolutely relevant to this vehicle.

On the Outlander, the camshaft sensor tells the engine control module the exact position of the camshaft in relation to the crank. That’s crucial for quick starts, smooth idle, proper spark and fuel timing, and for the MIVEC system to advance or retard the cams. When it plays up, the driver might notice longer cranking, a lumpy idle, hesitation under load, higher fuel use, and the check engine light. Typical codes are P0340 and P0341.

There’s no fixed service interval for a CMP — it’s a solid‑state part — but it pays to give it a once‑over during scheduled servicing. Under the bonnet, check the sensor connector for green corrosion, brittle insulation, or oil contamination. If there’s oil weeping from the rocker cover, sort that leak first, oil can wick into the plug and confuse the signal.

Replacement is straightforward on the 4B12: disconnect the battery negative, unplug the connector, remove the retaining bolt, and pull the sensor straight out. Lightly oil the new O‑ring, refit, and snug the bolt to spec per the workshop manual. On the 6B31 V6, there are two sensors (bank 1 and bank 2). Access may require removing the intake ducting, take care not to drop bolts near the timing case. After fitting, clear codes, let the engine idle for a few minutes so the ECU can relearn, and take it for a gentle drive around the block.

A quality, OE‑equivalent sensor is worth it — cheap units can cause intermittent faults that are hard to chase. If the Outlander shows the above symptoms or logs CMP‑related DTCs, a proper diagnosis should also include a look at the crank sensor signal and the cam timing (especially if a recent timing or top‑end job was done). That way the owner isn’t throwing parts at a wiring or timing issue.

• Key symptoms: extended cranking, rough idle, flat spots, poor economy, MIL on (P0340/P0341).
• Good practice: inspect wiring and seals, fix oil leaks, use OE‑quality parts, clear and verify with a test drive.

Question: Where is the camshaft sensor on a 2008 Mitsubishi Outlander?

Answer: On the 2.4L 4B12, the CMP sits on the cylinder head near the timing cover, easy to spot under the engine cover. On the 3.0L 6B31 V6 there are two sensors, one on each bank, access is from the top with some intake ducting out of the way. Always identify bank 1 vs bank 2 before ordering or replacing.

Question: Can the Outlander be driven with a faulty camshaft sensor?

Answer: It might start and run in a limited or limp mode, but expect poor performance, rough idle, and higher fuel use. Hard starting is common. Continued driving can be unsafe if the engine hesitates, and it can mask other faults. Best to diagnose and sort it sooner rather than later.

Question: Should the crank sensor be replaced at the same time?

Answer: Not automatically. If diagnostics show only the cam sensor circuit or signal is faulty and wiring checks out, replace just the CMP. If both signals are erratic, or there’s a history of intermittent stalling, inspect the crank sensor and wiring too. Use scan‑data or an oscilloscope trace to make the call.
