2006 Mitsubishi Lancer Camshaft Sensor – What It Does and When to Replace It

For the 2006 Mitsubishi Lancer, a camshaft position sensor is very much part of the picture. Technical references including the 2006 Lancer Workshop Manual (CS/CT platform) in Engine Electrical (often listed as Group 13A), the Haynes Mitsubishi Lancer 2002–2011 repair manual, and Mitsubishi ASA/CAPS parts catalogues all list a camshaft position sensor (CMP) for the 4G94 2.0L and 4G69 2.4L engines. Diagnostic platforms like Mitchell1/AllData also document CMP circuit testing and common fault codes (P0340/P0341) for this model year. So yes—this Lancer uses a camshaft sensor.

On this Lancer, the camshaft sensor feeds the ECU precise timing of the cam’s position. That info is critical for sequential fuel injection, smooth starting, misfire detection, and, on 4G69 MIVEC engines, accurate valve timing control. When the sensor is healthy, cold starts are crisp, fuel use stays tidy, and it pulls cleanly through the revs.

It’s not a scheduled replacement item, but it’s smart to check it during major services—especially on high‑kilometre cars in Aussie and Kiwi heat. Under the bonnet, oil mist and heat can harden the sensor’s O‑ring and cook nearby wiring, leading to intermittent faults.

Common signs it’s on the fritz include:

• Hard starting or long crank, rough idle, or random stalling
• Sluggish throttle response and average fuel economy
• Check Engine Light with codes like P0340 or P0341

Replacement is straightforward with basic hand tools. Disconnect the battery, locate the sensor on the cylinder head at the timing belt/chain end (near the intake cam on most variants), unplug the connector, remove the retaining bolt, and ease the sensor out. Lightly oil the new O‑ring, seat the sensor squarely, refit the bolt to spec, reconnect, then clear any fault codes. If using a scan tool, perform a quick cam/crank relearn where supported.

Tips that help it live longer:

• Keep the connector clean and properly clipped—don’t leave it dangling near the exhaust manifold
• Fix oil leaks that can soak the sensor and loom
• Use quality OE‑equivalent sensors, cheapies can cause heat‑soak issues and ghost faults

If the Lancer cranks a long time from cold or throws timing‑related codes, a quick inspection of the cam sensor and its wiring beats guesswork. It’s a small part that makes a big difference to how the car runs day‑to‑day.

Popular questions about the 2006 Mitsubishi Lancer camshaft sensor

Where is the camshaft sensor located on a 2006 Lancer?
It’s mounted on the cylinder head at the timing belt/chain end. On the 4G69, look near the intake cam. Access is from the top under the engine cover, some trims may need an air duct or cover moved for room.

Can a bad camshaft sensor stop a 2006 Lancer from starting?
Yes. The ECU can sometimes fall back on crank signals, but a dying cam sensor often causes long cranks, no‑start when hot, or sudden stalls. Fault codes like P0340/P0341 are common clues.

Does a new camshaft sensor need programming?
Generally no. It’s plug‑and‑play on this model. Clear codes after fitting, some scan tools offer a cam/crank relearn which helps the ECU settle quickly.
