2014 Mitsubishi Lancer Camshaft Sensor — What It Does and How to Look After It

Based on technical sources, the 2014 Mitsubishi Lancer is fitted with a camshaft position sensor (CMP). Mitsubishi’s Lancer CJ/CF factory service manual (Engine Electrical section: Camshaft Position Sensor, DTC P0340/P0341) details the sensor’s function and diagnostics for 2014 models. The Mitsubishi electronic parts catalogue (ASA/EPC) also lists a CMP for 4B11/4B12 engines used in these cars. Independent reference guides (e.g., Haynes/Autodata) likewise document CMP testing and fault codes on 2014 Lancers. So the camshaft sensor is relevant and used on this vehicle.

On a 2014 Lancer, the camshaft sensor tells the engine control unit exactly where the intake cam is, so it can sync fuel injection and ignition and manage MIVEC variable valve timing. Without a clean, accurate signal, the ECU can’t line everything up properly, which can mean hard starts, rough running, and worse fuel use. It’s a small Hall‑effect sensor, mounted on the cylinder head at the timing chain end, reading a trigger on the cam.

This isn’t a regular service item, but it does benefit from a quick look during scheduled servicing. The sensor lives in a hot, oily spot, so the usual culprits are heat-soaked connectors, brittle wiring, or oil intrusion past the O‑ring. A quick visual for chafed loom, green corrosion on pins, and weeping around the sensor body goes a long way.

If the Check Engine Light pops on with codes like P0340 or P0341, or the car cranks longer than normal, it’s worth testing the CMP circuit. A proper scan tool readout and basic wiring checks will tell whether the sensor or its feed is the issue. If replacement’s needed, it’s straightforward: disconnect the battery, unplug the connector, remove the retaining bolt, ease the sensor out, lightly oil the new O‑ring, refit, and tighten to the factory torque spec from the Mitsubishi manual. Clear codes and take a short drive so the ECU can relearn trims.

Owners should stick with quality OE or reputable-brand sensors, cheap imitations can cause intermittent faults that mimic timing problems. In Aussie and Kiwi conditions—stop–start traffic, heat, and dust—keeping connectors clean and secured is half the battle. If a CMP fault keeps returning, have the timing chain phasing and the cam trigger wheel inspected as well.

• Typical symptoms of a failing CMP: long crank/no start, rough idle, hesitation, poor economy, limp mode, and Check Engine Light with P0340/P0341.

Popular questions about 2014 Mitsubishi Lancer camshaft sensors

Where is the camshaft sensor on a 2014 Lancer?
It’s mounted on the cylinder head at the timing chain end, reading the intake cam. In the Lancer’s transverse layout, that’s typically at the left-hand end of the engine when facing the car. The connector and a single retaining bolt are visible once the engine cover is off.

Can a faulty camshaft sensor be cleaned, or does it need replacing?
The CMP is a sealed Hall-effect sensor. If it’s just oily or dusty, a gentle wipe of the tip and a contact-clean of the plug can help. If it’s electrically out of spec or logging P0340/P0341 after checks, replacement is the fix.

Does the 2014 Lancer have one or two camshaft sensors?
Most 2014 Lancer non‑turbo variants use a single sensor on the intake cam. Performance variants with dual‑cam phasing may use sensors for each cam. Always confirm by VIN against the parts catalogue or service manual.
