2013 Mitsubishi Lancer Camshaft Sensor: What It Does and When to Sort It

Technical sources including the Mitsubishi Motors Lancer CJ/CF Workshop Manual (Engine Electrical) and the Mitsubishi ASA parts catalogue list camshaft position sensors (CMP) for the 2013 Lancer’s petrol engines (4B11/4B12 and 4B11T). That confirms the camshaft sensor is fitted and absolutely relevant to this model.

On a 2013 Mitsubishi Lancer, the camshaft sensor tells the ECU exactly where the cam(s) are in their rotation. That timing info is crucial for sequential fuel injection, ignition timing, and controlling MIVEC variable valve timing. Many Lancers of this year run two CMP sensors—one on the intake cam and one on the exhaust—so the ECU can keep valve timing bang-on under all loads and temperatures. If the signal goes missing or gets noisy, the car can struggle to start, drop power, run rough, or throw the check engine light.

While the camshaft sensor isn’t a scheduled service item, it pays to look after the things that keep it happy. Clean, quality oil helps, because varnish and sludge inside the head can affect sensor reading and cam target wheels. During regular servicing:

• Stick to the oil and filter intervals recommended by Mitsubishi.
• Give the wiring and connector a quick once-over for brittle insulation, oil ingress, or green crust on pins.
• If a fault code like P0340, P0341, P0365, or P0366 pops up, check the harness routing and connector fit before blaming the sensor.

Replacement is straightforward for a competent DIYer, but a scan tool and basic electrics know‑how make it easier. Under the bonnet, the sensors sit at the front/side of the cylinder head(s). Always identify whether the issue is intake or exhaust side on dual‑sensor setups. Use a quality OEM‑equivalent sensor, disconnect the battery, swap the unit, ensure the O‑ring is clean and lightly oiled, and tighten to factory spec. Clear codes and confirm live data shows a stable cam signal and that MIVEC is responding properly on a road test.

Signs it’s time to act include long cranking, misfires, poor fuel economy, a flat spot under acceleration, or the engine defaulting to a limp strategy. Left too long, it can strand the driver or cause unnecessary stress on the catalytic converter—so it’s worth sorting promptly.

FAQs

Does a 2013 Lancer have one or two camshaft sensors?

Most 2013 Lancer petrol variants use two—one on the intake cam and one on the exhaust cam—to keep MIVEC valve timing precise. Some engines in other markets may use a single sensor, but for Aussie and Kiwi CJ/CF models, expect a dual‑sensor setup.

What are the symptoms of a failing camshaft sensor on a 2013 Lancer?

Common signs include hard starting, rough idle, hesitation, reduced power, higher fuel use, and an illuminated check engine light with codes like P0340/P0341 or P0365/P0366. If the signal drops out, the ECU can fall back to a safe mode with dull performance.

Can it be driven with a dodgy cam sensor?

It may still run, but performance and fuel economy will suffer, and it can stall at the worst time. Driving for long with a faulty sensor isn’t recommended—get the fault diagnosed and fixed to avoid further headaches.
