What Is a Camshaft Position Sensor?
The cam sensor helps your engine time fuel and spark. A Cranbourne West specialist explains.
What it is & what it does
The camshaft position sensor tells the engine computer the camshaft’s position, so it can time fuel injection and spark precisely (working alongside the crankshaft sensor). On variable-valve-timing engines it’s also key to the VVT system.
It’s a small sensor with a big role.
Signs of trouble & how we help
A failing cam sensor causes hard starting, stalling, hesitation, rough running, or a check-engine light — sometimes intermittently. It can mimic a crank-sensor fault.
We read fault codes and live data and test the sensor to confirm it before replacing.
