What Is a Crankshaft Position Sensor?
A failing crank sensor can stop your engine dead. A Cranbourne West specialist explains.
What it is & what it does
The crankshaft position sensor tells the engine computer exactly where the crankshaft is and how fast it’s turning — essential for timing the spark and fuel. Without a good signal, the engine can’t run.
It’s a small but critical sensor, and a common cause of no-start and stalling faults.
Signs of trouble & how we help
A failing crank sensor can cause hard starting, stalling, cutting out while driving (often when hot), or a no-start — sometimes intermittently. It’s a frequent cause of frustrating, hard-to-find drivability faults.
We read fault codes and live data, and test the sensor, to confirm it before replacing.
