SENSOR - CRANKSHAFT POSITION
DESCRIPTION
The crankshaft position sensor (1) is mounted in the right rear of the engine block, below the turbocharger, behind a heat shield. This sensor is used to detect engine speed.
OPERATION
The crankshaft position sensor is a magnetic pickup type sensor that generates an A/C signal. The sensor contains a permanent magnet and a coil of wire. The sensor generates an A/C signal each time a notch in the reluctor wheel on the crankshaft passes across the permanent magnet. The ECM calculates engine speed based on the frequency of the A/C signal.
REMOVAL
1. Disconnect negative battery cable.
2. Raise vehicle on hoist.
3. Remove exhaust pipe to turbocharger down pipe retaining bolts and lower exhaust pipe from turbocharger downpipe.
