Crankshaft Sensor

Murray Wilson · Jan 26th, 2005, 03:39 PM

If the crankshaft position senor is causing the check engine light to come on and yet the engine is running very smothly (no apparent timing issues) is it just the sensor that needs to be replaced? If so where is the best place to get one and what is involved in the installation?

Thank you

I don't have a tech manual but I think it is under the dsitributer. Any ideas would be welcome..

The engine does run well without the sensor. A friend's daughter had her clutch replaced by someone who didn't realize that the sensor is in front of the ring gear on the flywheel. When they pulled the transmission is broke the sensor. Rather than replacing it they opted to leave it out. The truck ran fine, but with the MIL in the on state.

The sensor detects fluctuations in the revolution of the crank shaft.

This is likely a dealer only item. I got one from the dealer for $50. The sensor is a pain to replace. It is on the transmission bell housing at about 1 o'clock when viewed from the engine side of the transmission. A single bolt holds the sensor in place. The head of the bolt is 10mm.

I can't remember if I had the transmission completely supported by it's cross member or if I had the rear lowered for more clearance while installing the sensor.
