Where is the Crank sensor located?

The crankshaft position sensor (CPS) on a 1995 Chevrolet Cheyenne is located on the front of the engine, just below the harmonic balancer. It is a small, round sensor with a threaded mounting bolt. The CPS is connected to the engine computer by a wiring harness.

To access the CPS, you will need to remove the serpentine belt and the harmonic balancer. Once the harmonic balancer is removed, you will see the CPS. To remove the CPS, you will need to loosen the mounting bolt and then pull the sensor out of the engine.

When installing a new CPS, make sure that the sensor is properly aligned with the reluctor ring on the crankshaft. The reluctor ring is a series of evenly spaced teeth that create a magnetic field that the CPS can sense. If the CPS is not aligned properly, the engine computer will not be able to determine the position of the crankshaft and the engine will not start.

Here are the steps on how to replace the crankshaft position sensor on a 1995 Chevrolet Cheyenne:

Disconnect the negative battery cable.
Remove the serpentine belt.
Remove the harmonic balancer.
Remove the mounting bolt from the crankshaft position sensor.
Pull the crankshaft position sensor out of the engine.
Clean the mounting surface in the engine.
Apply a thin coat of clean engine oil to the O-ring on the new crankshaft position sensor.
Insert the new crankshaft position sensor into the engine.
Tighten the mounting bolt to 71 inch-pounds.
Reinstall the harmonic balancer.
Reinstall the serpentine belt.
Reconnect the negative battery cable.
Start the engine and check for leaks.

The crankshaft sensor is inside the distributor. Please check out the images below.
