How Do I Change the Crank Sensor on a ZX2 Escort?

by Cayden Conor

The crankshaft position sensor on the Ford Escort ZX2 is located behind the exhaust manifold. It sends a signal to the computer that includes the speed of the crankshaft, or engine rpm, and the location of the crankshaft at the No. 1 cylinder. The computer uses this information to adjust engine timing. If the sensor malfunctions, the engine will not start.

Step 1

Disconnect the negative battery cable, using the appropriate wrench. Set it aside, ensuring that it does not touch metal. Raise the vehicle, using the floor jack. Support it with jack stands.

Step 2

Remove the exhaust manifold, using the appropriate sockets to unbolt the manifold at the pipe and at the head. Unplug the crankshaft position sensor, using your fingers.

Step 3

Remove the sensor's retaining bolts, using the appropriate socket, and then remove the sensor from the engine.

Step 4

Lubricate the new O-ring for the sensor with clean engine oil. Install the O-ring on the sensor. Install the sensor and tighten the bolts to 60 inch-pounds of torque. Plug in the wiring harness connector.

Reinstall the exhaust manifold. Lower the vehicle off the jack stands, using the floor jack. Reinstall the negative battery cable.
