Q: What are the details about the Crank Angle Sensor (CAS) and Crankshaft Position (CKP) sensor in Chevrolet Tracker?
A: On 1990 through 1992 Samurai models, the Crank Angle Sensor (CAS) is located in the distributor and serves as an information sensor for the PCM and the "pick-up coil" for the ignition system. It generates a square-wave variable voltage signal as the signal rotor turns, which is sent to the PCM to calculate engine speed and piston position. Failure of the CAS may set a code 42.
