Question about 1997 Pontiac Grand Am
The crank sensor is usually located near the crankshaft of the engine, not on the transmission with wires leading to it.
TESTING Fig. 1: Attach suitable jumper wires between the CKP sensor and CKP sensor harness. A DC volt meter can then be attached to the necessary terminals to test the sensor as the engine is being cranked
Typically, when a crankshaft position sensor DTC is set, checking the integrity of the wiring connecting the sensor (using a digital volt meter) to the PCM harness connector is the best way to determine if the sensor is faulty. If the wires all have continuity, and a DTC is set, it is probable that the sensor is faulty. Although a procedure is given here for testing of the crankshaft sensor itself, it is generic, and may not apply to every vehicle. Typically, the crankshaft position sensor harness connector wire leads are labeled. However, it is advisable to use this procedure in conjunction with the wiring diagrams in Section 6 to identify the terminals on the crankshaft sensor before connecting test leads.
