• Check engine light concerns tied to crankshaft position sensor circuits

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This CPS0178 uses a 3-pin male connector and pin terminals, so the harness connection must match exactly. Confirm the engine and model-year listing for your Buick Century, Chevrolet Impala, Chevrolet Monte Carlo, or other listed GM vehicle before replacing the sensor.
