Detailed Description

This Hitachi crankshaft position sensor monitors crankshaft position and sends the signal to the vehicle ECU so ignition timing and engine operation can be managed correctly. Accurate signal output is important for vehicles such as the Chevrolet Camaro, Cadillac XT5, and GMC Acadia, where crankshaft data is part of normal engine control strategy. CPS0151 is made for specific applications rather than universal use, helping maintain the original sensor interface and electrical connection.
