Description:

The engine crankshaft positioning sensor determines the crankshaft position. It then sends this information to the onboard computer. The computer uses this and other inputs to calculate injector on time and ignition timing. Symptoms of failure include a check engine light, hard starting and/or poor vehicle drivability. There is no scheduled service for a crankshaft positioning sensor therefore, the part must be replaced when failure occurs. Walker Products began supplying the fuel system needs of the automotive industry in 1946. Today Walker is one of the largest, privately owned manufacturers of fuel system components and engine sensors, and has served the needs of the worldwide automotive aftermarket.
