Walker Products 235-1269 Engine Camshaft Position Sensor

• Determines the camshaft position

• Sends camshaft position 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

• No scheduled service for a camshaft positioning sensor therefore, the part must be replaced when failure occurs
