What does engine code P1140 mean?
Code P1140 is a valve timing position sensor located on the right bank side of cylinder head (the left bank sensor would give P1145 code instead). This sensor helps the pcm (engine computer) to control the valve timing to open or close intake valves for optimum performance. If it does, the sensor is bad.
