The camshaft actuator control circuit monitors the variations that occur between the camshaft and crankshaft. These variations are then sent in a corresponding signal to the Powertrain Control Module (PCM). To accomplish this process, the Camshaft Position Sensor (CMP) and Crankshaft Position Sensor (CKP) are used to convert the varying degrees that exist between the camshaft and crankshaft into an electrical signal that is used by the car’s computer to optimize engine timing and performance.
When diagnostic code P2088 OBD2 is stored, it means that the camshaft position actuator controller circuit “A”, located on bank 1, has a low electrical condition.
