Exhaust A and Intake B camshaft position sensors (Chevrolet Aveo T300)

Exhaust A and Intake B camshaft position sensors (phase sensors) are installed on the rear end of the cylinder head. If there is a fault in the circuit of one of the sensors, the ECU stores a fault code in its memory and uses a bypass engine control program (without changing the valve timing).



You will need: TORX E10 key, flat-blade screwdriver.

NOTE: Replace the camshaft position sensor sealing ring with a new one each time the connection is disassembled.
