P1078 2005 INFINITI G35 Possible Causes

Faulty Exhaust Valve Timing Control Position Sensor Bank 1,Exhaust Valve Timing Control Position Sensor Bank 1 harness is open or shorted,Exhaust Valve Timing Control Position Sensor Bank 1 circuit poor electrical connection,Accumulation of debris to the signal pick-up portion of the camshaft,Crankshaft position sensor

P1078 2005 INFINITI G35 Description

Exhaust valve timing control position sensor detects the concave groove of the exhaust camshaft rear end. This sensor signal is used for sensing a position of the exhaust camshaft. This sensor uses a Hall IC. Based on the position of the exhaust camshaft, ECM controls exhaust valve timing control magnet retarder to optimize the shut/open timing of exhaust valve for the driving condition.
