P1078 Infiniti - Exhaust Valve Timing Control Position Sensor Bank 1 Circuit
- 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
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.
Any information is appreciated. Thanks
