Hi, I have changed out the VVT Sensors (back and front) also the Crankshaft / Camshaft positioning Sensor's... (Again back and front) Also the sensor down underneath the engine next to the oil filter... But it's still throwing up a code for the Crankshaft / Camshaft positioning Sensor B bank ... What next ??? I'm at a lost for that I should change (all new parts btw)
