P0011 Nissan -Pathfinder-changed ivt sensor w/oem part..light came back on..gas mileage bad..why?

Question

This is the third sensor replaced since we bought it 4 mo. ago. last one was from Nissan dealer

Answer 1

The Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code, use 5w-30 oil like mobil 1 or pennzoil platinum

 

Possible causes

- Faulty Intake Valve Timing Control Solenoid Valve

- Intake Valve Timing Control Solenoid Valve harness is open or shorted

- Intake Valve Timing Control Solenoid Valve circuit poor electrical connection

- Faulty Camshaft Position Sensor

- Camshaft Position Sensor harness is open or shorted
