When is the code detected?When there is a gap between angle of target and phase-control angle degree, the valve will stop working and the ECM will trigger the P1145 code.
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine lack/loss of power
- Posssible engine rough idle
P1145 2002 NISSAN PATHFINDER MeaningThis mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.
The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.
The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.
