What is the cost to diagnose the P1111 INFINITI code
Labor: 1.0The cost to diagnose the P1111 INFINITI code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?An improper voltage is sent to the ECM through intake valve timing control solenoid valve.
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine lack/loss of power
- Possible engine rough idle
P1111 INFINITI MeaningIntake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM. 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.
