P1110 NISSAN 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 may be faulty
- Crankshaft position sensor (POS) may be faulty
- Camshaft position sensor
How do I fix code P1110 NISSANCheck the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P1110 NISSAN code
Labor: 1.0The cost of diagnosing the P1110 NISSAN 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?When there is a gap between angle of target and phase-control angle degree, the valve will stop working and the Engine Control Module (ECM) will trigger the P1110 code.
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine lack/loss of power
- Possible engine rough idle
P1110 NISSAN 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.
