P0011 NISSAN Possible Causes

• Low or Dirty Engine Oil
• 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
• Camshaft Position Sensor circuit poor electrical connection
• Faulty Crankshaft Position Sensor (POS)

How do I fix code P0011 NISSAN?

  Check 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 P0011 NISSAN code

  The cost of diagnosing the P0011 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. 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 ECM will trigger the P0011 code.

Possible Symptoms

• Engine Light ON (or Service Engine Soon Warning Light)
• Possible engine lack/loss of power
• Posssible engine rough idle

P0011 NISSAN Description

  This 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 the high-speed range.
The intake valve timing control solenoid valve changes the oil amount and direction of flow through the intake valve timing control unit or stops oil flow. The longer pulse width advances the valve angle. The shorter pulse width retards the 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.
