Code P0011 2003 Nissan Altima Sedan Description
The 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.
What are the Possible Causes of the DTC P0011 2003 Nissan Altima Sedan?
- 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
- Engine coolant temperature sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Crankshaft Position Sensor (POS)

Im trying to locate the oil control valve for my 2003 nissan altima 2.5...can u give a detailed dicription or picture where it is located on the motor
-
This valve is actualy located on top of timing cover, little back of toward firewall.
It has a 2 wire harness connector.
hope it helps... -
Thank you. Yes the 2003 Altima with VQ (6 Cylinder) engine have the valve on the back as you mention, but the 2003 Altima with QR (4 cylinder 2.5L) had the valve on front.
-
Is it necessary to adjust the timing chain at installing a new IVT valve?
-
I want to solve my code P0011 I changed the valve but it still does not change the oil.?
-
You should change the oil before replacing the valve. Make sure you use 5W-30 oil.
