P0011 Lexus Code - Camshaft Position 'A' Timing Over-Advanced or System Performance Bank 1
Quick Answer
The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. Common causes include Low or Dirty Engine Oil, Valve timing, Faulty Camshaft Timing Oil Control Valve Assembly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0011 Lexus Description
The camshaft timing oil control valve assembly is a solenoid valve and switches the engine oil line. The valve moves when the Engine Control Module (ECM) applies 12 V to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.
The ECM optimizes the intake valve timing using the Variable Valve Timing (VVT) system to control the intake camshaft. The VVT system includes the ECM, the camshaft timing oil control valve assembly and the VVT controller (camshaft timing gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft.
If the difference between the target and actual intake valve timing is large, and changes in the actual intake valve timing are small, the ECM interprets this as a VVT controller stuck malfunction and stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0011 Lexus?

- Valve timing
- Faulty Camshaft Timing Oil Control Valve Assembly
- Camshaft Timing Oil Control Valve Assembly circuit is open or shorted
- Camshaft Timing Oil Control Valve Assembly circuit is open or shorted
