P0011 Scion 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 Scion 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 Scion?
- Low or Dirty Engine Oil
- 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
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0011 Scion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0011 Scion Code
1. What are the common symptoms of OBDII code P0011 in a Scion?
- Common symptoms include rough idle, loss of power, engine misfires, and potentially stalling.
2. What usually causes the OBDII code P0011 in a Scion?
- The most common causes are a faulty camshaft position sensor, a malfunctioning variable valve timing (VVT) solenoid, or issues with the engine's timing chain.
3. How can I diagnose the OBDII code P0011 in my Scion?
- Diagnosing this code typically involves checking the camshaft position sensor, inspecting the VVT solenoid, and ensuring proper timing chain alignment.
4. Can a dirty engine oil cause the OBDII code P0011 in a Scion?
- Yes, dirty engine oil can affect the VVT system's operation and potentially trigger code P0011, so it's essential to maintain regular oil changes.
5. How can I repair the OBDII code P0011 in my Scion?
- Repair methods may include replacing the camshaft position sensor, VVT solenoid, or addressing any issues related to the timing chain or its components.
6. Is it safe to drive my Scion with the OBDII code P0011 present?
- It is not recommended to drive the vehicle with code P0011, as it can lead to more severe engine damage if left unresolved.
7. Can resetting the check engine light temporarily fix the OBDII code P0011 in a Scion?
- Resetting the check engine light may temporarily clear the code, but if the underlying issue is not resolved, the code is likely to reappear.
8. How much does it typically cost to repair the OBDII code P0011 in a Scion?
- The cost can vary depending on the exact cause of the issue, but repairs for code P0011 may range from $200 to $800 or more, including parts and labor.
9. Will driving with the OBDII code P0011 damage the engine in my Scion?
- Continuing to drive with code P0011 can potentially cause damage to the engine, especially if the issue is related to the timing chain or camshaft components.
10. Can a mechanic clear the OBDII code P0011 in my Scion, or does it require a specific repair?
- A mechanic can clear the code, but it is crucial to address the underlying problem to prevent the code from reoccurring and causing further issues.
