Exhaust Valve Control Range/Performance Problem (Bank 2)
This code indicates an issue with the exhaust valve timing on bank 2.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine has a system that controls the timing of the exhaust valves. If the timing is off, it can cause performance problems, making the engine less efficient and possibly causing rough idling.
What the computer is actually seeing
The engine control module (ECM) monitors the position of the exhaust valve through a variable valve timing actuator. It expects to see the valve positioning data within certain ranges. If the valve's position strays too far from expected values, the ECM triggers this code.
What a healthy reading looks like
The exhaust valve timing should be within 0-60 degrees, referencing the expected angle of the exhaust camshaft at RPMs between 600 and 2000 depending on engine load.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the engine oil level and condition. Replace oil if dirty or low. Decision point: Is oil okay? Yes - Proceed to step 2, No - Change oil and retest.
- 22. Inspect the VVT actuator and its connector for damage or corrosion. Decision point: Is the actuator and connector in good condition? Yes - Proceed to step 3, No - Repair/replace the actuator or connector and retest.
- 33. Using a scan tool, monitor the VVT parameters while driving. Verify if the valve timing is within expected values during acceleration. Decision point: Are values within specification? Yes - Might need further inspection, No - Proceed to step 4.
- 44. Check the timing chain/belt alignment; any signs of wear or stretch? Decision point: Is the timing component in good condition? Yes - Proceed to step 5, No - Replace the timing chain/belt and retest.
- 55. Replace the VVT actuator if no other faults are found. Retest to confirm issue is resolved.
Common causes
- Faulty VVT actuator
- Oil flow issues (dirty or low oil)
- Timing chain/belt issues (stretch or misalignment)
- Electrical connector problems or damaged wiring
- Faulty camshaft or crankshaft position sensors

Frequently asked questions
Is it safe to drive with this code?
Moderate severity suggests you should fix it soon, as it can affect engine performance and emissions.
Will this code come back after repair?
If all underlying issues are fixed, and the repair is done properly, it should not come back.
Why does this code sometimes pair with others?
Codes can appear together due to related components or systems having similar failure modes.
