OBD-II Generic Error Code P0029: How to Fix It

Q: Can I drive with error code P0029?

You can drive short distances, but it may cause reduced performance, poor fuel economy, and potential engine damage over time. It's best to diagnose and fix the issue promptly.

Q: What does bank 2 mean?

Bank 2 refers to the side of the engine that does not contain cylinder #1. On V6 and V8 engines, it's usually the rear bank. Check your vehicle's service manual to confirm.

Q: Will an oil change fix code P0029?

Sometimes. If the code is caused by sludge clogging the VVT solenoid, fresh oil can restore proper operation. However, if the solenoid or wiring is damaged, replacing the part is necessary.

Q: How much does it cost to fix P0029?

Cost varies: DIY solenoid replacement (part ~$50-150) plus oil change (~$30-70). Professional repair including diagnosis and parts can range from $200 to $800, depending on the root cause.

Q: What is the difference between P0028 and P0029?

P0028 refers to the intake valve control circuit range/performance (bank 2), while P0029 is for the exhaust valve control circuit. Both indicate VVT issues on bank 2 but on different camshafts.

Abstract

Error code P0029 indicates that the engine control module has detected a fault in the exhaust valve control circuit for bank 2. This typically points to a problem with the variable valve timing (VVT) system, such as a faulty solenoid, wiring issue, or low oil pressure. Driving with this code may reduce engine performance and fuel economy.
