OBD-II Generic Error Code P2092: How to Fix It

Q: Can I drive my car with a P2092 code?

You can drive short distances with P2092 active, but it is not recommended for extended trips. The fault affects variable valve timing on Bank 2, which can lead to reduced power, poor fuel economy, rough idle, and in some cases increased engine wear. If the check engine light is flashing rather than solid, stop driving immediately as that indicates a more severe condition.

Q: What is the most common cause of P2092?

The most common causes are a faulty camshaft position actuator solenoid on Bank 2, dirty or low engine oil restricting oil flow to the solenoid, or damaged wiring and corroded connectors in the solenoid circuit. An oil change alone resolves a surprising number of P2092 cases.

Q: What is Bank 2 on my engine?

Bank 2 is the side of the engine that does NOT contain cylinder number 1. On most inline-4 engines there is only one bank, so P2092 would apply to the intake or exhaust camshaft. On V6 and V8 engines, Bank 2 is typically the passenger side on most domestic vehicles and the driver's side on many imports, but always confirm with your vehicle's service manual.

Q: How much does it cost to fix P2092?

If an oil change resolves the issue, you are looking at $30–$80 for DIY or $75–$150 at a shop. A replacement camshaft actuator solenoid typically costs $20–$80 for the part, plus 1–2 hours of labor ($80–$200) if done professionally, for a total of $100–$280. If the camshaft phaser actuator itself has failed, costs can rise to $400–$900 or more depending on the vehicle.

Q: Will P2092 cause my car to fail emissions?

Yes. An active P2092 code will cause the check engine light to illuminate, which is an automatic emissions test failure in most U.S. states and many other jurisdictions. The code must be resolved and the readiness monitors must complete their drive cycles before an emissions test will pass.

Abstract

Error code P2092 indicates a low voltage condition in the camshaft position actuator (VVT/VCT solenoid) control circuit on engine Bank 2. This system controls variable valve timing, which helps your engine run efficiently at different speeds. When the ECM detects abnormally low voltage or a short in this circuit, it triggers P2092, which can cause rough idling, poor fuel economy, and reduced engine performance.
