OBD-II Generic Error Code P0092: How to Fix It

Q: Can I drive with error code P0092?

It is not recommended to drive long distances with this code. The high voltage condition may cause the fuel pressure to be incorrect, leading to poor performance, stalling, or even engine damage.

Q: What causes a P0092 code?

Common causes include a short to power in the fuel pressure regulator circuit, a faulty fuel pressure regulator, damaged wiring, or a defective ECM.

Q: How to clear a P0092 code?

You can clear the code with an OBD2 scanner after repairing the underlying issue. Simply connecting a scanner and erasing the code will not fix the problem; the code will return if the issue remains.

Q: What is the difference between P0091 and P0092?

P0091 indicates a low voltage condition (short to ground or open circuit) in the fuel pressure regulator control circuit, while P0092 indicates a high voltage condition (short to power).

Q: Is the fuel pressure regulator expensive to replace?

The part itself typically costs between $50 and $200, depending on your vehicle. Labor can add $100-$300 if done by a shop. DIY replacement is much cheaper.

Abstract

Error code P0092 indicates that the engine control module (ECM) has detected a high voltage signal from the fuel pressure regulator 1 control circuit. This typically means the circuit is shorted to power or the regulator itself is faulty. If left unchecked, it can cause poor fuel economy, rough idling, or even engine stalling.
