Can you tell me what the code 4 in the 2011 Chevy Cruze indicates?

Question

Accepted Answer

Fault code P0004 (or simply code 4) on your 2011 Chevy Cruze means that the fuel volume regulator control circuit is registering high, indicating a possible electrical issue within the regulator. This could be caused by various factors, so pinpointing the exact cause may require more information. If your temperature gauge is also acting abnormal or if you're experiencing issues with coolant levels in the overflow tank, the problem may be related. While this code is uncommon, it might not be a major concern - it could be as minor as a faulty temperature sensor. It's advisable to have a mechanic inspect your car at the earliest convenience.
