The P1012 fault code indicates that the fuel pump delivery pressure is too high. This code is set by the Powertrain Control Module (PCM) when it detects that the fuel pump is delivering fuel at a pressure that exceeds the specified limit.

When the fuel pump delivery pressure is too high, it can cause various issues in the vehicle’s fuel system. It can lead to fuel leaks, damage to fuel lines, and even engine misfires. Additionally, it can put excessive strain on the fuel pump, leading to premature wear and potential failure.

To fix the P1012 fault code, it is important to first inspect the fuel system for any signs of damage or leaks. The fuel pressure regulator should also be checked to ensure it is functioning properly. If any issues are found, they should be addressed and repaired accordingly.

In some cases, the fuel pump itself may need to be replaced if it is unable to maintain the correct pressure.

It is recommended to consult a qualified mechanic or technician to diagnose and resolve the issue to ensure the vehicle’s fuel system operates safely and efficiently.
