P0230 OBD2 Fault Code in 2012 Chevrolet Malibu: Stalling and Starting Issues
My 2012 Chevrolet Malibu is experiencing frequent stalling while driving and sometimes fails to start altogether. I have already replaced the fuel pump, fuel pump relay, and checked the fuel pump fuse and ignition switch. The car occasionally starts after removing and reinstalling the relay, but it often gets stuck and only starts after a delay. Given that the OBD2 code P0230 is showing up, which indicates a fuel injector circuit issue, I'm wondering if there's another underlying cause—such as a faulty wiring connection or a short in the trunk fuse box affecting the fuel pump relay circuit.
Have you made any modifications to the vehicle, such as installing a remote starter or aftermarket alarm? These could potentially interfere with electrical systems and trigger intermittent starting issues.
