Well here are some potential causes of a P0230 code. Hope this helps.

1. Short to ground on control
2. Circuit Fuel pump control circuit open
3. Short to battery voltage on control circuit
4. Harness chafing causing one of above conditions
5. Bad relay Bad PCM

Eh so so. Cruising on the expressway it seems ok but it lacks power for acceleration and it stutters under load. Feels like a miss but is intermittent and only under medium to wot
