HELP: CODE 45

[griffgoody]

I think this code is o2 sensor rich. I changed out o2 sensor. Code still there. Checked fuel pressure at the rail. It was at 38. Changed to 43. Code still there after driving. Is there a way to reset this code (disc. batt cabel for 5 or 10 min). Or is something else wrong. John

disconnect the orange wire near the battery and that will reset the computer, also check the Fuel Pressure again..and make sure with vacuum line off its @ 42/43 w.e your chip is burned for. then with the vacuum line on it should drop a bit to be near 38 psi..

Tks Alot. The pressure is wrong now. They set it with the vacuum line on. Its was right from the beginning at 38 with line on. Will get it corrected.

just take the line off and redo it?
Take the vacuum line off the regulator turn it counter clockwise that should drop FP a bit, or vice versa turn it clockwise to raise fuel pressure then adjust to your desired pressure remember once you put the vacuum line back on it will drop a few psi thats normal. Whats wrong with the car??
