    I keep getting a P0125 code, Coolant temperaturee too low for closed loop fuel system. I have replaced both temperature sensors (3.4l) and code continues to pop up. Any suggestions on what to try next? Is there a 3rd sensor somewhere?

    Thank you.

    3" lift Up front(Donahoe Racing ext. travel coil overs, Camburg UCA's), 1.5-2" lift in the back(aal and some billy 10" stroke short bodies), Bushwhacker Cut-Out fender flairs, 16"x10" Procomp Street locks, and 305/70 Procomp X-Terrains.
    It could be your front 02 sensor.

    Yep. I have discovered that it is indeed upstream O2 sensor. Somewhere i read that the wire is shorted or some other issue, which is why it doesn't just read O2 senosor.

    Does anyone know how I can verify correct wiring for O2 sensor. These have been changed previously and it may be wired incorrectly.

    Thank you.
