Okay, I have a 00 GT-S. I went the other day to get the emissions done, it failed. lol One the CEL wasn't on( the emission guy thinks the bulb is out in the dash). Now the test itself gave me this.
P0125- Insufficient Coolant Tempature for Closed Loop Fuel Control.
P0141 02 Sensor Heater Circuit Malfunction ( Bank1 Sensor 2).
Okay the guy said these are bulb light in dash out, need new Thermostat, & 02 sensor. The question is which 02 sensor? Front or back??....Vegeta
