Autozone pulled the following codes (excuse the description if it's incorrect... scribbling in the dark):

P0125 - Insufficient coolant temperature for closed loop fuel control

P1133 - manuf code, fuel/air metering (air/fuel sensor circute slow to respond, bank 1?)

P1135 - manuf code, fuel/air metering (Pedal position sensor A circuit intermittent?)

Is anyone familiar with these? I'm thinking emmisions related problems which SHOULD be covered under the emissions warranty. I have 91,400 miles. I'd prefer to have an idea what to expect before I let the stealership try to bulls--- me.

I reset the CEL twice and both times it came back after 4 miles of driving.

 

Any recent mods or changes (besides the CEL) Rick?

 

heres some google help:

"P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control

My coolant temperature has been fine, and the level is fine. However, when I looked in a service manual (by “Haynes”), that same code is listed like this:

P0125 O2 Sensor heater circuit fault.

Wow – could this be my pre-catalytic converter Oxygen Sensor failing? What’s up with the strange description “Insufficient Coolant Temerature for Closed Loop Fuel Control”?

Anyway, if anyone has any experience with these error codes, I’d appreciate the help. Also, if it does turn out to be the O2 Sensor, what are the odds I’ve ruined my catalytic converters? I have two, since the vehicle is California Emissions. "

hope that helps?

 

No mods or changes.
