02 Sensor
I have a 02 GT with 89k on it. Twice in the last two days I have gotten PO141 check engine code for the O2 sensor. Is this the sensor after the manifold or after the CAT. I am assuming I just need to replace it since it is throwing a check engine light. Thanks for the help.

Re: 02 Sensor
P0141 indicates a problem with the heater circuit for the post cat oxygen sensor. Most of the time, this indicates the sensor's heating element is bad, but it could also indicate a wiring issue.

Re: 02 Sensor
I will check the wiring on it. Is there any certain brand you should use for replacing the sensor?

Re: 02 Sensor
I would stick with AC-Delco, Delphi or Standard. Don't even get me started on Bosch (aka JUNK!!!!!).
