96 Grand Am OBD code P0141

[Rich Andrz]

Greetings,

I've gotten the code P0141 with my 96 Grand Am and have been told it is a problem with the wiring. It's my daughter's car and she had some idiot install a new stereo and I've found some wires not reconnected afterward. Does someone know which color wires go where?

Thanks in advance!

A p0141 is an heated oxygen sensor (HO2S) code, A problem with the heater in the second HO2S. That probably has nothing to do with the radio. You probably just have a bad HO2S. Also if the stereo is aftermarket, There will be some wires not connected, most stereos will have a few wires that power things such as; a power antenna, or amplifier, or get power from a dimmer switch, either way there will be wires not connected.

P0141 most likly is the downstream O2 sensor thats bad or the wiring could be damaged.

Thanks to all....

I found that the disconnected wires are indeed the dimmer and another not used with the stereo. The codes were reset and I'll keep my fingers crossed next emission testing.
