2005 Pontiac G6 Electrical Question

Asked by Aug 02, 2015 at 07:13 PM about the 2005 Pontiac G6

Question type: Maintenance & Repair

I had a new catalytic converter installed last
week. When I picked up my car from the
shop, my key fob no longer worked. I
stopped by a dealer, and they tried a new
battery and a new key fob, neither would
work on my car. My key fob is not broken,
it's something with my car. Now I noticed
my cigarette lighter is also not working. Had
a friend check out the fuses and those
looked good. Does anyone know about the
electrical systems that can help point me in
the right direction?

Hey, First: why should a new catalytic converter break all the electrics in your car? But i guess that during the installation some electric wires might have broke or something.

A new key fob would have to be programmed to the car in order for it to work. On my '00 Grand Prix if the "MALL PGM" or "MALL" fuse blows the keyless entry system is disabled. Look for those fuses on your Pontiac. I suspect that someone at the shop used the lighter socket to charge their phone while they were working on it and blew the fuse somehow. HTH. -Jim

My guess is that getting a new catalytic converter has nothing to do with the electronics, just finding it hard to believe that it's just a coincidence that it broke while they were working on my car. And when I questioned them on it, they were kinda @ssholes about it.

The only way I can see the two connected is if the wiring to the downstream oxygen sensor is damaged. When replacing a catalytic converter the downstream oxygen sensor has to be transferred to the new converter. But then again, damaged wiring going to the oxygen sensor would set a trouble code and trigger the check engine light. HTH. -Jim
