Hi all, new to this forum but not forums in general. Long time member on a Mopar forum. I've had a check engine code forever and know its emissions related but now finally have to go get tested so I need to deal with it. Its a P0135 O2S Heater Performance Bank 1 Sensor 1. Does anyone know if this is driver side or where and does this mean just replace?

Thanks in Advance for help.

 

my 07 h3 gm svc manual does not cover 0135'

what car and engine do u have
