Where is Bank 1 Sensor 1? 2003 CTS 3.2L (code P0134)
I've read most of the material on the forum about P0134 code. It looks like the heater in the forward O2 sensor is bad or wire is disconnected. My question is:
Where is this 02 sensor and
How easy is it to change via DIY.
I have O2 removal socket. Do I need to treat the threads w/ PB blaster before attempting to remove?
Thanks all in advance
