My wife got a code P0134 the other day. It's for the Bank 1, Sensor 1 o2 sensor. I've been looking online but can't seem to find any info on where this is located so that I can try and fix it without having to take it to a shop. Can someone please point me in the right direction? Thank you.

 

Bank 1 Sensor 1 is the rear Air/Fuel Ratio sensor located at the back of the engine. It has the 8P gray connector and goes to the sensor (#9 in parts diagram) in the rear converter.

 

Awesome. Thank you! Is it hard to replace?

 

Yeah I have no clue what I'm looking at. I guess I'll have to go pay a shop to do it.
