guys, my car is giving faults:
-AfterCat oxygen sensor short to B+, Cyl #4-6
Peake Research code: 15 9F...I keep getting this code
-AfterCat oxygen sensor disconnection, Cyl #4-6
Peake Research code: 15 D8...I only had this code once
So I am only going to replace the one post-cat O2 sensor, not both.
Is that OK? Or is there some reason I am unaware of that I should do both?
Also Im not sure which sensor is for cyl #1-3 and cyl #4-6. Does anyone know?
Any other advice is appreciated
Thanks for the help!!!!
