Hey all we just bought our first wrangle and love it, but i have some bugs to work out. I'm getting some error codes and I have a couple ground straps thats are disconnected and im not sure where they go. Please chime in if you can thanks
Sorry I'm not very electrically inclined. When it comes to electrical schematics I'm pretty lost.
Just went through this with my new to me 2011JK. O2 sensor was throwing a code so dealer I bought it from replaced it with a new Bosch unit. Still got code so the sent me to a jeep dealer and they discovered that the Bosch unit was not comparable, replaced it with factory unit and problem solved.Starting with the battery ground clean both ends of the cable and battery post.
On the inside of the fenders where you have pictures of the grounds take them off and clean.
Inside the Jeep on the footwell sides there are those studs also, left and right sides.
More then likely if your getting the o2 codes they are probably bad, replace the o2's with OEM.
A bad ground can throw O2 codes. Before throwing parts at it, focus on the grounds.
There is a well hidden ground that should be suspect.
