Found the solution to my check engine light problem

[miss80five]

Soooooo, got the TSB done by the stealership and my O2 Heater Sensor Monitor completed. HOWEVER, all 4 O2 codes (P0058, P0032, P0052, P0038) are still showing up and I'm assuming its residual? The check engine light is not on at all. After fixing the wiring issues, I'm cautious to clear the OBD or reset the battery for fear that the IM monitors won't cycle through afterwards. Irrational fear? Should I clear the OBD or just reset the battery?

My used TJ came with multiple intermittent O2 sensor codes that the previous owner confirmed were not fixed by new O2 sensors. It turned out to be a bad pre-catalytic converter or two. One finally crapped out and clogged the main catalytic converter. Once all three cats were replaced there were no more O2 sensor codes.

Hi Jerry, I’m original owner of 05 Rubicon SWB 6-speed and have a steady engine light that came on today. A first for me, she has 135k pretty easy miles on her, engine and drivetrain bone stock, methodically maintained, and after ready so many an intelligent post of yours through the years I wanted to ask.. where do you recommend I start sir? I’m no mechanic, and only good at the maintenance basics of taking care of my Rubicon and not beating the crap of her just for kicks.

I'm not Sir Jerry, but I would check for codes.

Assuming you're talking about the amber Check Engine light, that will generate a Diagnostic Trouble Code that is stored in the engine computer. That code(s) can be seen in the odometer display on the instrument cluster by turning the ignition switch on-off-on 3 times within 5 seconds then leaving the switch in the On position. It'll take several seconds for it to display so be patient. It'll have 4 digits following a P like P1234. Do that and let us know what displays. At a minimum it will say DONE if you did it correctly.

Turn you key on off on off on quickly without starting the engine and read the codes on the odometer and report back.
