New Wrangler Owner Needs Help With Codes

[Miked5207]

Hey, new Wrangler owner here. Just picked up a 2010 Unlimited Sport 4 door with roughly 150k on it as my winter vehicle.

I have p0430 - replaced the driver side manifold as it was cracked, still showing the code so I assume it’s the cats.
1st question, should the 2010 have 4 cats or two total? Replacement systems show both setups, mine currently only has 2 (1 on each side) none up by the manifold.

My second question is I had a right wheel speed sensor code and abs lights, found the sensor broken off and replaced it, I still have u0125 and u1003 showing, I only took a quick ride around the block, unsure if it take more to reset

Any help would be greatly appreciated

For your first question regarding the catalytic converters, the 2010 Wrangler typically has two catalytic converters, one on each side after the manifold. It's possible that some replacement systems you found offer additional configurations, but yours should be set up as you described. Since you've replaced the driver side manifold and are still getting the P0430 code, it might be time to check the passenger side converter or examine for any exhaust leaks that could be causing the issue.

Regarding the U0125 and U1003 codes after replacing the right wheel speed sensor, it’s a good idea to drive the vehicle for a little while to allow the car's computer (ECU) to reset and recheck the sensor readings. Sometimes, it takes a bit of driving for all systems to recalibrate, especially if the ABS light is still on. If the lights persist after a solid drive or two, you might want to double-check your installation of the new sensor and ensure there are no issues with the wiring harness or connectors leading to it.

Hope this helps, and good luck with your new Wrangler!
