ABS light

I'm sure this has been covered but I can't do a search from my phone, sorry.
So my GF's 07 4dr JK has an ABS and traction control light on. I scanned the code, said front wheel sensor, so I replaced both. Erased code, lights still come on! Any idea what else could be wrong. Thank you for the help

You mean if the wheels are straight is the steering wheel straight? If so, then yes. And the jeep is bone stock.
What does the abs sensor actually read? Maybe there is something wrong in the bearing or the abs module? Any help would be great

The sensors read the actual wheel speed. Which side was the code for the Lh or the RH side? What was the code that would be a big help?

The code was for the right side wheel sensor, I don't know what the actual code was though, my friend's shop plugged it in, and that's what he said

The code would help because some codes point toward sensor some towards circuitry and some toward module can you get code read again.

For a bad ABS sensor 3 lights will come on: ABS, traction control, and the ESP/BAS light. If your steering isn't centered it'll only be the ABS and traction control. This is from personal experience and on my 07.
Did you drive it after replacing them? Also it might be one of the rear sensors, which are a whole lot easier to replace than the front. Or the tone ring may be gunked up with mud or grease causing the sensor not being able to read the teeth.

Steering wheel centered is the esp/bas light only..... Not as you said. The rest is great info.

Yes all 3 lights are on. I'll have my friend scan it again. I have driven it and the traction control kicks in as soon as you pull away, then it drives fine.
When I pulled the sensors out, it was covered in grease, could it be as simple as that?

Could be, I know I had 2 lights on when my steering wheel was off center. Maybe ESP/BAS and traction control Regardless it was 2.

The sensor should have some "lube" on it, but the tone ring itself should be free and clear of grease and debris. Once you pull the ABS sensor shine a light down the hole to view it. I can have pics in a few days once I change out my hubs.

Sounds silly but double check the plastic connectors of the abs sensors that have the red unlock and lock piece. ( Located behind the shock tube and held up by two christmas tree plugs that you can push into the engine bay from outside) I have plugged them together thinking all was good and sure enough I didn't lock or push the red slider in to ensure a solid locked connection. When this happened to me I had all 3 lights on

Thanks I will double check that plug, so far nothing else has helped. Hopefully it's as simple as that.
