I've recently replaced my electric vacuum pump on my JK. I thought this would fix the OBD II codes but no luck. It is still reading the following:

Electric Vacuum Pump Circuit (P258A)
Vacuum Pump Control Circuit/Performance (C1252)

Does anyone have any recommendations?

Thanks,
Austin

Anyone? Traction control light comes on every other time I start the Jeep.

I have replaced the vacuum pump, abs pump, and brake booster sensor so far with no luck. Also checked wheel speed sensors.

Thanks,
Austin
