2005 Sportage LX V6 AWD. Recently had entire exhaust system replaced. Check Engine light is illuminated. Pulled the codes and they are:
P0139 - O2 Circuit Slow Response (Bank 1, Sensor 2)
C1237 - Brake Pressure Sensor Voltage Out Of Range, Noise or Checksum Error
C1513 - Brake Light Switch Implausible
ABS light in dash cluster DOES NOT illuminate when car is started or after all other check lights go out. ABS light flickered on/off a few times recently, but now does not appear to function at all. Possibly a burned out bulb?
I was told the ABS module (OEM p/n 58920-2E350) needs to be replaced based on the C1237 code. Is it possible to have the C1237 code WITHOUT the ABS light also being lit unless there is a defective bulb associated with the ABS light?
Any suggestions for verifying the ABS module is defective? Maybe hard braking in a wet, empty parking lot?
Thanks in advance for your input!
