Greetings from Tennessee, glad to find this...I NEED HELP PLEASE
I have a 2003 4runner that is bugging me out with regards to fixing the "check engine code1201....ASB $29." Still fuzzy about what the $29 means. I had the codes read at the local O'Riellys. This ordeal really began in March-April this year (2018) with the code for replacing a bad O2 sensor "bank 2...Sensor #2. That sensor has been replaced, and as of today 08-01-2018 it now shows as current, not is the history (channel)
I have performed the following with no success:
Taken off and cleaned ALL ASB brake sensor's. The fronts were not real dirty but cleaned anyway. The right front CV boot and Axel was replaced in DEc. 2017 so thats why I checked that one first. The rears had some grease on the probe, cleaned and reinstalled. Check engine light off, at least for apron. 35 miles....BACK ON AGAIN...What do I do now?Frustrated Aloha, DANO
