SOURCE: trac light, ABS and service engine soon light won't go off

Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. Antilock systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one or more of the component of the ABS system fails to pass one or both lights will remain lit, the system will shut down and set a code. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

SOURCE: check engine light on,results in code P0446-fuel emission cotrol

Well it could be as simple as a new gas cap, or clean seal on it & tighten again. There are a few other items in the system too, but one common one is the vapor canister gets plugged up with dust & dirt.

2002 Buick Regal Service Engine Soon light PO442 diagnostic code


That is an emissions code. It means you have a small leak in one of the lines. Most likely it the line that goes from the engine to the evap canister in the drivers side rear inner fender well.

you need to find someone with an old type scan tool,or one that has an adapter for the older cars to read the codes. you can also do this by jumping 2 wires on tha obd connector and count the flashes. the first suggestion is the best. get the code and get back to me and we'll go from there. hope this helps Thanks Ray

The error that I'm showing for error code P1133 is 
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank).  I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done.  Hope this helps.  Thanks for an honest rating and for using FixYa.
