One of your wheel speed sensors is not functioning and this is why you are having the abs and trac control light. These are on the back side of your wheel bearing hub assembly and you may have a broken wire or a damaged sensor. Check all four of these visually and with a continuity tester to find the bad one. The check engine light is usually emissions related and I would suggest replacing your O2 sensor.

Abs, service engine light and trac off lights keep coming on


Hello. The ABS [anti-lock brake system], traction control and service engine soon light are all interconnected. The ABS and traction control each depend on sensitive sensors to send a signal to your car's computer that there is a problem. The problem unfortunately is that the sensors themselves are bad. If your brakes still pump themselves when you stop fast, for example, then your ABS system is still working but one of your sensors is sending a signal anyways.
To check everything out you can take your car to many auto parts stores, or most recently AAMCO transmission stores, where they will scan your computer for free. Once the scan is done you will know exactly why the service engine soon light is on.
In the meantime, you do not need to worry about your brakes because all the ABS system does is pump them for you. You can still pump them yourself, like folks did for years before ABS came along. Same is true with the traction control. As long as you do not drive wrecklessly you need not worry.
So to summarize, call around to auto parts stores, or AAMCO to get a free scan. Once you have those results you can decide on how to proceed.

Abs light, trac light, service engine soon light 2001 Pontiac Grand Am


Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

Abs and trac control lights are on


It is one of your wheel bearings. The problem is easily solved by taking the car to a dealer, or having a code reader, and determining which wheel bearing is bad. The wheel bearing is under $150 and should be installed by someone with some muscle, as the bolts are torqued from the factory extremely tight in a tight location. The wheel bearing have all of your sensors for abs built into them and if that sensor goes out your computer tells the abs and traction control to shut down, hence you get the lights on on the dash.

2001 olds ABS and traction control sensor issue


An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
