Not necessarily. You said the car makes a vacuum noise so I think there may be a vacuum leak. Check to make sure the vacuum line connected to the brake booster is properly sealed and that there are no cracks or holes in the line. This link can help you troubleshoot if you think your master cylinder is bad.

SOURCE: 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.

My trac light says trac off, and my abs light is on. what does that mean? I have a 1999 grand am Pontiac.


the trac light is the traction control, the abs light means the antilock brake system is not functioning properly. the trac control is no issue. the abs will not cause the brakes to fail but they will lock instead of pulsing.

97 pontiac grand prix problem with the ABS, low


Get in touch with the "Better Buisines Bureau" or your state "Attorney General". Those people have a way of making dealerships like that listen. I can't believe they are telling you that it's not a safety issue, when the pedal goes to the floor. You could try a different dealer, or go to an independent shop.

Abs light and brake light are on. also service


You can test the wheel speed sensors by unhooking the connectors and put ohmeter test leads on the sensor terminals should read around 1100-1600 ohms also the connectors themselves were bad for wires breaking inside the insulation at the connectors from flexing when the wheel is turned back and forth..Note excessive wheel bearing noise from bad bearings have also been known for interferring with clean abs signal also causing abs codes good luck

How do I get the trac off light to go out on 2001 grand am se


I had a similar problem. Assuming you have pushed the trac button and it doesn't turn the light off.. It on the middle console. I went to AutoZone and checked the OBD code for free. Turned out I needed to replace my Throttle Position Sensor and it's fixed. Very simple to replace. Let me know if you need instruction on that.

ABS light is on and no traction light is on. I have a Pontiac Grand Prix 2001 gt. Light stays on always. I don't feel a problem with the brakes.


Check around all wheels to make sure the wires going to the wheel are intact and plugged in tightly. I had the same thing on my 2000 G.P. GT, in my case it was just a broken wire to one of the wheels.
