2001 Pontiac Grand Prix 3800.ABS and Trac off Lights sometimes. Transmission code was on and speed sensor light, change both front hubs. Question = Ok here goes. My car ran fantastic for a long time. It hit about 60000 miles. I noticed some growling from the car. Happen when i turn corners or inclined driveways sometimes out of nowhere. Shakes steering column. Why does Sometimes it kicks on my abs light and trac off light. Also, and maybe tied with in previous condition list earlier. When vehicle is warm it shifts hard. I took it to a mechanic in my town and he said i had three codes. One transmission code and one code foamy hub assemblies needing replaced. I dont remember what the other cod was. I did however go to auto zone and they tested my car and no codes came up. What do you think could be the issue of these problems. Sorry to add on but I did change both wheel hub assemblies. Answer: The codes are really the key. The trans code are not hub related. If no codes came up at Autozone, then i would suspect the local mechanic cleared the codes,and one or more just have not returned yet, even though the shifting problem. If you can find out what the code numbers were- maybe on mechanics receipt, then i could give some advice.
MY 2001 Chevy Monte Carlo ABS and Service Traction System Warning Light. DTC Code 1216. What does this mean and how much is the repair cost generally. Do you know what the problem is...
1999 Pontiac Grand Am 2.2L 4 cylinder. Warning lights: TRAC off. Question = It has been very cold here...about 4 degrees. I put my park brake on to warm my car up in neutral. When I drove off it seemed like the brake was still hanging up. Then it seemed to bust loose and was fine. That night I was giving a friend a ride home and the left front wheel locked up. I ended up sideways in the street. We jacked it up and checked the wheels. They both turn. We towed it home. Now when I am in anything but park or neutral the trac off light comes on. I can drive a little way, but then the wheel locks up. HELP? I can't get the car in the shop until Wednesday!
Answer: Well, the parking brake shouldn't have any issue on your front wheel locking up. You could have a brake caliper that is sticking and locking up the wheel, or possibly an ABS issue that is keeping the left front line locked with fluid. With the trac off light on, this is most likely related to the ABS problem. When there are ABS codes, traction system is disabled. You'd need to get it scanned to check for trouble codes, which could lead to a possible bad pump motor or modulator valve that is sticking. If you could get the car in the air, have someone spin the wheels while you apply the brakes off and on trying to duplicate the problem. This would show a sticking brake caliper more easily.
