2003 Chevy Impala.
Engine size = v6.
Dash lights = service traction.
Question = I've been hearing a vibrating sound or grinding sound when i
first push the gas pedal. It used to happen every once in a while and now its
doing it more often. A couple of weeks ago i pushed the gas and the
grinding sound came on, then the service traction system light stayed on.
The light isn't on every time i start my car. It does the sound only when i step
on the gas and the light doesn't come on all the time either. My question is
why or what is making that sound and causing my service traction light to
come on? Oh and when the service traction light is on, my abs light comes
on also.

Answer: You probably have a bad hub bearing and/or wheel
speed sensor. When the service traction light is on, usually
the ABS light is on as well. Either way, there will be a trouble
code stored in the electronic brake control module. If the
noise is like a growling or rumbling sound, or a metallic type
noise, you have one or more hub bearings that are bad. The
wheel speed sensors for each wheel attach and are part of
the hub bearing assembly. You would need to take the car to
a shop that can scan the computer and see what codes are
set to aid in diagnosis. Also, sometimes the wiring harness to
the speed sensors either breaks or gets rubbed through and
that can set the service traction light on too.

Question: My 2005 Chevy Impala service traction light is on and as I'm driving it makes
this noise that sounds almost like I'm driving in the air or motor cycle sounds.

| 12-23-10 Ok thanks. If i wait to long to service this what can happen? |

| If it is a hub bearing noisy, and you wait too long, you risk having the bearing break apart. This can cause the wheel to fall of. This is rare, but I do not know how loud it is without hearing for myself. |
| 5-31-10 is there away to test the speed sensors |
| There are to ways to test them. Using a Digital meter, test the terminals for resistance. Should be about 900-1400 ohms. Also, you can put your meter on AC volts and spin the wheel and look for the reading to change. |
| 1-5-12 THANK YOU. YOU JUST ANSWERED MY QUESTION AS WELL |
| 4-20-12 I have similar problem on my Chevy Impala 2001. This discussion was helpful. Thanks guys. |
