Just bought a 2008 impala ...coming up that a wheel sensor needs serviced do I need to get a new one or what?

 

Is the ABS or the Brake light on?

 

Yellow light that looks like this ( ! )

 

And it don't say sensor says service tire monitor system

 

that is the tpm light not abs. if the light flashing or on solid?

 

It's solid

 

then its just a low pressure issue...have the pressures set 2 psi higher than the pressures listed on the placard label in the door pillar. If one of the tire pressures are more than 10psi lower than the others...have that tire leak checked to find a leak or nail.

 

I don't know if this changes anything but I just drove it and it blinks for a second when I first start it then stays solid ...but thanks
