Why does my 2005 pontiac grand prix say service variable effort steerin, traction control off, and service abs?

You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.

Its the abs sensor, if you encounter an ice patch or snow you won't even be able to stop because the pedal will will push back and make the rip grind noise. If you pull the ABS fuse out, you won't have ABS but you can stop and you won't have the grind noise and back pressure for now. Its safer to not have ABS when the sensor is faulty.

when you pushed caliper piston back dirty fluid traveled through the abs system causing valve to stick ,try bleeding the front brakes and resetting the computer.

the trac shuts off when theres a check engine light or a abs light on, most likely theres a bad abs wheel sensor but you will have to have the abs computer scaned to find out which one it is. hope this helps.

Hello, You need to read system with a scanner to Find out what code is set and what component, Wiring is causing the fault. Would be best to have system read with a GM scanner.
