ABS and sensors

Asked by May 12, 2016 at 08:57 PM about the 2004 Pontiac Grand Prix GT2

Question type: Maintenance & Repair

I have  a 2004 Pontiac Grand Prix GT it has about 170,000 miles. Last week
I was driving it and the ABS started kicking in every time I apply my
brake...no ABS light or TC light came on. My check engine has been on for
a while so I took it in and got codes P0030 for 02 Sensor P0327 Knock
Sensor bank 2 and P0336 for crankshaft position sensor......anyone know if
there are two knock sensors? I only found the one on back part of
motor...how are those changed? Do I need to drain anti freeze? Would
knock have anything to do with the ABS coming on...I read somewhere that
it had to do with the ECM and ECM had something to do with ABS.....I think
it was ECM....Thanks for ur help :)

Are you sure it's the ABS kicking in? It could just be warped brake rotors.

hmmmm idk now! I can feel it in pedal.....like locking I guess

pretty sure its ABS..it only does it when applying brake it sounds like ABS kicking on.. no vibration in steering or when going down road also,no ridges in rotors it could use new ones but they are not bad bad. any other thoughts???? will check again just to be sure

Warped rotors or unevenly worn pads can also cause the vibration feel - and all of these will only be felt when you apply the brakes. ABS sensors tell the car to apply braking to a single wheel to regain traction in a single axle.
