Ok i have a ABS light that comes on my 98 cav winter car, i get the code "excessive accelleration left front wheel". now i knew the wiring on the abs sensors always go bad so i checked that first I measured the resistance and its good, so i figured its gotta be the sensor, changed the sensor still does it, i even tried swaping the abs computer with the one out of my 97 2.2 still does it! but its realy weird since the code doesn't come on until i go over EXACTLY 62km/h (about 35mph), and as soon as you shut the car off it goes away until you drive over 62 again, so at that point i checked the pickup ring on the axle, noticed a chipped tooth, so i swap the axle from my 97 into it, take it for a drive no light somes on at 62!! but now the damn thing comes on at about 105km/h same code....
so i have changed the wiring, the sensor, and the computer and the axle, what else could it be!!!?!?
Do 3rd gens store the code in the ECM or is it only stored in the ABS module?
im not too sure, but i have cleared the codes with my snap-on scanner, and the battery has been unpluged on it, still always comes back as soon as you go over that speed
stupid question: Is one tire worn more that the other? Isn't that the main drive tire? if the left side was worn, it would spin slighty faster. Would that do it?
My Sunfire
i actualy checked that too, i swaped my other set of rims on it too and it does the same thing
Piece of debris in the metal ring around the axle?
not that i can see, i cleaned up the ring on the new axle and checked all the teeth on it before i installed it, looked good as far as i could tell
Is the sensor too close to/too far away from the exciter wheel? I've seen that happen before.
I was thinking maybe the code was stored in the ECM. I know 2nd gens store it in the ABS module, so if you clear that, it goes away. But if you've cleared/reset the ECM, then it shouldn't be there.
Third Gens store the code in the PCM (main computer). Your handheld scanner might be able to clear it. Have you checked any of the other wheels? Maybe it thinks that one is going fast, because it thinks another is going slower...
