Good day all, I had an ABS light Park light and traction control lights come on. Went ahead and replaced both front speed sensors, Traction control went off but ABS and park brake light still on. Took it to the local mechanic to check for codes he informed to clean ground cables just under drivers side, They were clean but did it anyway. Lights still on. Going through my pockets noticed I did not put the washers back on between the speed sensor and the hub, could this be causing my problem? If not going to have to take it to a different garage to try and troubleshoot. Thanks. Incidentally had the water pump replaced about a month ago it was shortly after that the lights came on. Thanks.
