TC, ABS warnings
MY '08 SS has ~90,000 Km (~55,000 mi) on it and I am getting the Service ESC and ABS warnings. The only codes my OBD gave me were P0300, 0302 and 0303 engine misfire codes. I have tried to address that by removing and cleaning up the plugs,
I first got the ESC Service and ABS warnings a week or two ago. It came on during one trip to someplace but it didn't come back on the trip back home. It came back on the next time or so that I drove the car and now it comes on every time I drive it.
These are the codes I'm getting related to the ESC Service and ABS warnings:
Right front wheel speed sensor erratic
Right front wheel speed sensor circuit malfunction
C0040 Right front wheel sensor circuit signal amplitude minimum 4
In the old codes section I had a C0899 Battery Voltage Low and a Device 1 voltage low codes. I'm pretty sure those occurred during a cold snap this last winter when the battery got so cold it couldn't turn the car over. I plugged in the battery blanket, got the battery warm and then the car started no problem.
I cleared out all of the codes. I didn't get the ESC Service and ABS warnings when I first started the car but they came on as soon as I put the car in gear and started moving. I haven't checked the codes since. I will check them later.
From the codes I'm getting it would seem that it's related to the right front wheel speed sensor or the wiring harness for that sensor. I replaced the front right wheel bearing hub on that car around 30,000 km or maybe a bit more ago. (I hit a pothole hard and damaged a wheel bearing).. Is the speed sensor in that hub? I don't remember disconnecting and connecting the ABS Sensor harness when I did that job. I might have but I just don't remember doing that.
Today's main task will be to replace the right lower control arm. I will carefully examine the ABS wheel speed sensor wiring harness when I'm in there doing that. Hopefully. it's just a simple wiring or connector issue and not the speed sensor itself.
