Traction Control Problem and C1221/C1222 Codes
Im getting codes 1221, 1222 which are front wheel speed sensor left/right input 0 codes.
First places to look?
This is a result of basically not operating, i got the traction active to come on once on a hard 1-2 shift but never again.

What do the wheel sensors use as a trigger?? There are some drilled/slotted Rotors on there and I see nothing resembling an abs ring on the rotor. I cleaned the inside of the studs and they seem to line up with the sensor.
The connection at the spring clips were loose. I bent them and they're snug now.
I'll check for voltage after work.

Fixed!!!! Not sure what it was. Opened and cleaned both connectors on both cables. Tightened right front clip. Cleaned both chassis grounds behind lights. Active handling came on first turn I rolled into it. Next light I rolled into 2nd gear and when it spun up tc light came on. No codes now on dash. Thanks so much for all the help. This forum is kicking butt!!!
