ABS Light

Hello all, my ABS light and SERVICE ABS SYSTEM light came on, I took it to the shop, the ran a diagnostic and told us the right front speed sensor was faulty, so the replace the sensor and hub, I wasn't having any breaking issues prior to the light coming on and am not having any now, however, the machanic could not clear the light, he Ot a new code sayingC0040 undocumented, which also says it's a right front wheel issue. Any advice before I end up shelling out more cash?

Thanks to all, Eric

Ok, first an ABS light will not cause any braking issues. It just disables the ABS, which in my opinion, is not a bad thing.

Second, mechanics misdiagnose ABS issues all the time. My bet is your wiring going to the hub and sensor itself is the cause of your issue.

Thanks, a couple backyard machanic said I know said the say thing.
