Question

I got the C102A code on my 2009 Dodge Challenger 6.1L, what is the fix? the ABS and Stability light are ON

Answer 1

C102A Left rear wheel speed sensor

This is also know as a wheel speed comparative performance code, make sure tires are properly inflated and tire sizes are the same, if those are good replace wheel speed sensor,(left rear)

Fantastic info for this performance vehicle thank u

Answer 2

The C102A code indicates a problem with the Left Rear Wheel Speed signal, which originates from the Left Rear Wheel Speed Sensor. Sometimes, mismatched tire sizes or tire pressure can also trigger this code. Begin by checking the tire size and tire pressure. If the problem persists, it may be necessary to replace the Left Rear Wheel Speed Sensor. Here is a link to the code page for more information.
