Question

Where is the speed sensor located? Not the one that is just a plug with a gear on end, the one with the wire?

Answer 1

HI there,

This code can be caused by the speed sensor in the transmission OR the speedometer itself. Signal goes from the speed sensor in the trans to the speedometer, then from the speedometer to the computer. If you have already replaced the sensor in the transmission, then you need to either check the wiring or replace the speedometer to resolve the code.
