did you replace the sensor in the rear differential at the top??

it serves as an abs and speedometer sensor.

yes i did.but that was before i changed the wire harness. wire harness was changed due to possible broken wires. is it possible that the sensor is now damaged

not really. have a shop check it with a scan tool to verify the signal is reaching the pcm
