Question

How do I fix this if it is the harness or a circuit

Answer 1

Hi there,

If its the harness or the wiring then the break has to be located and repaired. Sometimes the connectors will become loose and when that happens you can push the pins back onto the connector. Most often the issue is with the sensor itself however. Most of the time these require the use of a scan tool to help dial them in.
