ACTION REQUIRED

Show/hide table

The shield wire for the primary speed timing sensor (A235-A48 CU SHLD) is terminated at the sensor end of the harness. This wire should not be terminated at the sensor end of the harness it should only be terminated at the ECM end of the harness.

Cut a two inch section of the shield wire (A235-A48 CU SHLD) at the plug connection for the primary speed timing sensor. Pay careful attention not to cut the incorrect wire. The shield wire is the smaller diameter Black wire. Refer to Image1.

Wrap each cut end of the wire with electrical tape.
