An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other

physical damage to the harness. If no fault is found in the circuit, suspect the following

component(s): - Right hand temperature sensor - catalyst upstream connector. - Right hand

temperature sensor - catalyst upstream. - ECM connector(s). - ECM.

-> No

REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Clear any

DTCs, test the system for normal operation.
