Seat Temperature Sensor: Testing and Inspection

NOTE: When checking heated seat elements for continuity, be certain to move the heating element being checked. Moving the element, such as sitting in the seat will eliminate the possibility of an intermittent open in the element which would only be evident if the element was in a certain position. Failure to check the element in various positions could result in an incomplete test.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

1. Disconnect and isolate the battery negative cable. Disconnect the black 4-way cushion heating element wire harness connector.
2. Using an ohmmeter, check the resistance between cavities "B" and "C". The sensor resistance should be between 50 kilohms at 15° C (60° F) and 2 kilohms at 30° C (85° F). If not OK, replace the faulty seat element and sensor assembly.
