Exhaust System Temperature Indicator: Testing and Inspection
FAULT DIAGNOSIS HINTS
When current (+15 circuit) is applied to pin 4 of the relay, the warning lamp is grounded and lights up for about 3 seconds. If it remains alight, this
indicates a break in the temperature sensor circuit. Normally, the warning lamp will go out and stay out until the temperature exceeds the preset
limit.
1. Also check that fuse 17 is intact and that current is supplied to the temperature sensor and the relay.
2. Also check the connectors, wiring harness and ground connections.
