3000GT Convertible V6-2972cc 3.0L DOHC Turbo 24 Valve (1996)
EGR Temperature Sensor: Description and Operation
PURPOSE/OPERATION
The EGR Temperature Sensor, located on the EGR valve, verifies EGR valve operation. This is done by monitoring the exhaust passage
temperature down stream of the EGR valve. To confirm that the EGR valve is functioning properly, the engine control module expects to see an
increase in temperature at the sensor whenever the EGR valve is operating. In the event of a malfunction the engine control module will set a code
and turn the malfunction indicator light "on". The resistance value of the sensor increases as temperature decreases.
