EGR Temperature Sensor

-

Remove EGR Temperature Sensor from the EGR valve.

-

Switch multimeter to resistance range of 200,000 ohm.

-

Connect multimeter to terminals of the EGR Temperature Sensor and record resistance.

^

Resistance should be between 80,000 and 160,000 ohms.

-

IF NOT replace sensor.

-

IF YES, continue with test.

-

With multimeter connected to sensor terminals submerge the sensor in boiling water, i.e. 176° - 212°F (80° - 100°C) and observe resistance
reading on meter.

^

Resistance should change from recorded reading in step 7. 

 

-

IF NOT replace sensor.

-

IF YES, the sensor is good, re-install and torque to 20 Nm (15 ft.lb.).

-

Reconnect EGR Temperature Sensor harness connector.
