EGR Temperature Sensor: Testing and Inspection
California
1.
Remove sensor from intake manifold, then immerse sensing portion of sensor into a suitable heating container filled with water. Do not allow
temperature sensing portion of sensor to directly touch heated portion of container. Ensure hot water is continually stirred and connector terminal
is held approximately .12 inch above water.
2.
Insert a suitable thermometer into container, then connect an ohmmeter to sensor.
3.
Ohmmeter should indicate the following values:
a. At 122°F, ohmmeter should indicate 6000-8300 ohms.
b. At 212°F, ohmmeter should indicate 1100-1400 ohms.
4.
If resistance values are as specified, sensor is satisfactory. If resistance values are not as specified, replace sensor.
5.
Apply a suitable sealant to threaded portion of sensor, then install and torque to 7.3-8.6 ft. lbs.
