3. Disconnect the Engine Control Module connector.
4. Check for continuity between terminal 2 of the EGR Temperature Sensor and ground.
Continuity:
Should not exist.
5. Reconnect the Engine Control Module connector.
6. Turn the ignition switch to the ON position.
7. Using a voltmeter, measure the circuit voltage between the harness connector terminal 1 and ground.
Voltage:
4.3 - 4.7 Volts.
If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed,
clear the trouble codes and road test the vehicle to confirm that the repair has corrected the problem and the code doesn't return.
If the same trouble code reoccurs, it is possible that there is an intermittent failure of the component or the ECM. Check for looseness at all
harness junctions and test for an intermittent failure.
