.
Checking the Operation Sound
1. Check that the operation sound of the stepper motor can be
heard from the EGR valve when the ignition switch is turned
ON (without starting the engine).
2. If the operation sound cannot be heard, inspect the drive
circuit of the stepper motor.
NOTE: If the operation sound is not heard, and the circuit is
normal, either the stepper motor or the ECM may have failed.

Checking the Coil Resistance
1. Remove the EGR valve.
2. Measure the resistance between terminal No. 2 and either
terminal No. 1 or terminal No. 3 of the connector at the EGR
valve.
Standard value: 20
− 24 Ω [at 20°C (68°F)]
3. If the resistance is not within the standard, replace the EGR
valve.
4. Measure the resistance between terminal No. 5 and either
terminal No. 6 or terminal No. 4 of the connector at the EGR
valve.
Standard value: 20
− 24 Ω [at 20°C (68°F)]
5. If the resistance is not within the standard, replace the EGR
valve.
.
Operation Check
1. Remove the EGR valve.
2. Connect special tool MB991658 to the EGR valve.
3. Connect the battery positive (+) terminal to terminal No. 2.
CAUTION
Connecting battery voltage to the EGR valve for a long
time could damage the coil.
4. Connect terminals 1 and 3 to the negative (-) terminal of the
battery, in order to test whether the stepper motor vibrates
(with a slight shudder), indicating that the stepper motor is
operating.

5. Connect the battery positive (+) terminal to terminal No. 5.
CAUTION
Connecting battery voltage to the EGR valve for a long
time could damage the coil.
6. Connect terminals 4 and 6 to the negative (-) terminal of the
battery, in order to test whether the stepper motor vibrates
(with a slight shudder), indicating that the stepper motor is
operating.
7. If vibrations can be felt as a result of the test, the stepper
motor is determined to be normal.
