Pulse Generator

PULSE GENERATOR

DESCRIPTION
The pulse generator "A" detects the speed of the end clutch retainer. The speed signal is used for damper clutch control, hydraulic pressure control and incorrect gear detection by PCM. The pulse generator B detects the speed of the transfer driven gear. The speed signal is used for shift timing hydraulic pressure control and incorrect gear detection by PCM.





REPLACEMENT
1. Remove the battery terminal (A).





2. Remove the intake air hose and air clean assembly.
3. Disconnect the sensor wire from the control cable mounting bracket.
4. Remove the pulse generator A, B.
1) Disconnect the connector from the sensor.





2) Measure the pulse generator A, B resistance.
Standard value:
Pulse generator A: 245 ± 30 Ohms / 20°C (68°F)
Pulse generator B: 245 ± 30 Ohms / 20°C (68°F)





3) If the result isn't within the standard value, remove the pulse generator A, B.








5. Measure the pulse generator A, B resistance.
Standard value:
Pulse generator A: 245 ± 30 Ohms /20°C (68°F)
Pulse generator B: 245 ± 30 Ohms /20°C (68°F)
6. If the result isn't within the standard value, replace the pulse generator A, B.
7. Apply the ATF oil around the oil seal before installing the oil seal.
8. Install the pulse generator A, B.
TORQUE: 10 - 12 Nm (100 - 120 kgf-cm, 7 - 8 ft. lbs.)
9. Connect the sensor wire to the control cable mounting bracket.
10. Connect the pulse generator connector.
11. Installation is the reverse of removal.
