Transmission Position Sensor/Switch: Service and Repair
TRANSAXLE RANGE (TR) SWITCHDESCRIPTION
When the selector lever is in the position other than "P" or "N", the electrical circuit for starting the engine is kept in the OFF state by the inhibitor switch. Therefore, the engine does not start even if the ignition switch is turned to the START position. Inhibitor switch is installed on the transaxle case located at the upper end of the manual control shaft and is interlocked with the manual control lever.
By shifting the selector to the "P" or "N" range, the electrical circuit inside the inhibitor switch is connected to form the ignition circuit with which the engine can be started. When the shift is in the R range, the backup lamp lights up as backup lamp circuit is energized.
The inhibitor switch, in addition to the start safety device, also includes a circuit for detection of the selector lever position, for sending signals to the transaxle control module.
ADJUSTMENT
1. Set the select lever to the "N" position.
2. Loosen the control cable (A) to manual control lever flange nut (C) to free the cable and lever (B).
3. Set the manual control lever to the "N" position.
4. Loosen the transaxle range switch body mounting bolts and then turn the transaxle range switch body so the hole in the end of the manual control lever and the hole (cross section A-A in the figure) in the flange of the transaxle range switch body flange are aligned.
5. Insert the special tool to fix the manual control lever and switch body.
6. Tighten the transaxle range switch body mounting bolts to the specified torque.
TORQUE: 10 - 12 Nm (100 - 120 kgf-cm, 7 - 8 ft. lbs.)
NOTE:
^ When setting up the switch body, be careful that the O-ring does not drop from the switch.
^ Tighten the mounting bolts carefully so that the position of the switch body does not move.
7. Check that the select lever is in the "N" position.
8. Adjust the adjusting nut (C) so that there is no slack in the control cable (A) and make sure that the select lever (B) operates smoothly
9. Run the vehicle and confirm that the transaxle is set in each range when the select lever is shifted to each position.
