Description
1. The PARK/NEUTRAL position switch is an integral part of the gearbox range switch, located on the side of the gearbox, above the shaft of the mechanical gearbox lever (see illustration). The switch is an information sensor for the PCM control unit. One of the functions of the sensor is to prevent the engine from starting if the selector lever is not in the Park position, as well as closing the reverse signal circuit when the selector lever is moved to the Reverse position.
5.1. Mechanical lever position
Adjustment
2. Make sure that the engine can only be started in the Park or Neutral selector position. If this condition is not confirmed, the switch should be adjusted.
3. To do this, it is necessary to loosen the fastening bolts and, turning slightly from side to side, install the sensor in a position in which the engine will start only in the Park or Neutral selector positions. Tighten the mounting bolts.
Replacement
4. Disconnect the negative cable from the battery.
5. Apply the parking brake and move the shift lever to the Neutral position.
6. Locate the PARK/NEUTRAL switch (PNP), which is located on the mechanical gear lever (see illustration 5.1).
7. Disconnect the selector cable from the mechanical gearbox lever.
8. Disconnect the electrical connectors from the switch (PNP).
9. Unscrew the nut and remove the mechanical lever (see illustration).
5.9. Unscrew the mechanical lever nut (A), remove the lever (IN) and unscrew the sensor bolts (WITH)
Note: During this operation, the mechanical lever must not be moved from the Neutral position. If misalignment occurs, place the lever loosely on the shift shaft and set it to neutral before removing the PNP sensor (see illustration 5.1).
10. Unscrew the mounting bolts and disconnect the sensor from the gearbox (see illustration 5.9).
11. When installing a new sensor, you must align the slots (where the shaft is inserted) with protrusions on the body (see illustration). After this, you can place the sensor on the shaft.
5.11. When installing the sensor, it is necessary to align the slots with the protrusions on the body - thus, the sensor will be installed in the neutral position
12. When installing the removed sensor, you simply need to align its planes with the planes on the shaft of the mechanical lever.
13. Install the sensor bolts and tighten them to the required torque.
14. Install the mechanical lever and tighten its nut to the required torque.
15. Connect the selector cable and electrical connectors.
16. The remainder of the assembly is performed in the reverse order of removal.
