Adjusting the selector lever position sensor and gear shift drive (automatic transmission) (Opel Vectra C)

1. Move the selector lever from the extreme forward position ("P") to the extreme rear position ("D") and make sure that the successively selected positions correspond to the readings on the display indicating the selected gearbox mode. If the readings do not correspond, adjust the selector lever position sensor and gear shift drive.

Transmission AF22/AF33

2. Set the selector lever to position "P".

3. In the engine compartment, in order to provide access to the selector lever position sensor, depending on the model, remove the engine cover, release the device from the latches (see accompanying illustration) preheating system control, unscrew the bolt, loosen the nut and separate the wiring bracket from the sensor.



4. Using the KM6042 device (see accompanying illustration) disconnect the drive cable end from the sensor lever, slide the cable sleeve back and pull it out of the holder. Loosen the sensor lever mounting nut.





5. Make sure that the selector lever position sensor is set to the "P" position (the lever is moved forward to the stop). Using the lever, set the sensor to the "N" position. Remove the lever from the sensor shaft.

6. Use a flat, long enough metal plate (for example, with a caliper ruler), install it so that the side edge of the plate fits against the flat slot of the selector lever position sensor axis (see accompanying illustration), while the plate should be located parallel to the "N" mark.





7. If this condition is not met, it is necessary to loosen the 2 mounting bolts (see illustration 2.6) and turn the sensor to the required value, then tighten the bolts with the required force (see Specifications).

8. Install the sensor lever in place, tighten the fastening nut and move the sensor to the "P" position (lever forward to the stop). Reconnect the cable and reinstall all removed components.

9. If necessary, you can synchronize the position of the selector lever and the sensor; this is done according to the same principle as synchronizing the lever and gear shift mechanism on models with a manual transmission (see Chapter 6, Section 8).

10. In the car, set the selector lever to the "P" position. Remove the front ashtray and, carefully prying it with a small screwdriver, release the drive cable latch, thereby separating it from the selector lever.

11. Set the sensor to the "P" position by pressing its lever forward until it stops, connect the drive cable to the selector lever, snapping the lock. Install the ashtray in place.

12. Perform the operations specified in paragraphs 2-4.

Note: It may also be necessary to remove the expansion tank. According to the layout conditions on these models, the selector lever position sensor lever moves in the vertical plane.

13. Loosen the fastening nut and disconnect the lever (see accompanying illustration).





14. Move the sensor axis to the "N" position by pulling the lever up to the stop and then pressing it down two clicks.

15. Install the test fixture KM-J-44810-A (see accompanying illustration) onto the axis of the selector lever position sensor, while the device should enter the sensor



If this does not happen, it is necessary to loosen 2 bolts and turn the sensor to the required angle. Tighten the mounting bolts with the required force. 16 Installation is carried out in the reverse order of removal. Synchronization is carried out in the same way as for AT AF23/33 (see above).
