Gear position sensor, inspection/adjustment 850 '94

Steve,

Just a note regarding the flashing arrow and check engine light. I did not get a "check engine" light, just the flashing arrow which after 24hrs (next day) did not return. To eliminate the "check engine" light and erase DLC codes, check the archives...

To check the alignment of the gear position sensor, an alignment tool is needed P/N 9995475....this might explain the other posting explaining three sensors and no fix... the sensor is probably fine, it just needs adjusting. Anyway the following is the procedure:

1) Make sure gear shift is set to position N. Remove the battery, battery shelf and air intake manifold (easy).

2) Remove the transmission cable from rod arm and remove the selector lever. Install alignment tool on control shaft. Check that the shaft is set to position N. The indentation on the tool should align with the marking on the gear position sensor.

3)Adjustment: Remove the dipstick pipe bracket and gear position sensor screws. Rotate the gear position sensor so that the mark on the switch aligns with the indentation on the tool. Tighten sensor screws. Torgue to 25Nm (37 ft.lbs)

4) Reinstall bracket for dipstick pipe. Make sure that the O-ring on the pipe is in place Torque to 25Nm. Install rod arm on control shaft. Transmission cable on rod arm with washer and lock clips. Apply some grease sparingly to the rod arm pin. Install air intake manifold, battery shelf and then the battery.....That's it.

I quess the whole point of this is that the sensor could be working fine, but needs adjustment as previously mentioned.
