So here's the skinny.
I've swapped a '90 EJ22 automatic engine into the rump of an '87 VW Vanagon. I know having just read that sentence you're probably thinking "post this in the Vanaru section"... Well, this thing runs great, and I'm just trying to get some more info on how the switches functioned when they were in their original enviornment so I know what I need to replicate to stop the last of my check engine codes.
I understand that 51 is the "inhibitor switch". I've done some research and found that the switch connects between the ECU and ground. What is the expected state of this switch? Meaning, when the ECU looks at this switch does it want to see a clear path to ground at startup and then no ground before the vehicle begins to move, or does it want to see nothing, then a ground just before moving?
I have the same question about the Parking switch ( code 52). This switch also attaches to both the ECU and ground.
For what it's worth I've gutted the reed switch and magnet from the Subaru instrument cluster and created my own VSS so the engine does in fact know when the vehicle is in motion. Hence no code 33.
I've searched over 13 pages of info without finding the specific info I am looking for. Any help would be greatly appreciated.
thanks in advance,
Jake
