BMW Throttle from E46 320d pinout

Post by JappeEs »

Hello again
I just bought a throttle from a BMW E46, It's a Bosch 0 205 001 040.
Does anybody have the pinout for this? Or anybody who can tell me how to find out what color is what on the cables?
Thanks

This is essentially a glorified potentiometer (hence the designator "R" for resistor). It has an angular range of 0-78° which corresponds to a voltage of 0-5V on Pin 1. Pin 2 is the +5V supply and Pin 4 is ground. The documentation does not state if 0° is 5V or 0° is 0V on Pin 1, you'll have to measure that.
On the left you can see an idle switch, which is open for less than 12% throttle and closed for more than 12% throttle. The switch connects the signal Pin 5 to ground on Pin 8. I don't think it would have much use for OpenInverter or ZombieVerter.

The cable colors are in German as well:
GR - Grau - Grey
WS - Weiß - White
GE - Gelb - Yellow
BR - Braun - Brown
BR/GN - Braun/Grün - Brown/Green

The pink cable seems to be unused in the BMW application.
