INPA code "Throttle valve pot. 2" -- which TPS is that?

[heinzboehmer]

Realized I never updated this with my findings.

Swapped all three things on my car and while doing so, I decided to disconnect each TPS one at a time and check codes to finally settle the debate.

TPS by the oil filter housing disconnected:



TPS on the throttle actuator disconnected:



Pedal disconnected:



In summary, TPS 1 is by the oil filter housing, TPS 2 is on the throttle actuator and the pedal throws its own codes.

Edit: Oh! Caveat to all of this is that I'm running CSL engine management. I think the mapping is the same as stock, but did not confirm that.

FCP will actually let you "trade up" from OE to Genuine BMW. Buy the Genuine BMW from them and then send the OE part back as a warranty return and they'll refund it, so, you just pay the difference, and you retain lifetime warranty on the BMW part. ...

Only if it's within 90 days of purchase. Learned that recently.
