M120.980 throttle bodys rewired correctly?

Hy everybody,

I just rewired my working throttle bodys because of briddle insulation.
I didn't check before disassembly, but is it normal that if I turn on the ignition both ETA's go to position WOT.
I'm pretty sure that everything is wired up correctly.
The Injector harness isn't installed, just for information.

Would be great if someone could help me.

best regards from Austria

Rene

Doesn't anyone know the solution for my problem?

I checked up my wiring with Star Diagnosis

All values are correct, but it stores my 16/3 ETA (driver side) as faulty.

Resistance closes throttle R2: 4,32 Ohm
Resistance open throttle R2: 0,54 Ohm
Resistance closed throttle R1: 0,52Ohm


Switches at closed throttle:
S2n
S1ff

best regards
Rene

I did this this morning, rewired the way to long MAF wring . After i finished & started the car it started & ran a little weird for a few seconds ,as it heated up it settled perfectly .
I saw it all on my Star scanner with the values changing .
I scanned the car & erased the fault codes several times , as of now ,Not a single fault code has reappeared .
I also did a Reset on the camshaft values bank 1 & bank 2 .
Have you erased the old codes yet ?.

BTW: Wait for more Answers as the World wakes up & Log's on .

Unfortunatly fault comes again after erasing it.

Here some photos of the values and the fault.
On one photo it's with closed throttle, and one with WOT.
Thanks for help!

best regards
Rene
