Hello everyone!

Sorry to be reviving an old thread but I'm having a problem right now with my throttle body that I'd like to share and see if someone has insights...

When driving if I do a hard acceleration I get plausability errors.

I tried reving the engine on neutral to see if the codes would come up since it says that is due to plausability between pots but when at neutral there is no errors... only happens when driving.

I was looking at the pwg angle and dwk angles on INPA and noticed that then opening the throttle body the dwk angles would only be registered when the pwg angle was around 15° then the dwk would creep up... anyone has noticed this behavior?

Tomorrow I'll clean the connector and do the Ohmic measurements but any feedback regarding this strange angles are welcome!!

Can anyone share their experience on this?

Thanks!
Gabriel

WoW!

Dear NZ00Z3,

Thank you so much for this wholelot of info!!! I'll definetly try your tutorial... it seems my mdk potentiometer as gone bad for sure...

Giving some feedback...

I removed the throttle body and did the measures on the body connector... values are in specification but I noticed that on the 2-3Pin when I start the movement instead of going down the values(reversed) it actually at first goes up.... I dont know if maybe this is what is causing to throw codes...

At idle: 1780 Ohm
First movement: jumps as high as 1880 Ohm than starts going down normally....

I'll try to clean from the outside as mentioned on the document and see what happens... also will do the measurements now on the DME connector side to check cabling... be right back with more info xD

Currently out of electrical contact cleaner T_T

I'll look out for some during the week and give some feedback if it had some good results!! Thanks for the reply NZ00Z3!!

Also... I saw that I was able to reach some of the contacts without removing the magnet from the throttle body.... will try to do that... and after try some silicone oil.

Yes yes yes!!!!

It seems the repair worked!!!! I just cleaned and measure the pins and the behaviour is completely diferently... working normaly now.

Tomorrow I'll install everything and go for a ride. Thanks a lot NZ00Z3

Hello everyone!

Reinstalled everything together today after the cleaning of the potis and went for a test ride...

Jeez! What a machine!! completely different... The problem was solved and the car is a lot more responsive regarding the gas pedal...

Thanks a lot everyone especially NZ00Z3 for the document
