Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I further suppose when opened up it could be checked with a multimeter.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Still trying to diagnose a high idle issue. I�ve got a IAC fault but have replaced the TB with no change. Others have mentioned a faulty potentiometer was the root cause. Just wondering if the pot is housed in the accelerator pedal. Seems like a reasonable location. Thoughts? edit....after more research the pot is in the TB housing.

POST 2Original post

If not a 99, then with drive by wire, the pedal has a pot or pedal is attached to a pot. The TB will have a stepper motor to control the butterfly.

POST 3Original post

Our accelerator pedal doesn't operate smoothly but has spots where it hangs up. This has happened to others and somewhere was a write up disassembling and lubing the potentiometer, and these pictures are from that. There is a screw removed from the pedal and it is lifted out, and I suppose this assembly is under it. I further suppose when opened up it could be checked with a multimeter. A pot normally has 3 wires, that one has 6 so probably 2 pots in it. Two wires to one pot should read full and constant resistance, and the third wire to one of the first two the resistance will vary from min to max as the pedal travels through full range.

oh this is just tremendous! I rethought the whole pot thing and realized the TB internals for the pot is just the chip board connection. The actual pot has to be outside somewhere and has similar action like a pot on an electric guitar. Your post is extremely helpful. I actually mistakenly posted this on the 996 forum. But glad I did since the knowledge on the 996 forum is superior to the others.
