I am getting the P0221 code more and more often recently. (Throttle/Pedal Position Sensor / Switch "B" Circuit Range / Performance)
The TB has has been refurbished to contact-less, but as it was done before I owned the car, I have no idea who did it and how.
Initially I suspected the PP, so after I looked at it, have found new wires run directly to the ECU( this must be the solution for the ground problem that existed in some cars, I suppose). I checked the voltage on both of the signal wires and found almost no discrepancies between them.
Then I looked at the TB. From Engine Fuel Supply Manual page 82 I know the butterfly should move after turning the ignition to MAR. Mine does like on the video below. Not sure if this looks normal. Could some one advise, please? Any ideas?
