Hi,

Got EPC and visible reduction of rpm, drove for 2 days with intermittent EPC on. After scanning I’ve got these faults: P022100 throttle pedal position sensor a circuit range/ performance, P022100 throttle, pedal position sensor/ switch B range performance, p063800 throttle actuator control bank 1 range performance. Replaced throttle yesterday, turns out the previous one wasn’t an original indicating some earlier problems with it. It looked brand new to be fair. Anyway, after replacement adaptation was done and no more faults appeared. Drove home, EPC came back after 10 minutes. In the morning today turned the key, got EPC alarm again with Check engine, and car stopped after a few seconds. Please advise what else can we check? It’s fabia 1.2 2013 petrol. 105000 miles on the clock, bought it 5 months ago. Thank you

The first two fault codes you mention are related to the accelerator pedal, not the throttle body. I would look for wiring damage near to the pedal connector.

Hi, i had a chance today to get it connected to scanner again, the car started with both lamps on, pressed rhe pedal but it wasn’t making any impact. Scanner showed the 3 codes mentioned in the post and p1565 throttle valve control part j3388 lower stop not reached, and another p00680 map/maf throttle position correlation. After clearing the codes we’ve got p1564 throttle valve control part J338 insufficient voltage during basic with only EPC lamp on. After clearing the codes again, with engine on we moved the cables here and there while watching diagrams but there was nothing out of ordinary at all. We’ve reset the throttle, and after that no more codes and no more lamps on the dashboard. I’m lost now, scared to use this car in case it stops somewhere. Gas pedal now works, wiring seems okay, voltage okay…
