Good day everyone. I need some help with my Fiesta ST. Here's the summary of my troubles:
2017 Ford Fiesta ST, Euro spec, South Africa
Mods: Downpipe, exhaust, stage 1 software
P083F
"clutch pedal switch A/B correlation"
P2121
"Throttle/pedal position sensor/switch 'D' circuit range/performance"
Randomly and intermittently, the car will go into limp mode for a couple of seconds. It happens only when under light throttle or when pulling off in first gear. Sometimes, the engine actually cuts out and the screen displays the "press clutch to turn on" message as if I stalled it (I'd be moving at a constant speed, in gear, and it would do this then go back to normal. I don't suspect it actually shut off)
It's only been happening after I hit a large pothole and dented my wheel.
Sometimes it will also stall/cut out properly when not in gear, or it'll drop revs then go back to normal right after.
It seems as if the car is perfectly fine. Performance is normal, all electronics are normal. I even replaced the battery, which didn't help at all.
Possibly unrelated, I am hearing a slightly clunking noise by the driver side footwell/front right wheel when stationary as if driving slowly over small and loose stone bricks. It also seems to get louder when I'm pulling off. I'm suspecting that my driver side mount is shot.
No check engine light, only when it does the weird stall/no power with throttle for a couple of seconds, right after it turns off. No DTC's. However, the codes listed above were from continuous memory of the PCM. But I cleared them, and the no power moments stopped for a bit, but now came back.
I have a couple of theories: the throttle pedal is toast; the wiring loom for the clutch switch and throttle pedal probably is slipping out every so often (roads are bumpy here); maybe a ground connection is shorting somewhere ; a wire is loose on the ecu.
Any help will be greatly appreciated!
