Hey all, I'm trying to trace two issues with my 2014 Leon FR 1.4 Manual. I'm trying to rule out a faulty accelerator pedal. Any expertise gratefully received!
I used OBD11 to read the accelerator position & voltage readings for sensor 1 & 2 over a range of pedal positions and see if they were matching. I've read that differing readings from the two sensors can cause the ECU to get upset and drop power to protect itself.
(Don't worry, I'm aware that the voltage for sensor 2 is supposed to be half that of sensor 1, so I took that into account)
I found that there is a discrepancy of between -0.4% and 1.1% between the throttle position readings of the two sensors (a discrepancy of between -22mV and 72mV)
Can anyone advise if that is enough to cause issues and it's worth changing the pedal, or if that's within expected tolerances?
Cheers!
