Hi my Astra H 18XE comes up with PO2125 and PO2120 faults. I have changed the pedal assembly but the faults still show.

Could it be the throttle body or something like a broken wire. The car still drives fine with no obvious faults. I just want to get to the bottom of it. Thanks

Worth looking at the connectors and sometimes works if you disconnect the plugs, turn 360 degrees and refit as if bad connection then it applies a slight bias to the pins when there is a slight resistance against them from twisting it round....works on French cars a treat

Also look for broken wires leading to the connectors, poor earth points and leads, etc
