Hi,

Ford focus c max 1.8 petrol, customer came in with poor idle and would not rev out.Also pats light flashing quickly intermittently, causing no crank.Speed limiter warning message on dash.
Battery now changed as it had a dead cell.

Checked Pcm codes, p2110 throttle actuator - forced limit.

p0605 pcm rom error, p0607 control module performance,p2107 throttle actuator module processor.No pats codes.

Various can codes on other systems.

Checked pedal voltages, no1 0.3 - 3 volts
no2 0.7 - 6.9 v (seems high), smoke tested intake and ok.reference voltages to throttle motor ok , but ecu does not drive throttle flap.
If we carefully operate flap ecu sees voltages on live data and idles ok.
removed / cleaned ecu earths under air filter, ecu connections look ok.

my next step is to get ecu software done but local dealer cant do it for 2 weeks

Ford technical not a great help, any furthur tests ? or should i send ecu off for testing.

any thoughts appreciated.

Joe
