I think if you pull the connector you have to clear the codes??arthuy wrote: ↑Sun Mar 22, 2020 4:54 pmI have got the hang of the diagnostic LED now so thought would see if there was any clues to help my idle problem.
2 codes are:
4-1-1 Throttle valve sensor: signal faulty
2-2-3 Idle speed regulating valve: no signal or signal faulty
Suppose 4-1-1 will be oil in the sensor I have read about perhaps.
I will check the wiring on the ICV, I did change this with a spare and it does appear to be working as when I pull the wiring plug off it alters the engine speed.
Any hints would be great.
then try again?
