2006 250 hpdi idle adjustment

[phillic]

Can anyone tell me where this adjustment is made at or can it be made at all without hooking up to a computer? Mine is idling at 900 rpms after a visit to the shop for a sync and link and needs to come down. It is along way back to the shop so I would rather do it myself. I'm not yet familiar with the HPDI fuel system but plan to get there. thks

there is no idle adjustment.
either all the linkage and the TPS is set correctly or its broke.

the tps adjustment is in the service manual.
all you need is a voltage meter and the adapter that is used for setting the TPS.

i would bring it back to the shop
could be that your tps is set in range.
so they can check other things out.
tps doesnt change (move) just on its own.
the voltage could change that is send to the tps.


operating temp normal ?
