Hi 2005 Volvo VNL ISX 450 Engine...
Hi
2005 Volvo VNL ISX 450
Engine starts, idles but Have no throttle response
This has happened frequently. Every time was reset via pulling dashboard fuses, and engine fuses obove battery, or disconnecting battery altogether, but slways worked.
Last timr it fid not work gor 2 days, the worked by disconnecting batteries.
This time also, it has not worked and it has been several hours.
Check Engine ECU has been on for several years but has hsf no illeffe t.
This time as well as last yime, addiyional Check Light Conttol Module is on. Looks like this is the active fault prevrnting the throttle response.
It is dark where I am now, wekend and no nonVolvo shop knows anyghi g about this.
Aski g me to trace wiring schenatics or check harness eon't help. I can't dive into the engine and chase hundred possible faults.
ECU J1939 data link is on but it has been on for several years
Light Control Module J1939 is on. MID 144 MID 216. PSID 201. FMI9
