I have a 1 ton 99 dog diesel and it has no power I have done everything except change the APPS can you help? Measured 7 new apps they all measure into the meg ohms contact should be <125 ohms
what codes could come up?
I need tech info on what this will do either to or for the ECM with extremely high resistance
I would like electrical specs for the APPS
what extremely high resustance can you turn on transistors ont that high resistance with resistance that much above specs

accelerator pedal idle validation circuit resistance for on and off - idle states
Maximum closed circuit resistance <125 ohms
Minimum open circuit resistance >1 k ohms
between supply and return wires 2000 to 3000 ohms
between supply and signal wires
(released pedal 1500 to 3000 ohms)
beween supply and signal wires ( depreased pedal) 200 to 1500 ohms
Note: released resistance must be 1000 ohms
This is Cummins info?????????

Can you turn on a transistor with this kind of exccessively high resistance?
