Got a 450clc sn ff450cx091828 Has codes"accelerator position 3- voltage below normal or shorted to low source", "fuel delivery pressure below range". I replaced the throttle dial with no luck and replaced the fuel pressure sensor but still won't clear the codes. On the scanner the accelerator position only goes up to 80% at full throttle. The machine was going into limp mode and the hydraulics when operated would sometimes bog the machine and stall it. Any ideas? Thank you.
Please supply the specific code numbers.
I don't have John Deere numbers only jpro numbers.
mg2361 is looking for the complete code number , SPN and FMI. Is there another column of numbers just to the right of the “ Lookup code” column?
From top to bottom- fmi 3, 4, 4, for the active ones.
28.04 throttle reference low could be the reference voltage wire to the dial is shorted to ground. Or the wire from the PVC to the ECU is shorted to ground. Another possibility is the ECU compares ground voltage to the PVC's ground to help calculate the throttle dial voltage through a resistor. You may want to check that resistor (located near the ECU). 94.04 input voltage low could be short to ground on the input wire from the sensor to the ECU. Did you try to clear the codes through the DDU mounted near the ECU? Check you messages.
DDU is the gauge with the two arrow buttons? How do you clear it? Will check it out monday I appreciate all the help!!
Also, where is the PVC located?
Correct. Check messages. PVC is behind the seat under the plastic.
