Remove the remote accelerator position sensor from the accelerator pedal assembly. Note sensor orientation in the accelerator pedal assembly, and the sensor pigtail routing prior to sensor removal. Thoroughly inspect the pigtail for signs of abrasion.
Connect the multimeter that is capable of measuring a duty cycle between terminal C and terminal B of the breakout T.
Turn the keyswitch to the ON position.
Display the duty cycle output of the remote accelerator position sensor while the sensor slot is released. Use a screwdriver to advance the sensor slot to the maximum position.When the sensor is removed from the accelerator pedal assembly and the sensor slot is released, the correct duty cycle is 10 percent or less. When the sensor slot is moved to the maximum position, the correct duty cycle increases to 90 percent or more.Note: When the sensor is removed from the accelerator pedal assembly the following diagnostic codes may be generated:
30-13 PTO Throttle out of calibrationThe diagnostic code should disappear when the sensor is properly assembled back into the accelerator pedal assembly.
Turn the keyswitch to the OFF position.Expected Result:The measured duty cycle for the
