Back in July I lost ECM output for my lift pump. I tested for AC noise at that time and had no issue so I corrected and added a fused power source and now it runs off a switch. BTW alternator is believed to have the same milage as the chassis which is 332,732 Two weeks ago to transmission started having issues with torque converter clutch lock up it was hunting a lot. I threw a scanner on it and started collecting live data. I find out my accelerator pedal position sensor will not register over 80% at wide open throttle. At this point I was very confused so I started testing more things including A/C noise again and the alternator is still fine my batteries are fully charged and the app sensor is a 2 years old Mopar unit. I have recalibrated the sensor as well as removing battery cables over night. By the way my alternator putting out .01 volts ac occasionally it goes to .02 on the meter. Where do I go next how can I bench test the sensor it's self, then are the transmission problems from this sensor or something else?
