Question about 2001 Ford F350 Super Duty SuperCab
It indicates an insufficient output from the OSS sensor.The output shaft speed (OSS) sensor is a magnetic pickup that provides
transmission output shaft rotation speed information to the powertrain
control module (PCM).
I suspect RFI, affecting the OSS signal to the CPM. I will post the actual PCM rationality test, it will help you understand what the PCM looks for before setting the code.Possible sources of strong RFI are the alternator, Battery cables corroded, fuel pump faulty, and any other wire running next to the returning wiring harness, the return signal from the OSS signal is tied to your transmission solenoid, TSS, and a few other electrical systems, any of them will send an unwanted voltage that can interfere with the signal.
