Question

2000 Ford E350 5.4L, the vehicle will not move unless the gas pedal is held clear to the floor and I got the code P0720

Answer 1

HI there,

This code is for the OSS (output speed shaft) sensor. This is mounted in the tailshaft housing of the transmission and could possibly cause this issue. However, it could also mean there is internal damage to the transmission as well, so I would drop the transmission pan and check for debris before replacing the sensor.

Answer 2

P0720 Ford Code - Output Shaft Speed Sensor Circuit Malfunction
