Question about Ford E-250
Hello! The Throttle Positioning Sensor (TPS) is defective...It is bolted to the throttle body...It is a round black device about the size of a 1/2 dollar, with a mounting hole on each side...It has a 3 wire connector...Wire colors are...Gray/White...Gray/Red...And Brown/White...Cost $55...Use 2 safety pins...Push the pointed end into the rear of the connector on the Gray/White wire and the other on the Gray/Red wire...Do not disconnect the connector...Set a volt meter to read a maximum of 5 volts...Place the + probe on the Gray/White wire...The - probe on the Gray/Red...Turn the key to on...Voltage must be less then 1 volt (.85)...If not TPS is defective...
Do not move probes...Start the engine (if you can)...Watch the meter...Slowly increase the throttle...Voltage must rise to 4 volts (wide open throttle)...As voltage rises...If the voltage skips, jumps, or acts erratic the TPS is defective...

The wot (wide open throttle switch) is connected to a flap in the air filter to intake pipe you will see it just inside the aluminum intake opening (once you remove the rubber air filter hose.) the voltage varies with the position of the flap you probably need to use wd40 on the flap shaft to make in move easily and, report the correct voltage to the engine computer.
