TPS voltage at WOT

[asianjedi]

I changed up my setup to one unit that has a window switch and throttle position switch combined into one.

This new unit tells me the voltage at WOT where my previous one did not.

It says that the voltage at WOT is 3.8. Is this correct? I thought it was 4.2.

Does anyone know?

BTW, I tapped into the white wire in the plastic tube that runs along the fuel rails to get my TPS reading.

Not sure about the S54, but my M54 engine MS43 ECU shows 0.48 V closed to 4.40 V WOT. There are 2 TPS sensors for redundancy. The other sensor is a complement of the first to 5 V (e.g. TPS1=0.48V; TPS2=4.52V).

It should be closer to 5 volts than 3.8v I would think.

I thought that as well but Tazam3 said he tested it at 3.X something. Hmmmm.
