TPS sensor- reading off
I was just curious if this was normal, important, and/or fixable? My TPS (Throttle Position Sensor) sensor on a 1998 E150 4.2l auto, is reading 20% when it should be reading 0%. I verified that the throttle body is closed when the pedal is not depressed. Also, the TPS reads 93.7% when I have it at full throttle. This I did not verify because I was by myself and more concerned with the lower reading.
Any thoughts?

Consult Ford's OBDII Emissions handbook for details if you have further curiosity.

Dead spots anywhere through the TPS range is the usual problem. Often the rheostat (TPS) develops a dead spot at the heavily used parked position & idle quality will suffer. I had a TPS that had an intermittent fritzing microconnection inside at the carbon strip that made the motor stumble badly at any speed occasionally.
If these simple rheostats go smoothly from their lowest to highest range you're usually good to go, the computer is able to make minor adjustments to compensate.

Well this van does idle a little rough and sometimes if you are driving at, what should be, 10% throttle it likes to run rough. Almost a galloping, if that makes sense. I guess it just seems weird because the other Fords I have worked on read 0 when the TB is closed...
