Probably the TPS itself is shot. Stick an ohm meter across it and you
can verify, but I doubt the link is lying. Garbage in, garbage out.

Subject: Odd Throttle Position Sensor numbers
I have noticed something odd with the TPS readings from my 97 FM2 with
Link ECU.
Here's a graph showing the TPS values when I go from no throttle to
pedal all the way down.

When my foot is off the throttle I see a reading of 10, as I start to
press the pedal the value actually drops then rises, which doesn't seem
right. Is this normal, or is my TPS failing, or is there some adjustment
I can make to avoid it settling in this strange area when my foot is off
the pedal ?
Simon.
