Hello!
I have trouble with fluctuating FPS value.

On cold engine in SManager i press "READ" in tab "Scale TPS"->"Minimum reading" - the value is 0.70% or 0.60%

On warmup engine "minimum reading" is 0 or 0.12%

it's normal?

IS this with an OEM or aftermarket TPS sensor? Is this an OEM or aftermarket Throttle body?

There may be a problem with either the throttle body or the TPS. Something may be loose on the throttle body which is changing at different temps, or it may just be worn and needs to be replaced.

You think is not wiring?
