Its weekend, time for a new MS issue.
I tried to calibrate my TPS, but it always reads 254.
I changed the wiring and the sensor itself.
Cables are OK and both sensors read the same values.
When I connect the sensor I just get 5V (reading 254) in the MS.
When I ground the MS input from the TPS sensor, I get 0V on the MS.
When I isolate the MS input the voltage builds up slowly, like a capacitor charging.
