I measured voltage with motor on. Voltage from ground to green/white wire changes if rev up the engine. Is this normal?

Thanks for your replies.

Could anyone explain what the green/white wire is on a TPS sensor. After trying to adjust the TPS 0.45V it changes to 0.5 or 0.6 because voltage from this wire to ground changes frequently. TPS itself is not changing its resistance.
