Signal Wave Form & Data

When checking TPS wave form, it is strongly recommended to examine wave form with MAP sensor wave form.

1. Period (1) is the voltage of MAP in idling and 0.8~1.2V, and there must be a little fluctuation in wave form.
2. The voltage in Period (2) is 0.3~1.0V in average.
3. Period (3) is in W.O.T and the voltage there is 4.3V, and MAP sensor voltage is about 4.3V.
