2GR-FE ENGINE CONTROL SYSTEM
– SFI SYSTEM
ES–47
ES
(h) WAVEFORM 8
(1) Vehicle speed signal
HINT:
•
The wavelength becomes shorter as the
vehicle speed increases.
•
Depending on the vehicle, the output
waveform voltage may rise to 12 V if
influenced by optionally installed systems.
(i)
WAVEFORM 9
(1) Throttle drive motor operation signal (positive
terminal)
HINT:
The duty ratio varies depending on the throttle
actuator operation.
(j)
WAVEFORM 10
(1) Throttle drive motor operation signal (negative
terminal)
HINT:
The duty ratio varies depending on the throttle
actuator operation.
(k) WAVEFORM 11
(1) Engine speed signal
HINT:
The wavelength becomes shorter as the engine
rpm increases.
