Sienna FWD V6-3.5L (2GR-FE) (2009)
(f) WAVEFORM 6
(1) Variable Valve Timing (VVT) sensor signal (1)
(2) Crankshaft position sensor signal (2)
HINT: The wavelength becomes shorter as the engine rpm increases.
(g) WAVEFORM 7
(1) Igniter IGT signal (from ECM to igniter) (1)
(2) Igniter IGF signal (from igniter to ECM) (2)
HINT: The wavelength becomes shorter as the engine rpm increases.
(h) WAVEFORM 8
(1) Purge VSV for EVAP system operation signal
HINT: If the waveform is not similar to that shown in the illustration, check the waveform again after idling for 10 minutes or more.
