Hint:
The standard normal voltage between each pair of the ECM terminals is shown in the table below. The appropriate conditions for checking each pair of the terminals are also indicated.
The check results should be compared with the standard normal voltage for that pair of terminals, listed in the "Specified Condition" column.
The illustration above can be used as a reference to identify the ECM terminal locations.
*1: The ECM terminal voltage is constant regardless of the output voltage from the sensor.
(a) WAVEFORM 1
(1) Camshaft Timing Oil Control Valve (OCV)
operation signal
HINT:
The wavelength becomes shorter as the engine rpm increases.

HINT:
The wavelength becomes shorter as the engine rpm increases.
(g) WAVEFORM 7
(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.
(h) WAVEFORM 8
(1) Vehicle speed signal
HINT:
(i) WAVEFORM 9
(1) Throttle drive motor operation signal (positive
terminal)
