MASS AIRFLOW
[g·m/s]
Indicates the mass air flow computed by
ECM according to the signal voltage of
the mass air flow sensor.
PURG VOL C/V
[%]

Indicates the EVAP canister purge vol-
ume control solenoid valve control value
computed by the ECM according to the
input signals.

The opening becomes larger as the value
increases.
INT/V TIM (B1)

Indicates [ °CA] of intake camshaft
advanced angle.
INT/V TIM (B2)
[ ° CA]
INT/V SOL (B1) [%]

The control value of the intake valve tim-
ing control solenoid valve (determined by
ECM according to the input signals) is
indicated.

The advance angle becomes larger as
the value increases.
INT/V SOL (B2) [%]
VIAS S/V
[ON/OFF]

The control condition of the VIAS control
solenoid valve (determined by ECM
according to the input signals) is indi-
cated.

OFF: VIAS control solenoid valve is not
operating.
