ON–VEHICLE INSPECTION
1.
INSPECT CAMSHAFT TIMING OIL CONTROL VALVE
RESISTANCE
(a)
Disconnect the oil control valve connector.
(b)
Using an ohmmeter, measure the resistance between the
terminals.
Resistance: 5.5 – 12
Ω
at 20
°
C (68
°
F)
If the resistance is not as specified, replace the valve.
(c)
Reconnect the oil control valve connector.
2.
INSPECT VVT–i OPERATION
(a)
Allow the engine to warm up to normal operating tempera-
ture.
(b)
Check that the engine stalls or becomes in rough–idling
state when the battery positive voltage is applied to the oil
control valve with the engine idling.
If operation is not as specified, check the oil control valve (see
page
), VVT–i pulley, intake camshaft, wiring and ECM.

ON–VEHICLE INSPECTION
1.
REMOVE ENGINE COVER
Remove the 4 nuts and engine cover.
2.
CONNECT VACUUM GAUGE
Using a 3–way connector, connect vacuum gauge to the hose
between the actuator and VSV.
3.
START ENGINE
4.
INSPECT INTAKE AIR CONTROL VALVE
(a)
While the engine is idling, check that the vacuum gauge
needle does not move.
(b)
Rapidly depress the accelerator pedal to fully open posi-
tion and check that the vacuum gauge needle momentari-
ly fluctuates approx. 33.3 kPa (250 mmHg, 9.84 in.Hg) or
more. (The actuator rod is pulled down.)
5.
REMOVE VACUUM GAUGE
Remove the vacuum gauge, and reconnect the vacuum hoses
to their proper locations.
6.
REINSTALL ENGINE COVER
