NOTICE:
ºColdº and ºHot in these sentences express the tempera-
ture of the sensors themselves. ºColdº is from ± 10°C
(14°F) to 50°C (122°F) and ºHotº is from 50 °C (122°F) to
100°C (212°F).
1. REMOVE THROTTLE BODY COVER
2. REMOVE INTAKE MANIFOLD ASSEMBLY
(See page EM±36)
3. INSPECT VVT SENSOR RESISTANCE
(a) Disconnect the VVT sensor connector.
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance:
Cold835 to 1,400 W
Hot1,060 to 1,645 W
If the resistance is not as specified, replace the sensor.
(c) Reconnect the VVT sensor connector.
(d) Connect the VVT sensor connector.
4. REINSTALL INTAKE MANIFOLD ASSEMBLY
(See page EM±60)

INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT HAND±HELD TESTER
(a) Connect a hand±held tester to the Controller Area Net-
work Vehicle Interface Module (CAN VIM). Then connect
the CAN VIM to the Date Link Connector 3 (DLC3).
(b) Please refer to the hand±held tester operator's manual
for further details.
3. INSPECT FUEL CUTOFF RPM OPERATION
(a) Increase the engine speed to at least 2,500 rpm.
(b) Check for injector operating noise.
(c) Check that when the throttle lever is released, injector op-
eration noise stops momentarily and then resumes.
HINT:
The vehicle should be stopped.
Measure with the A/C OFF.
Fuel return speed: 1,400 rpm
(d) Disconnect the hand±held tester and CAN VIM from the
DLC3.
