3. CHECK VVT SENSOR OUTPUT VOLTAGE
(a) Turn the ignition switch to the ON position.
(b) Check that the voltage between terminal VC1 of the ECM
and ground is 5 V.
HINT:
For the terminal arrangement of the ECM, see page DI−34.
(c) While turning the crankshaft pulley by hand, measure the
voltage between each terminal. Check that the voltage
changes between the Hi range and Lo range as shown in
the table below.
HINT:
For the terminal arrangement of the ECM, see page DI−34.
Terminal No.
VV1+ VV1−
VV2+ VV2−
4. INSPECT CRANKSHAFT POSITION SENSOR
(a) Using an ohmmeter, measure the resistance between the
terminals.
RESISTANCE:
1630 to 2740 Ω
2065 to 3225 Ω at hot
NOTICE:
"Cold" and "Hot" mean the temperature of the coils them-
selves. "Cold" is from −10_C (14_F) to 50_C (122_F) and
"Hot" is from 50°C (122_F) to 100_C (212_F).
