ON-VEHICLE INSPECTION
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE
ASSY
(a) Check the operation.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Start the engine and allow it to warm up.
(4) Connect the hand-held tester, then select VVT from
the ACTIVE TEST menu.
(5) Check the engine speed when the OCV is operated
with the hand-held tester.
Standard:
Tester OperationSpecified Condition
OCV is OFFNormal engine speed
OCV is ONRough idle or engine stall
If the operation is not as specified, inspect the camshaft timing
oil control valve (see page 10-2).
2. INSPECT THROTTLE BODY ASSY
(a) Check the operation (throttle control motor).
(1) Turn the ignition switch ON.
(2) When turning the accelerator pedal position sensor
lever, check the running sound of the motor. Also,
check that there is no friction sound.
If the operation is not as specified, inspect the throttle body (see
page 10-2).
(b) Check the operation (throttle position sensor).
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Check that the check engine warning light does not
light up.
(4) Check that the throttle valve opening percentage
(THROTTLE POS) of CURRENT DATA showns the
standard value.
Standard throttle valve opening percentage:
60 % or more
NOTICE:
When checking the standard throttle valve opening per-
centage, the transmission is in the neutral position.
3. INSPECT ACCELERATOR PEDAL POSITION SENSOR
(a) Inspect the voltage.
(1) After turning the ignition switch ON, check CURRENT DATA, then verify that the throttle position
sensor voltage is within the standard value.
Standard voltage: 0.6 to 1.0 V
If the voltage is not as specified, inspect the accelerator pedal (see page 10-2).

INSPECTION
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE
ASSY
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
1 (-) - 2 (+)6.9 to 7.9 W at 20C (68F)
If the resistance is not as specified, replace the camshaft timing
oil control valve.
(b) Check the operation.
(1) Connect the positive (+) lead from the battery to ter-
minal 2 (+) and negative (-) lead to terminal 1 (-),
then check the movement of the spool valve.
NOTICE:
Confirm that the spool valve moves freely and does not get
stuck in any position.
HINT:
Bad returning of the spool valve resulted from catching foreign
objects causes subtle pressure leak to the advanced direction.
In that case, DTC can be detected.
2. INSPECT MASS AIR FLOW METER
(a) Check the operation.
(1) Apply battery voltage across terminals 1 (+B) and 2
(E2G).
(2) Using voltmeter, connect the positive (+) tester
probe to terminal 3 (VC), and negative (-) tester
probe to terminal 2 (E2G).
(3) Blow air into the mass air flow sensor, then check
that the voltage fluctuates.
If the operation is not as specified, replace the mass air flow
sensor.

sensor.
3. INSPECT ENGINE COOLANT TEMPERATURE
SENSOR
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
1 (E2) - 2 (THW)2.32 to 2.59 kW at 20C (68F)
1 (E2) - 2 (THW)0.310 to 0.326 kW at 80C (176F)
NOTICE:
When checking the engine coolant temperature sensor in
water, be careful not to allow water to intrude into the termi-
nals. Then dry the engine coolant temperature sensor after
checking.
If the resistance is not as specified, replace the engine coolant
temperature sensor.
