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 7.9at 20_C (68_F)
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
stick in any position.
HINT:
Bad returning of the spool valve resulted from catching foreign
objects cause subtle 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 a voltmeter, connect the positive (+) tester
probe to terminal 3(VG), and negative (−) tester
probe to terminal 2 (E2G).
(3) Blow air into the mass air flow meter, then check that
the voltage fluctuates.
If the operation is not as specified, replace the mass air flow me-
ter.

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 kat 20_C (68_F)
1 (E2)−2 (THW)0.310 to 0.326 kat 80_C (176_F)
NOTICE:
In case of checking the engine coolant temperature sensor
in water, be careful not to allow water to go into the termi-
nals, and after checking, dry the engine coolant tempera-
ture sensor.
If the resistance is not as specified, replace the engine coolant
temperature sensor.

If the resistance is not as specified, replace the throttle body.
5. INSPECT KNOCK SENSOR
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
1 (Ground)−2 (Output)120 to 280 kat 20_C (68_F)
If the resistance is not specified, replace the knock sensor.
6. INSPECT ACCELERATOR PEDAL ROD ASSY

(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
3 (EP1)−6 (VCP1)2.25 to 4.75 k
1 (EP2)−4 (VCP2)2.25 to 4.75 k
If the resistance is not as specified, replace the accelerator ped-
al rod.
(b) Inspect the voltmeter.
(1) Using a voltmeter, measure the voltage between
the terminals.
Standard:
Tester ConnectionSpecified Condition
3 (EP1)−5 (VPA1)0.4 to 4.6 V
1 (EP2)−2 (VPA2)0.9 to 4.7 V
If the voltage is not as specified, replace the accelerator pedal
rod.

KICK DOWN SWITCH CIRCUIT
CIRCUIT DESCRIPTION
The kick−down switch is turned ON when the accelerator pedal is fully depressed and a signal is sent to the
ECM.
When the kick−down switch is turned ON, the ECM controls gear shifting according to the programmed shift
diagrams.
If a short circuit develops in the kick−down switch, the ECM disregards the kick−down signals and controls
shifting at the normal shift points.
