4. INSPECT ENGINE COOLANT TEMPERATURE
SENSOR
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween each terminal.
Resistance:
Approx. 20C (68F) 2.32 to 2.59k
Approx. 80C (176F) 0.310 to 0.326k
NOTICE:
In case of checking the water temperature sensor in the wa-
ter, be careful not to allow water to go into the terminals,
and after checking, wipe out the sensor.
5. INSPECT KNOCK SENSOR
(a) Using an ohmmeter, measure the resistance between ter-
minals.
Resistance: 120 to 280 kat 20C (68F)
HINT:
If the resistance is not specified, replace the sensor.
6. INSPECT EFI RELAY
(a) Inspect the relay continuity.
(1) Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
Specified condition: Continuity
(2) Check that there is no continuity between terminals
3 and 5.
Specified condition: No continuity
(b) Inspect the relay operation.
(1) Apply battery voltage across terminals 1 and 2.
(2) Using an ohmmeter, check that there is continuity
between terminals 3 and 5.
Specified condition: Continuity

2.INSPECT POWER STEERING OIL PRESSURE SEN- SOR
(a)Using a voltmeter, measure the voltage between termi-
nals PSW and E2.
Voltage:
ConditionVoltage (V)
Not spin the steering wheel at engine idling9 to 14
Spin the steering wheel at engine idling0 to 3
3.INSPECT THROTTLE BODY
(a)Inspect the throttle control motor for operating sound.(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 operation is not as specified, check the throttle control motor (See page 10±39), wiring and ECM.
(b) Inspect the throttle position sensor.
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When turning the accelerator pedal position sensor lever to the full±\
open position, check thatthe throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA shown the
standard value.
Standard throttle valve opening percentage:
60 % or more
If operation is not as specified, check that the accelerator pedal positio\
n sensor (See page 10±39), wiring
and ECM.
If you have no hand±held tester, measure voltage between terminals (VTA1 ± E2, VTA2 ± E2) of the ECM
connector (See page 05±318).
(c) Inspect the air assist system.
(1) Start the engine and check that the CHK ENG does not light up.
(2) Allow the engine to warm up to normal operating temperature.
(3) Turn the A/C compressor ON to OFF, and check the idle speed.
Idle speed (Transmission in neutral): 700 50 rpm
NOTICE:
Perform inspection under condition without electrical load.
(d) After checking the above (b) to (d), perform the driving test and check that there is no sense of incon-
gruity.
4. INSPECT ACCELERATOR PEDAL POSITION SENSOR
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Check that the voltage (ACCEL POS) of the CURRENT DATA shown the standard value.
Accelerator pedal released: 0.5 to 1.1 V
Accelerator pedal depress: 2.6 to 4.5 V
(d) Check that the voltage (ACCEL POS #2) of the CURRENT DATA shown the standard value. Accelerator pedal released: 1.2 to 2.0 V
Accelerator pedal depress: 3.4 to 5.3 V
If you have no hand±held tester, measure voltage between terminals (VPA ± EPA, VPA2 ± EPA2) of the ECM
connector (See page 05±318).
