CHECKING THE COOLANT TEMPERATURE
SENSOR
1. Remove:
•
Coolant temperature sensor
WARNING
EWA14130
• Handle the coolant temperature sensor
with special care.
• Never subject the coolant temperature sen-
sor to strong shocks. If the coolant temper-
ature sensor is dropped, replace it.
2. Check:
•
Coolant temperature sensor resistance
Out of specification
Replace.
a. Connect the digital circuit tester (
) to the
coolant temperature sensor.
b. Immerse the coolant temperature sensor
in a container filled with coolant.
TIP
Make sure the coolant temperature sensor ter-
minals do not get wet.
c. Place a thermometer in the coolant.
d. Slowly heat the coolant, and then let it cool
to the specified temperature indicated in
the table.
e. Check the coolant temperature sensor for
continuity at the temperatures indicated in
the table.

CHECKING THE THROTTLE POSITION
SENSOR INPUT VOLTAGE
1. Check:
•
Throttle position sensor input voltage
Out of specification
Replace the ECU.
a. Connect the test harness S– pressure
sensor (3P) to the throttle position sensor
coupler and the wire harness.
b. Connect the digital circuit tester (DCV) to
the test harness S– pressure sensor (3P).
