a. Connect the pocket tester (Ω × 100/× 1 kΩ) to
the coolant temperature sensor terminals as
shown.
b. Immerse the coolant temperature sensor “1”
in a container filled with coolant “2”.
TIP
Make sure that the coolant temperature sensor
terminals do not get wet.
c. Place a thermometer “3” in the coolant.
d. Heat the coolant or let it cool down to the
specified temperatures.
e. Measure the coolant temperature sensor re-
sistance.

CHECKING THE THROTTLE POSITION
SENSOR
1. Remove:
• Throttle position sensor
(from the throttle bodies)
WARNING
EWA1MC1002
• Handle the throttle position sensor with
special care.
• Never subject the throttle position sensor
to strong shocks. If the throttle position
sensor is dropped, replace it.
2. Check:
• Throttle position sensor maximum resistance
Out of specification → Replace the throttle
position sensor.

a. Connect the pocket tester (Ω × 1k) to the
throttle position sensor terminals as shown.
b. Measure the throttle position sensor maxi-
mum resistance.
