CHECKING THE INTAKE AIR
TEMPERATURE SENSOR
1. Remove:
• Intake air temperature sensor
EWA14110
• Handle the intake air temperature sensor
with special care.
• Never subject the intake air temperature
sensor to strong shocks. If the intake air
temperature sensor is dropped, replace it.
2. Check:
• Intake air temperature sensor resistance
Out of specification Replace.
a. Connect the digital circuit tester () to the
intake air temperature sensor terminal as
shown.
b. Immerse the intake air temperature sensor
“1” in a container filled with water “2”.
Make sure that the intake air temperature sensor
terminals do not get wet.
c. Place a thermometer “3” in the water.
d. Heat the water or let it cool down to the
specified temperatures.
e. Measure the intake air temperature sensor
resistance.
3. Install:
• Intake air temperature sensor
EAS30681
CHECKING THE FUEL INJECTOR
1. Check:
• Fuel injector resistance
Out of specification Replace the fuel injec-
tor.
a. Disconnect the fuel injector coupler from
wire harness.
b. Connect the digital circuit tester () to the
fuel injector coupler.
c. Measure the fuel injector resistance.
