CHECKING THE INTAKE AIR
TEMPERATURE SENSOR
1. Remove:
• Intake air temperature sensor
EWA1TP1020
WARNING
• 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.
Intake air temperature sensor re-
sistance
5.4–6.6 kΩ at 0 °C (32 °F)
290–390 Ω at 80 °C (176 °F)
