Intake Air Temperature Sensor: Testing and Inspection
TROUBLESHOOTING HINTS
Because the intake air temperature of the intake air in the air cleaner, it indicates a temperature different than the temperature of the outside air
when the engine is running.
Note that the resistance of the intake air temperature sensor decreases when the temperature of the intake air increases.
-
The intake air temperature sensor terminal voltage becomes higher when the resistance of the intake air temperature sensor increases, and becomes
lower when the resistance decreases. Consequently, the intake air temperature sensor terminal voltage varies in accordance with the temperature of
the intake air, becoming lower when the temperature of the intake air increases.
INSPECTION
Using Scan Tool
HARNESS INSPECTION
STEP 1. Check for continuity in the ground circuit.
-
Volume air flow sensor connector: Disconnected
OK: GO TO STEP 2
NG: Repair the harness. (A5 - 92)
STEP 2. Check for an open or short-circuit between the intake air temperature sensor and the engine control module.
-
Volume air flow sensor connector: Disconnected
-
Engine control module connector: Disconnected
OK: GO TO STEP 3
NG: Repair the harness. (A6 - 72)
