Montero LS 4WD V6-2972cc 3.0L SOHC 24 Valve (1996)
sensor, it passes through the intake air temperature sensor, which is a type of resistor, and is grounded as the engine control module.
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.
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.
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)
