Montero LS 4WD V6-2972cc 3.0L SOHC 24 Valve (1996)
INSPECTION
Using Scan Tool
NOTE:
The closed throttle position switch normally turns off when the voltage of the throttle position sensor is 50 - 100 mV higher than the voltage at the
idle position. If the closed throttle position switch turns buck on after the throttle position sensor voltage has risen by 100 mV and the throttle
valve has opened the closed throttle position switch and the throttle position sensor need to be adjusted.
HARNESS INSPECTION
STEP 1. Check for an open or short-circuit between the closed throttle position switch and the engine control module.
-
Engine control module connector: Disconnected
-

OK: GO TO STEP 2
NG: Repair the harness. (A2 - 87)
STEP 2. Check for continuity in the ground circuit.
-
Throttle position sensor connector: Disconnected
OK: GO TO STEP 3
NG: Repair the harness. (A1 - 92)
STEP 3. Measure the power supply voltage of the closed throttle position switch.
-
Throttle position sensor connector: Disconnected
-
Engine control module connector: Connected
-
