(3) Connect a circuit tester between 4 (ground) and 2 (output),

or between 2 (output) and 1 (power). Then, make sure that

the resistance changes smoothly when the throttle valve is
slowly moved to the fully open position.

(4) Check for continuity across terminals 3 (closed throttle

position switch) and 4 (ground) with the throttle valve both
fully closed and fully open.

If there is no continuity with the throttle valve fully closed,

turn TPS counterclockwise, and then check again.

NOTE

Some throttle position sensors are not provided with the
position switch. In that case, the check described in step (4)
cannot be accomplished.

(5) If the above specifications are not met, replace TPS.

 

 SENSOR (TPS)

 SOHC for MONTERO and TRUCK

 Install the throttle position sensor to the throttle body as

shown in the illustration.

(2) Turn the throttle position sensor 90” counterclockwise to

set it, and tighten the screws.

(3) Connect a circuit tester between 

 (ground) and 

(output), or between 

 (output) and

make sure that the resistance changes smoothly when the

throttle valve is slowly moved to the fully open position.

(4) Check for continuity across terminals
