Removal
Drain the coolant.
Remove the air filter.
Remove the throttle body in the sequence shown in the figure.
Installing the Throttle Body Gasket
Position the gasket so that its protruding part is located as shown in the figure, and then install it between the intake manifold and the throttle body.
Installing the Throttle Position Sensor (TPS)
Install the throttle position sensor in the position shown in the figure and tighten the mounting screws.
Connect a multimeter between terminal 1 (TPS power supply) and terminal 2 (TPS output) of the throttle position sensor connector, and check that the resistance gradually increases when the throttle valve is slowly opened (until it is fully opened).
On vehicles without the TCL system, check the circuit between terminal 3 (closed throttle position switch) and terminal 4 (ground) of the throttle position sensor connector with the throttle valve fully closed and fully open.
If the circuit is open when the throttle is fully closed, turn the throttle position sensor housing counterclockwise and repeat the test.
If there is a malfunction in the sensor, replace the throttle position sensor.
In good condition
