THROTTLE BODY ASSEMBLY

DISASSEMBLY AND ASSEMBLY

Disassembly Steps 1 - 6:

REASSEMBLY SERVICE POINTS

>>A<< THROTTLE POSITION SENSOR (TPS) INSTALLATION




1. Place the TPS in the throttle body in the position shown in (1) of the drawing.
2. Turn the TPS to the position shown in (2) of the drawing. Connect a circuit tester between terminal 2 (TPS output) and terminal 4 (earth) of the TPS to measure the output voltage. Turn the TPS to a position where the output voltage is within the standard value range, and secure the TPS there by tightening the screw.

Standard value 0.535 - 0.735 V




3. After tightening the screw, check the output voltage again. If the voltage is out of the standard value range, loosen the screw and adjust the TPS position for a proper output voltage, then tighten the screw. If necessary, repeat the adjustment until a correct voltage is reached.
4. Connect a circuit tester between terminal 1 (TPS power supply) and terminal 2 (TPS output). Check that the resistance reading varies smoothly as the throttle valve is moved slowly to the wide open position.
