REMOVAL PROCEDURE
1. Remove the bolt from the air inlet duct resonator to the air intake box.
2. Loosen the hose clamp on the resonator pipe and swing the pipe out of the way.
3. Disconnect the electrical connector from the Throttle Position (TP) sensor.
4. Remove the 2 screws and the IP sensor from the throttle body.
INSTALLATION PROCEDURE
1. Align the TP sensor (3) to the throttle body with the TP sensor's upper screw hole (1) slightly ahead of the hole on the throttle body (2). This will correctly engage the throttle lever tab with the TP sensor movement.
NOTE: Refer to Fastener Notice in Service Precautions.
2. Rotate the TP sensor (1) rearward in order to align the screw holes, and install the 2 screws.
Tighten
Tighten the screws to 2.0 N.m (18 lb in).
3. Connect the TP sensor electrical connector.
4. Attach the resonator pipe to the air intake box, and secure the pipe with one bolt.
