If the STP sensor adjustment is necessary, measure the sensor
output voltage and adjust the STP sensor position as follows:
• Remove the air cleaner box . (5-14)
• Loosen the throttle body clamp screws at the intake pipe side.
• Lift up the throttle body assembly from the intake pipe.
• Disconnect the throttle cables from their drum.
• Disconnect the STVA lead wire coupler.
• Insert the needle pointed probes to the STP sensor coupler.
• Turn the ignition switch ON.
• Close the secondary throttle valve by finger, and measure the
STP sensor output voltage.
