Throttle Sensor (Service Code/Character-11/tPS)
•
Adjust the throttle sensor positioning as follows.
○
Install the air filter temporarily.
○
After warming up the engine, check the idling speed.
Idle Speed
Standard: 1 300 ±100 r/min (rpm)
○
Stop the engine and turn the ignition switch OFF.
○
Disconnect the throttle sensor connector and connect the
throttle sensor setting adapter [A] between the harness
connector and throttle sensor connector.
○
Connect a digital meter to the sensor setting adapter
leads.

Throttle S ensor Output Voltage
Connections to Sensor
Meter (+)→ G/W lead
Meter (–)→ BK/W lead
○
Start the engine with idle speed.
○
Turn [A] the throttle sensor and bring the sensor output
voltage within the standard range.
Output Voltage at Sensor
Standard: 1.08 ∼ 1.18 V DC (at idle throttle opening)
○
Tighten the throttle sensor mounting screws.
Torque - Throttle Sensor Mounting Screws: 2.0 N·m (0.20
kgm·f, 18 in·lb)
○
Recheck the sensor output voltage is within the standard
range.
○
Stop the engine and turn the ignition switch OFF.
○
Remove the setting adapter and reconnect the throttle
sensor connector.
Input Voltage Inspection
NOTE
○
Be sure the battery is fully charged.
•
