FUEL SYSTEM (DFI) 3-29
Throttle Sensor (Service Code/Character-11/tPS)
•
Turn the ignition switch ON and push the lanyard k ey un-
der the stop button.
•
Pushing the start button, run the engine 5 ∼ 6 seconds at
idling to measure the sensor input voltage.
○
Wait 15 seconds before using the starter again.
Input Voltage at ECU
Standard: 4.75 ∼ 5.25 V DC
•
Turn the ignition switch OFF.
If the reading of input voltage is less than the standard,
check the ECU for its ground, power supply and wiring
shorted. If the ground, power supply and wiring are good,
replace the ECU.
If the input voltage is within the standard range, check the
input voltage at the throttle sensor connector.
•
Remove the air filter temporarily (see Air Filter Removal).
•
Disconnect the throttle sensor connector and connect the
setting adapter [A] between the harness connector and
throttle sensor connector.
•
Connect a digital meter to the setting adapter leads.

Turn the ignition switch OFF.
If the reading is out of the range, check the wiring (see
wiring diagram in this section).
If the reading is good, check the output voltage of the
sensor.
