FUEL SYSTEM (DFI) 3-31
Throttle Sensor (Service Code/Character-11/tPS)
•
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.
Special Tool - Throttle Sensor Setting Adapter: 57001
-1521
Throttle Sensor Output Voltage
Connections to Sensor
Meter (+) → G/W lead
Meter (–) → BK/W lead
•
Measure the sensor output voltage with the idle speed.
Output Voltage at Sensor
Standard: 1.08 ∼ 1.18 V DC (at idle throttle opening)
CAUTION
Never drop the throttle sensor, especially on a hard
surface. A shock to the sensor can damage it.
•
After throttle sensor voltage inspection, remove the set-
ting adapter.
If the reading is out of the standard range, inspect the
throttle sensor resistance.
If the output voltage is normal, check the wiring for conti-
nuity (see next diagram).
Resistance Inspection
•
Turn the ignition switch OFF.
•
Remove:
Air Filter (see Air Filter Removal)
•
Disconnect the throttle sensor connector and connect the
setting adapter [A] to the throttle sensor [B].

○
Do not connect the harness connector.
•
Connect a digital meter [C] to the harness adapter leads.
•
Measure the throttle sensor resistance.
Throttle Sensor Resistance
Connections to
Harness Adapter: R lead [D] ←→ BK/BL lead [E]
Standard:
4 ∼ 6 kΩ
If the reading is out of the range, replace the throttle body
assy.
If the reading is within the range, but the problem still
exists, replace the ECU.
