Subthrottle Sensor (Service Code 32)
FUEL SYSTEM (DFI) 3-63
Output Voltage Inspection
• Remove the throttle body assy (see Throttle Body Assy
Removal).
• Measure the output voltage at the subthrottle sensor in
the same way as input voltage inspection. Note the following.
• Disconnect the subthrottle sensor (black) [A] and (black)
connect the harness adapter [B] between these connectors.
Special Tool - Throttle Sensor Harness Adapter :
57001–1538
• Measure the output voltage of the sensor with the engine
stopped, and with the connector joined.
Turn the ignition switch ON.
• Measure the output voltage when the subthrottle valve is
fully opened or completely closed by hand.
Main Throttle Sensor Output Voltage
Connections to Adapter
Meter (+) → W (sensor BR) lead
Meter (–) → BK (sensor BR/BK) lead
Standard :
0.48 ∼ 0.52 V DC (at idle throttle opening)
3.6 ∼ 3.8 V DC (at full throttle opening)
If the output voltage is out of the standard, inspect the
subthrottle sensor resistance.
If the output voltage is normal, check the wiring for continuity.
Wiring Connection
ECU Connector [A] ←→
Subthrottle Sensor Connector [B]
BR lead (ECU terminal 3)
BR/BK lead (ECU terminal 14)
If the wiring is good, check the ECU for its ground and
power supply (see ECU section).
