FUEL SYSTEM (DFI) 3-81
Subthrottle Sensor (Service Code 32) (DTC P0220, P0223)

• Measure   the output voltage with the engine stopped and
  with the connector joined.
• Turn the ignition switch on.
  Output Voltage
   Standard:        DC 1.08 ∼ 1.12 V at subthrottle valve full
                    close position
                    DC 4.28 ∼ 4.73 V at subthrottle valve full
                    open position (for reference)

• Turn the ignition switch off.
 If the reading is DC 5 V or more, check the following part
 resistance.
○Disconnect the throttle setting adapter [A] from the main
 harness side.

  Part Resistance Inspection
    Connections to Adapter:
      Digital Meter (+) → R (sensor BL) lead
      Digital Meter (–) → W (sensor BL/W) lead
  If the reading is 0 Ω, replace the throttle body assy.
