3-80 FUEL SYSTEM (DFI)
Subthrottle Sensor (Service Code 32) (DTC P0220, P0223)
(Checking wire for short circuit to ground)
• Check the wiring for short circuit to ground by checking
  continuity between the sensor connector [A] and frame
  ground [B].
    Wiring Continuity Inspection
     BL/W lead (ECU terminal 28) [C] ← → Frame Ground
    If there is continuity, repair or replace the main harness.
    If there is no continuity, check the sensor for internal short
    circuit.

(Checking sensor for internal short circuit)
• Connect the setting adapter [A] to the sensor connector
  only.
    Special Tool - Throttle Sensor Setting Adapter:        57001
                      -1538
• Measure the subthrottle sensor resistance.
    Subthrottle Sensor Resistance
      Connections to Adapter:
        Digital Meter (+) → R (sensor BL) lead
        Digital Meter (–) → BK (sensor G) lead

      Standard:      4 ∼ 6 kΩ
    If the reading is out of the standard, replace the throttle
    body assy.

• Remove:
   Right Side Cover (see Side Cover Removal in the Frame
   chapter)
• Disconnect the subthrottle sensor connector and connect
  the setting adapter [A] between the connectors.
