17-20 SELF-DIAGNOSIS SYSTEM
Throttle Position Sensor (Service Code 11) (DTC P0120, P0121, P0122, P0220,
P0223)
 If the reading is out of the standard, remove the ECU and
 check the wiring for continuity between harness connec-
 tors.
○Disconnect the ECU and sensor connectors.
  Wiring Continuity Inspection
   ECU Connector [A] ←→
      Throttle Position Sensor Connector [B]
        ECU Terminal 75 [C] ←→ Sensor Terminal [D]
        ECU Terminal 130 [E] ←→ Sensor Terminal [F]
  If the wiring is good, check the ECU for its ground and
  power supply (see ECU Power Supply Inspection(3-39)).
  If the ground and power supply are good, replace the
  ECU.
Throttle Position Sensor Output Voltage
Inspection
• Measure  the output voltage at the throttle position sensor
  in the same way as input voltage inspection, note the fol-
  lowing.
○Disconnect the throttle position sensor connector and
  connect the measuring adapter [A] between these con-
  nectors.

   Throttle Position Sensor [C]
   Digital Meter [D]
  Special Tool - Measuring Adapter: 57001-1700

  Throttle Position Sensor Output Voltage
    Connections to Adapters:
     (1) Digital Meter (+) → Y (sensor V) lead
            Digital Meter (–) → BK (sensor BK) lead
     (2) Digital Meter (+) → W (sensor V/W) lead
            Digital Meter (–) → BK (sensor BK) lead

• Measure   the output voltage with the engine stopped and
  with the connector joined.
• Turn the ignition switch on.
  Output Voltage
   Standard: (1) DC 4.4  4.6 V at full throttle opening
                 (for reference)
                  (2) DC 0.4  0.6 V at full throttle opening
                      (for reference)

                             NOTE
  ○Open the throttle, confirm the output voltage will be
   raise (drop).
  ○When the throttle is ordinary position, the standard
   value is not determined because there is some uncer-
   tain elements, e.g. water temperature, throttle valve
   initial opening, etc.

• Turn  the ignition switch off.
  If the reading is out of the standard, replace the throttle
  body assy.
