SELF-DIAGNOSIS SYSTEM 17-19
Throttle Position Sensor (Service Code 11) (DTC P0120, P0121, P0122, P0220,
P0223)
Throttle Position Sensor Removal
                          NOTICE
  Do not remove the throttle position sensor [A] since
  it has been adjusted and set with precision at the
  factory. Never drop the throttle body assy espe-
  cially on a hard surface. Such a shock to the throttle
  sensor can damage it.

Throttle Position Sensor Input Voltage Inspection
                            NOTE
  ○Be sure the battery is fully charged.
• Turn the ignition switch off.
• Right Side Cover (see Side Cover Removal(15-23))
  Remove:

• Disconnect:
   Throttle Position Sensor Connector [A]

• Connect the measuring adapter [A] to the throttle position
  sensor connectors as shown.
   Main Harness [B]
   Throttle Position Sensor [C]
  Special Tool - Measuring Adapter: 57001-1700
• Connect
  leads.
          a digital meter [D] to the measuring adapter

  Throttle Position Sensor Input Voltage
    Connections to Adapters:
      Digital Meter (+) → R (sensor W) lead
      Digital Meter (–) → BK (sensor BK) lead

• Measure   the input voltage with the engine stopped and
  with the connector joined.
• Turn the ignition switch on.
  Input Voltage
    Standard: DC 4.75  5.25 V

• Turn   the ignition switch off.
  If the reading is within the standard, check the output volt-
  age (see Throttle Position Sensor Output Voltage Inspec-
  tion(17-20)).
