Idle and full throttle switches, checkingWork sequence
- Unplug connector for idle and full throttle switches at throttle body
Voltage supply, checking
- Connect voltmeter between terminal 2 of connector C and ground
- Switch ON ignition
^ Specification: approx 12 V
- Switch OFF ignition
If NOT OK
- Check for open circuit in wiring and repair as necessary, see
current flow diagram
Idle switch, checking
- Connect ohmmeter between terminals 1 and 2
^ Specification: approx. 0 ohm
- Actuate switch with throttle lever
^ Specification: infinite ohm
If NO
- Adjust idle switch
- repeat measuremenT
If still NO
- Replace idle switch and adjustIf OK

Full throttle switch, checking
Work sequence
- Connect ohmmeter between contacts 2 and 3
^ Specification: infinite ohm
- Actuate switch with throttle lever
^ Specification: 0 ohm
If NO
- Adjust full throttle switch
- Recheck with ohmmeter
If still NO
- Replace full throttle switch
If OK
- Check wiring between connector C and control unit connector A as follows
- Remove control unit cover located in footwell on passenger side of vehicle
- Unplug control unit connector
- Use ohmmeter to check continuity between terminals of connector C and control unit connector A:
^ Connector C terminal (1) and control unit connector A terminal (20)
^ Connector C terminal (3) and control unit connector A terminal (26)
^ Each specification: approx. 0 ohm
If NO
- Check for open circuit in wiring between connectors A and C according to current flow diagram
If specs. OK and system NOT OK
- Replace control unit
