Neutral Switch (M/T)

^ These are "ON/OFF" switches located on the transmission.
^ The neutral switch signals the ECU that the gear selector is either in neutral or any other position.
^ The clutch switch is operated by the clutch pedal inside the vehicle and informs the ECU that the clutch is either engaged or disengaged.
^ These inputs are used by the ECU in calculations for these outputs:
^ Fuel injection quantity
^ Idle speed control valve
^ Purge control solenoid valve
^ Igniter (timing control)
