Description of Flash Code 11

Flash Code 11 indicates that the Variable Speed Governor (VSG) input to the ECM has dropped below 5% (normally < 0.25 volts) of the sensor supply voltage. This diagnostic condition is typically:‪

  • Open sensor signal circuit (No VSG throttle control installed.)
  • Open sensor +5 volt supply circuit
  • Sensor signal is shorted to the sensor return circuit or to ground
  • Sensor +5 volt supply is shorted to sensor return circuit or to ground (This condition will result in numerous sensor codes.)
