GENERAL INFORMATION
This Trouble Code sets if the engine has been
running above 3000 RPM for more than 2
minutes and the Exhaust Temperature Sensor
Signal is above 4.90 Volts. Can be caused by
Damaged Wiring, a faulty Engine Temperature
Sensor or ECU / Connections.
This Trouble Code sets if the engine has been
running above 3000 RPM for more than 2
minutes and the Exhaust Temperature Sensor
Signal is below 0.06 Volts. Can be caused by
Damaged Wiring, a faulty Engine Temperature
Sensor or ECU / Connections.
This Trouble Code sets if the Exhaust
Temperature Sensor Signal changes Too Quickly
to be considered a Realistic Value. Can be
caused by Damaged Wiring, a faulty Exhaust
Temperature Sensor or ECU / Connections.
This Trouble Code sets if the Exhaust
Temperature 2 Signal is greater than 750C. Can
be caused by a Faulty Exhaust Temperature
Sensor/Connections or Lean Air/Fuel Ratio
causing high exhaust temperature.
This Trouble Code Sets if the if the Exhaust Temp
Sensor 2 Voltage is above 4.96V. Can be caused
by Damaged Wiring, a faulty Exhaust Temp
Sensor or ECU / Connections
This Trouble Code Sets if the if the Exhaust Temp
Sensor 2 Voltage is Below 0.06V. Can be caused
by Damaged Wiring, a faulty Exhaust Temp
Sensor or ECU / Connections
This Trouble Code sets if the Exhaust
Temperature Sensor Signal changes Too Quickly
to be considered a Realistic Value. Can be
caused by Damaged Wiring, a faulty Exhaust
Temperature Sensor or ECU / Connections.
This Trouble Code Sets when Exhaust
Temperature Sensor 2 signal is 250C greater than
Exhaust Temp Sensor 1 signal. The condition can
be caused by Damaged Wiring, faulty Exhaust
Temperature Sensor or ECU / Connections.
This Trouble Code indicates the Gear Switch
Signal Voltage is Outside an Acceptable Range.
Can be caused by Damaged Wiring or
Connectors in the Gear Switch Circuit, a
Damaged Switch, Resistor Pack or Faulty ECU
/Connections.
This Trouble Code indicates the Gear Switch
Signal Voltage is Above the Maximum Acceptable
Voltage. Can be caused by Damaged Wiring or
Connectors in the Gear Switch Circuit, a
Damaged Switch or Faulty ECU /Connections.
This Trouble Code indicates the Gear Switch
Signal Voltage is Below the Minimum Acceptable
Voltage. Can be caused by Damaged Wiring or
Connectors in the Gear Switch Circuit, a
Damaged Switch or Faulty ECU /Connections.
