SPN = SUSPECT PARAMETER NUMBER / FMI = FAILURE MODE INDICATOR
TROUBLE CODE SPN FMI
P-COD-
E
CONDITION
Fuel Rail Pressure
Sensor Voltage
Low
157 4 P0192 This Trouble Code Sets if the Fuel
Pressure Sensor Circuit is below 0.1V.
Can be caused by Damaged Wiring, a
faulty Fuel Pressure Sensor or ECU /
Connections.
Fuel Rail Pressure
Below Power Limit
157 18 P0196 This Trouble Code Sets if the Fuel
Pressure drops below 3Bar (43.5PSI) for
10 seconds. Can be caused by a faulty
Pump Flange Assembly (PFA).
Battery Voltage
High
158 3 P1567 This Trouble Code Sets if the if the Battery
Voltage is above 15.0V. Can be caused by
Damaged Wiring, a faulty Battery or ECU /
Connections.
Battery Voltage
Low
158 4 P1566 This Trouble Code Sets if the if the Battery
Voltage is below 10.0V. Can be caused by
Damaged Wiring, a faulty Battery or ECU /
Connections.
Exhaust
Over-Temperature
Shutdown
173 0 P1517 This Trouble Code Sets if the engine was
shut down due to High Exhaust
Temperature. Can be caused by a Faulty
Exhaust Temperature
Sensor/Connections or Lean Air/Fuel
Ratio causing high exhaust temperature.
Exhaust Temp
Sensor Signal High
173 3 P0546 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.
Exhaust Temp
Sensor Signal Low
173 4 P0545 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.
Exhaust Temp
Sensor Unrealistic
Transition
173 10 P1546 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.
