TROUBLE CODE SPN FMI
P-COD-
E
CONDITION
Throttle Position
Sensor 1 Voltage
High
51 3 P0123 This Trouble Code sets if the Throttle
Position Sensor Signal is above 4.61
Volts. Can be caused by Damaged Wiring,
a faulty Throttle Position Sensor or ECU /
Connections.
Throttle Position
Sensor 1 Voltage
Low
51 4 P0122 This Trouble Code sets if the Throttle
Position Sensor Signal is below 0.7 Volts.
Can be caused by Damaged Wiring, a
faulty Throttle Position Sensor or ECU /
Connections.
TPS Unrealistic
Transition
51 10 P0120 This Trouble Code sets when the Throttle
Position Sensor Signal changes too
rapidly to be correct. The condition can be
caused by intermittent connections
causing the TPS voltage to jump around
between readings. Check for damaged
connectors or wiring.
Vehicle Speed
Sensor Signal Fault
84 2 P0503 This Trouble Code Sets if the Vehicle
Speed Signal is intermittent or missing.
Can be caused by Damaged
Wiring/Connections or a Faulty/Loose
Vehicle Speed Sensor.
Intake Air Temp
Sensor Circuit
Voltage High
105 3 P0113 This Trouble Code sets if the Intake Air
Temperature Sensor Signal is above 4.9
Volts. Can be caused by Damaged Wiring,
a faulty Intake Air Temperature Sensor or
ECU / Connections.
Intake Air Temp
Sensor Circuit
Voltage Low
105 4 P0112 This Trouble Code sets if the Intake Air
Temperature Sensor Signal is below 0.19
Volts. Can be caused by Damaged Wiring,
a faulty Intake Air Temperature Sensor or
ECU / Connections.
IAT Sensor
Abnormal Rate of
Change
105 10 P0114 This Trouble Code sets if the Intake Air
Temperature Sensor Signal indicates an
Unrealistic Rate of Change. Can be
caused by Damaged Wiring, a faulty
Intake Air Temperature Sensor or ECU /
Connections.
Barometric Sensor
Circuit Voltage High
108 3 P2229 This Trouble Code Sets if the Barometric
Pressure Sensor Signal Circuit is Open or
Shorted to Battery Voltage. Can be
