DESCRIPTION
Throttle Position Sensor Unrealistic Transition P0120
1
TPS signal changes too rapidly to be correct. Can be caused by faulty
connections or a faulty TPS.
Throttle Position Sensor Voltage High P0123
TPS signal is above 4.39 Vdc. Can be caused by a faulty wire
connection or faulty TPS.
Throttle Position Sensor Voltage Low P0122
TPS signal is below 0.7 Vdc. Can be caused by a faulty wire
connection or faulty TPS.
Engine Coolant Temperature Sensor Voltage High P0118
2
Sensor signal is above 4.8 Vdc. Can be caused by a faulty wire
connection or faulty temperature sensor.
Engine Coolant Temperature Sensor Voltage Low P0117
Sensor signal is below 0.1 Vdc. Can be caused by a faulty wire
connection or faulty temperature sensor.
Intake Air Temperature Circuit Voltage High P0113
3
Sensor signal is above 4.9 Vdc. Can be caused by a faulty wire
connection or faulty TBAP.
Intake Air Temperature Circuit Voltage Low P0112
Sensor signal is below 0.19 Vdc. Can be caused by a faulty wire
connection or faulty TBAP.
Barometric Pressure Sensor Voltage High P0108
4
Sensor signal is above 3.23 Vdc. Can be caused by a faulty wire
connection or faulty TBAP.
Barometric Pressure Sensor Voltage Low P0107
Sensor signal is below 1.25 Vdc. Can be caused by a faulty wire
connection of faulty TBAP.
Exhaust Temperature Sensor Circuit Voltage High P0546
5
Sensor signal is above 4.9 Vdc for at least 2 minutes and the engine
has been running at or above 3000 RPM.
Exhaust Temperature Sensor Circuit Voltage Low P0545
Sensor signal is below 0.06 Vdc for at least 2 minutes and the engine
has been running at or above 3000 RPM.
Detonation Sensor Circuit Voltage High P0328
6
Engine speed is above 6000 RPM and the sensor signal is above 4.3
Vdc for at least 2 seconds.
Detonation Sensor Circuit Voltage Low P0327
Engine speed is above 6000 RPM and the sensor signal is below 1.23
Vdc for at least 2 seconds.
Exhaust Valve Solenoid Circuit Malfunction P1477 8
Solenoid control circuit is OPEN. Can be caused by faulty wiring,
solenoid, or ECU.
MAG Part Load Injector Circuit Open P0261
7
OPEN circuit or short to ground. Can be caused by faulty wiring,
injector, stator or ECU.
MAG Full Load Injector Circuit Open P1261
PTO Part Load Injector Circuit Open P0264
PTO Full Load Injector Circuit Open P1264
Fuel Injector Voltage Too High P2148
Engine is running, but the injector voltage is above the acceptable
limit. Can be caused by faulty wiring, ECU or stator.
Fuel Injector Voltage Too Low P2147
Engine is running, but the injector voltage is below the acceptable
limit. Can be caused by faulty wiring, ECU or stator.
Vehicle Speed Sensor No Signal P0500 Steady LED
Sensor has given a speed that is not possible with given engine
conditions. Can be caused by a faulty sensor, wiring or ECU.
MAG Ignition Coil Circuit Malfunction P0351
9
Failure within the primary circuit. Can be caused by faulty wiring,
ignition coil, or ECU.
PTO Ignition Coil Circuit Malfunction P0352
5 Tooth CPS Signal Missing P0335 10
Engine is running, but there is no signal from the 5 tooth CPS. Can
be caused by a faulty stator, wiring or ECU.
