Reason
Effect (only when fault code is active)
144
110
3
Engine coolant temperature 1 sensor circuit -
Voltage above normal, or shorted to high
source. High signal voltage or open circuit
detected at engine coolant temperature circuit.
Fan will stay ON if controlled by ECM.
145
110
4
Engine coolant temperature 1 sensor circuit -
Voltage below normal, or shorted to low source.
Low signal voltage detected at engine coolant
temperature circuit.
Fan will stay ON if controlled by ECM.
146
110
16
Engine coolant temperature - Data valid but
above normal operational range - Moderately
severe level. Engine coolant temperature is
above engine protection warning limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red stop lamp starts flashing.
151
110
0
Engine coolant temperature - Data valid but
above normal operational range - Most severe
level. Engine coolant temperature signal
indicates engine coolant temperature above
engine protection critical limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red stop lamp starts flashing.
153
105
3
Intake manifold 1 temperature sensor circuit -
Voltage above normal, or shorted to high
source. High signal voltage detected at intake
manifold air temperature circuit.
Fan will stay ON if controlled by ECM.
154
105
4
Intake manifold 1 temperature sensor circuit -
Voltage below normal, or shorted to low source.
Low signal voltage detected at intake manifold
air temperature circuit.
Fan will stay ON if controlled by ECM.
155
105
0
Intake manifold 1 temperature - Data valid but
above normal operational range - Most severe
level. Intake manifold air temperature signal
indicates intake manifold air temperature above
engine protection critical limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If the
engine protection shutdown feature is enabled,
the engine will shut down 30 seconds after the
red stop lamp starts flashing.
175
3464
3
Electronic throttle control actuator driver circuit -
Voltage above normal, or shorted to high
source. A short circuit to battery or open circuit
has been detected in the engine intake air
throttle actuator signal circuit.
Possible reduced engine performance.
176
3464
4
Electronic throttle control actuator driver circuit -
Voltage below normal, or shorted to low source.
A short circuit to ground has been detected in
the engine intake air throttle actuator signal
circuit.
Possible reduced engine performance.
177
3464
7
Electronic throttle control actuator - Mechanical
system not responding or out of adjustment.
The engine intake air throttle actuator has failed
the auto zero span check.
Possible reduced engine performance.
187
3510
4
Sensor supply 2 circuit - Voltage below normal,
or shorted to low source. Low voltage detected
at the sensor supply number 2 circuit.
Engine power derate.
195
111
3
Coolant level sensor 1 circuit - Voltage above
normal, or shorted to high source. High signal
voltage detected at engine coolant level circuit.
None on performance.
