Reason
Effect (only when fault code is active)
196
111
4
Coolant level sensor 1 circuit - Voltage below
normal, or shorted to low source. Low signal
voltage detected at engine coolant level circuit.
None on performance.
197
111
18
Coolant level - Data valid but below normal
operational range - Moderately severe level.
Low coolant level has been detected.
Engine power derate.
221
108
3
Barometric pressure sensor circuit - Voltage
above normal, or shorted to high source. High
signal voltage detected at barometric pressure
circuit.
Engine power derate.
222
108
4
Barometric pressure sensor circuit - Voltage
below normal, or shorted to low source. Low
signal voltage detected at barometric pressure
circuit.
Engine power derate.
227
3510
3
Sensor supply 2 circuit - Voltage above normal,
or shor ted to high source. High voltage
detected at sensor supply number 2 circuit.
Engine power derate.
234
190
0
Engine crankshaft speed/position - Data valid
but above normal operational range - Most
severe level. Engine speed signal indicates
engine speed above engine protection limit.
Engine power derate.
238
3511
4
Sensor supply 3 circuit - Voltage below normal,
or shorted to low source. Low voltage detected
on the +5 volt sensor supply circuit to the
engine speed sensor.
Engine may run rough, may stop running, may
not start, or may be difficult to start.
239
3511
3
Sensor supply 3 circuit - Voltage above normal
or shor ted to high source. High voltage
detected on the 5 volt sensor supply circuit to
the engine speed sensor.
Engine may run rough, may stop running, may
not start, or may be difficult to start.
241
84
2
Wheel-based vehicle speed - Data erratic,
intermittent, or incorrect. The ECM lost the
vehicle speed signal or is reading an erratic
value.
Engine speed limited to ,maximum engine
speed without VSS parameter value. Cruise
control, gear-down protection, and road speed
governor will not work.
245
647
4
Fan control circuit - Voltage below normal, or
shorted to low source. Low signal voltage
detected at the fan control circuit when
commanded on.
The fan may stay on continuously or not run at
all.
249
171
3
Ambient air temperature sensor 1 circuit -
Voltage above normal or shorted to high
source. High signal voltage detected at ambient
air temperature circuit.
Possible reduced engine performance.
256
171
4
Ambient air temperature sensor 1 circuit -
Voltage below normal or shorted to low source.
L o w vo l t a g e d e t e c t e d a t a m b i e n t a i r
temperature circuit.
Possible reduced engine performance.
271
1347
4
Fuel pump pressurizing assembly 1 circuit -
Voltage below normal, or shorted to low source.
Low signal voltage detected at the fuel pump
actuator circuit.
Engine power derate.
