Reason
Effect (only when fault code is active)
731
723
7
Engine speed / position camshaft and
crankshaft misalignment - Mechanical system
not responding properly or out of adjustment.
Engine position signal from the crankshaft
position sensor and camshaft position sensor
do not match.
Engine power derate.
755
157
7
Injector metering rail 1 pressure - Mechanical
system not responding or out of adjustment.
The ecm has detected a difference in the 2 fuel
rail pressure signals.
Possible reduced engine performance.
778
723
2
Engine camshaft speed / position sensor - Data
erratic, intermittent, or incorrect. The ECM has
detected an error in the camshaft position
sensor signal.
Possible reduced engine performance.
784
1590
2
Adaptive cruise control mode - Data erratic,
intermittent, or incorrect.
Loss of communication with adaptive cruise
control.
Adaptive cruise control will not operate.
Standard cruise control may not operate.
1117
627
2
Power supply lost with ignition on - Data erratic,
intermittent, or incorrect. Supply voltage to the
ECM fell below 6.2 volts momentarily, or the
ECM was not allowed to power down correctly
(retain battery voltage for 30 seconds after key
OFF).
Possible no noticeable performance.
1139
651
7
Injector solenoid driver cylinder 1 - Mechanical
system not responding or out of adjustment.
The ECM has detected an error with the
injection timing or quantity.
Possible reduced engine performance.
1141
652
7
Injector solenoid driver cylinder 2 - Mechanical
system not responding or out of adjustment.
The ECM has detected an error with the
injection timing or quantity.
Possible reduced engine performance.
1142
653
7
Injector solenoid driver cylinder 3 - Mechanical
system not responding or out of adjustment.
The ECM has detected an error with the
injection timing or quantity.
Possible reduced engine performance.
1143
654
7
Injector solenoid driver cylinder 4 - Mechanical
system not responding or out of adjustment.
The ECM has detected an error with the
injection timing or quantity.
Possible reduced engine performance.
1144
655
7
Injector solenoid driver cylinder 5 - Mechanical
system not responding or out of adjustment.
The ECM has detected an error with the
injection timing or quantity.
Possible reduced engine performance.
1145
656
7
Injector solenoid driver cylinder 6 - Mechanical
system not responding or out of adjustment.
The ECM has detected an error with the
injection timing or quantity.
Possible reduced engine performance.
1228
27
2
Egr valve position - Data erratic, intermittent, or
Incorrect. The EGR valve is unable to meet
commanded position.
Possible reduced engine performance.
