Reason
Effect (only when fault code is active)
111
629
12
Engine control module critical internal failure -
Bad intelligent device or component. Error
internal to the ECM related to memory hardware
failures or internal ECM voltage supply circuits.
Possible no noticeable performance effects,
engine dying, or hard starting.
115
612
2
Engine magnetic crankshaft speed/position lost
both of two signals - Data erratic, intermittent, or
incorrect. The ECM has detected the primary
and backup speed sensor signals are connected
backwards.
The engine will shut down or will not start.
122
102
3
Intake manifold 1 pressure sensor circuit -
Voltage above normal, or shorted to high source.
High signal voltage detected at the intake
manifold pressure circuit.
Engine power derate.
123
102
4
Intake manifold 1 pressure sensor circuit -
Voltage below normal, or shorted to low Source.
Low signal voltage or open circuit detected at the
intake manifold pressure circuit.
Engine power derate.
124
102
16
Intake manifold 1 pressure - Data valid but above
normal operational range - Moderately severe
level. Intake manifold pressure is above the
maximum operating limit.
Engine power derate.
125
102
18
Intake Manifold 1 Pressure - Data valid but
below normal operating range - Moderately
severe level. Intake manifold pressure is below
the minimum operating limit.
Engine power derate.
131
91
3
Accelerator pedal or lever position sensor 1
circuit - Voltage above normal, or shorted to high
source. High voltage detected at accelerator
pedal position number 1 circuit.
The engine will operate in limp home mode.
132
91
4
Accelerator pedal or lever position sensor 1
circuit - Voltage below normal, or shorted to low
source. Low voltage detected at accelerator
pedal position number 1 signal circuit.
The engine will operate in limp home mode.
133
974
3
Remote accelerator pedal or lever position
sensor 1 circuit - Voltage above normal, or
shorted to high source. High voltage detected at
remote accelerator pedal position signal circuit.
Remote accelerator will not operate.
134
974
4
Remote accelerator pedal or lever position
sensor 1 circuit - Voltage below normal, or
shorted to low source. Low voltage detected at
remote accelerator pedal position signal circuit.
Remote accelerator will not operate.
143
100
18
Engine oil rifle pressure - Data valid but below
normal operational range - Moderately severe
level. Engine oil pressure signal indicates engine
oil pressure is below the engine protection
warning limit.
Engine power derate.
