DTC 1112-RPM Above Spark Rev Limit Level
• Hardware: Spark Rev Limit- Crankshaft Position Sensor
• Enabling Conditions: Engine Running
• Set Conditions: Engine speed greater than the Spark Rev Limit speed (4200 min
-1
(rpm)) for longer than 0.5
seconds
• Corrective Action(s): Illuminate MIL
• Non-emissions related fault
• Possible Causes: Engine over speed condition, faulty CKP sensor or input
The fault of DTC 219 will set anytime the engine RPM exceeds 3900 min
-1
(rpm) for longer than 1 second. This
fault is designed to help prevent engine or equipment damage. The throttle will be lowered in order to govern the
engine to the speed set in the diagnostic calibration.
The fault of DTC 1111 will set anytime the engine RPM exceeds the limit set in the diagnostic calibration for the
latch time or more. This speed overrides any higher max governor speeds programmed by the user. This fault is
designed to help prevent engine or equipment damage and will disable fuel injectors or gaseous fuel actuator to
reduce engine speed. The throttle will also be lowered in order to govern the engine to the speed set in the diagnostic
calibration for Max Gov Override.
The fault of DTC 1112 will set anytime the engine RPM exceeds the limit set in the diagnostic calibration for the
latch time or more. This speed overrides any higher max governor speeds programmed by the user. This fault is
designed to help prevent engine or equipment damage and will disable the ignition coils to reduce engine speed. In
addition, the throttle will be lowered in order to govern the engine to the speed set in the diagnostic calibration for Max
Gov Override and the fuel injectors or gaseous fuel control actuator will be disabled to reduce the engine speed below
the speed set in the diagnostic calibration for Fuel Rev Limit.
DTC 219-RPM Higher Than Max Allowed Governed Speed
Diagnostic Aids
NOTE
• If any other DTCs are present, diagnose those first.
• Ensure that no programmed governor speeds exceed the limit set in the diagnostic calibration for Max Gov
Override Speed
• Check mechanical operation of the throttle
• Check the engine intake for large air leaks downstream of the throttle body
