Typical example
(13) Coolant temperature sensor Engine Monitoring
The electronic control system includes Engine Monitoring. The system monitors engine oil pressure, coolant temperature, inlet manifold air temperature and coolant level. All truck engines are shipped from the factory with the following sensors: oil pressure sensor, coolant temperature sensor and inlet manifold air temperature. The OEM is responsible for providing and installing the coolant level sensor. The coolant level sensor is the only sensor that can be individually selected for Engine Monitoring. The ECM Customer Programmable Parameter enables the coolant level sensor. The default factory setting is "NO". The ECM Customer Programmable Parameters have four levels that are for Engine Monitoring:
OFF
Warning (Factory Default)
Derate
ShutdownEngine Monitoring Off Mode
The ECM will ignore the oil pressure sensor and the coolant level sensor. Coolant Temperature is still used for Cold Mode. Inlet Manifold Air Temperature is used for operation in cold air regardless of the engine monitoring mode."Engine Monitoring Warning Mode"
Warning mode uses the following sensors: Oil Pressure, Coolant Temperature, Inlet Manifold Temperature and Optional Coolant Level Sensor. Table 1 indicates the diagnostic codes that are available. The table also shows the effect on engine performance when the diagnostic code is active. When a diagnostic code is active, the Check Engine Lamp will flash and the Warning Lamp will come on.

PID-FMI Description of the Fault Code Warning Lamp Derate
100-01 Low Oil Pressure Warning SOLID NONE
100-11 Very Low Oil Pressure Warning SOLID NONE
105-00 "High Inlet Manifold Air Temperature Warning" SOLID NONE
105-11 "Very High Inlet Manifold Air Temperature Warning" SOLID NONE
110-00 "High Coolant Temperature Warning" SOLID NONE
110-11 "Very High Coolant Temperature" SOLID NONE
111-01 "Low Coolant Level Warning" SOLID NONE
111-11 "Very Low Coolant Level" SOLID NONE Engine Monitoring Derate and Shutdown Modes
Derate mode and Shutdown mode allow the ECM to alter engine performance in order to avoid damage to the engine. The engine should return to normal conditions once the problem is corrected. When the engine is derated, the Check Engine Lamp and the Warning Lamp will flash. Refer to Table 2. In the Derate column, MPH indicates that the vehicle speed is derated. The maximum derate is 45 mph. HP indicates that the engine horsepower is limited. The maximum derate is 160 hp. RPM indicates that the engine speed is limited. The maximum derate is 1350 rpm. For the operating conditions that cause these codes, refer to the appropriate section for the sensor.

Table 3 indicates the active diagnostic codes that are capable of shutting down the engine when the ECM is programmed to Shutdown. The “Time To Shutdown” column indicates the amount of time of engine operation after a diagnostic code is activated. The engine must have been running for at least thirty seconds in order to activate this mode. The “Start/Restart Time” column indicates the amount of time for engine operation after start-up if the condition still exists. The “Start/Restart Time” follows a shutdown that is caused by the “Engine Monitoring” function. A "NO" indicates that the code will not cause a shutdown of the engine.
