Circuit DescriptionAn algorithm in the ECM calibration monitors engine speed as each injector fires. If a cylinder(s) has high or low contribution to engine speed, the fault will become active. The intention of the fault is to assist in troubleshooting performance complaints such as engine misfire and low power. Component LocationThe ECM mounting location varies, depending on the engine model, and may be mounted either on or off the engine. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting the Fault CodesThe Engine Control Module (ECM) detected a cylinder 6 misfire. Action Taken...

Circuit DescriptionThe aftertreatment diesel particulate filter temperature sensor module is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment diesel partculate filter temperature sensor module performs its own internal diagnostics and reports malfunctions back to the engine control module using the J1939 data link. The aftertreatment diesel particulate filter temperature sensor module is used to measure the aftertreatment diesel oxidation catalyst intake temperature, aftertreatment diesel particulate filter intake temperature, and aftertreatment diesel particulate filter outlet temperature. The temperature probes are permanently attached to the aftertreatment diesel particulate filter temperature sensor module and...
