Cummins ISB4.5 CM2150 Fault Code: 2347 PID: SPN: 2347 FMI: 0 Turbocharger Compressor Outlet Temperature (Calculated) – Data Valid but Above Normal Operating Range – Least Severe Level.
Geplaatst door Diezel Solutions op
Circuit DescriptionThe turbocharger compressor outlet air temperature is calculated by the ECM. Turbocharger compressor outlet air temperature is derived by the ECM, based on engine operating conditions such as turbocharger compressor inlet air temperature, barometric pressure, turbocharger speed, engine speed, intake manifold air temperature, and intake manifold pressure. Component LocationThere is not a physical turbocharger compressor outlet temperature sensor in the system. The turbocharger compressor outlet air temperature is a calculation of temperature of the air after it is compressed by the turbocharger compressor, but before exhaust gas recirculation (EGR) is mixed into the system and before it enters the...
Cummins ISB4.5 CM2150 Fault Code: 2351 PID: SID 146 SPN: 2791 FMI: 4 EGR Valve Control Circuit – Voltage Below Normal or Shorted to Low Source.
Geplaatst door Diezel Solutions op
Circuit DescriptionThe engine control module (ECM) controls the EGR valve, opening and closing it based on various operating conditions. The EGR valve is opened and closed by a DC motor that receives voltage from the ECM on the EGR valve motor signal (+) and (-) circuits. To open the valve, the motor receives voltage on the EGR valve motor signal (+) circuit. To close the valve, the motor receives voltage on the EGR valve motor signal (-) circuit. Component LocationThe EGR valve is located on the exhaust side of the engine and is attached to the EGR cooler, which is...

Cummins ISB4.5 CM2150 Fault Code: 2363 PID: SID 29 SPN: 1073 FMI: 4 Engine Brake Actuator Driver Output 2 Circuit – Voltage Below Normal or Shorted to Low Source.
Geplaatst door Diezel Solutions op
Circuit DescriptionThe engine control module (ECM) controls engine brakes on cylinders 4, 5, and 6 by sending a signal on the engine brake solenoid number 2 signal circuit. A 2-pin Weather Pack™ connector is located near the number 3 injector pass-through connector at the back of the engine. There is a jumper harness from this connector to the engine brake pass-through connectors on the rocker lever housing. Component LocationThe engine brake solenoids are located under the valve cover. The engine brake solenoids are controlled through the engine harness by the ECM. Conditions for Running the DiagnosticsThis diagnostic runs when the...
