Error code ECU 002791.14 is generated when the EGR valve is forced to shut down due to a significant fault or operational hazard. This drastic measure is taken to protect the engine and maintain compliance with emission standards under critical fault conditions.

This error code indicates that the EGR valve is unable to achieve the desired position, suggesting that it is out of calibration. This may result from wear, buildup, or electronic issues affecting the valve’s operation.

READ MORE

This diagnostic code, ECU 002791.07, is set when there is a discrepancy between the desired and actual positions of the EGR valve, indicating that the valve is not responding correctly or is out of adjustment during its learning process. This may be due to mechanical sticking, actuator failure, or feedback sensor issues.

Error code ECU 002791.06 arises when the current to the EGR valve actuator is too high, suggesting a short to ground in the actuator’s electrical circuit.

READ MORE

This diagnostic trouble code indicates that the circuit current for the EGR valve actuator is too low, pointing to an open circuit within the system.

Error code ECU 002791.04 is set when the EGR valve position signal falls below the minimum acceptable range, suggesting a potential fault in the valve’s position sensing mechanism or related circuitry.

READ MORE

This diagnostic code, ECU 002791.03, is set when the EGR valve position signal exceeds the highest permissible limit, indicating a potential electrical or mechanical fault in the EGR valve system.

Error code ECU 002791.02 indicates that the EGR valve is not able to achieve the desired position, likely due to being stuck open or closed. This malfunction can significantly affect engine performance by disrupting the flow of exhaust gases, necessary for reducing NOx emissions.

This error code, ECU 002790.16, is triggered when the turbocharger compressor outlet temperature exceeds the moderate threshold above the specified limit. This condition can indicate a potential issue with the turbocharger system, such as a clog in the intercooler, inefficient cooling, or excessive engine load.

Error code ECU 002659.18 is set when the NOx-based EGR flow correction factor falls to a moderately low level, indicating that the EGR flow venturi may require cleaning due to accumulation that affects accurate flow measurement and subsequent NOx control.

READ MORE

This error code indicates that the ECU does not detect sufficient EGR flow when the EGR valve is open, suggesting potential issues such as clogging, restricted flow, or a malfunctioning valve.
