Reaction:
Error code ECU 002659.15 is triggered when the ECU detects an EGR flow rate that is slightly higher than expected, even when the EGR valve is supposed to be closed. This unexpected flow can indicate a malfunction such as a sticking or leaking EGR valve.
Recommendations:
The vehicle’s control software may adjust EGR operations or engine parameters to compensate for the unintended flow, potentially affecting fuel efficiency and emissions control.
Note:
Regular maintenance of the EGR system, including checks for valve integrity and function, is crucial for maintaining emission standards and engine performance.
