Description:

This error code, ECU 000105.00, occurs when the mixed air temperature in the exhaust gas recirculation (EGR) system significantly exceeds expected levels. This condition suggests an abnormal increase in the intake manifold air temperature, potentially due to EGR system malfunctions, such as clogging or operational faults.

Reaction:

An excessively high mixed air temperature can trigger safety protocols to limit engine power to prevent damage from overheating.

Recommendations:

• Inspect EGR System: Check for blockages or mechanical failures within the EGR system that could be causing excessive heat buildup.
• Monitor Temperature Sensors: Verify that temperature sensors in the intake manifold are functioning correctly and providing accurate readings.
• Clear EGR Pathways: Clean or replace any components of the EGR system that are contributing to restricted airflow or heat dissipation issues.
• System Reset and Error Code Clearance: After addressing the issue, reset the engine control unit and clear any associated error codes to ensure system integrity.

Note:

Regular maintenance of the EGR system is crucial to preventing overheating issues and ensuring optimal engine performance and emissions control.
