Description:

This diagnostic trouble code indicates a data transfer problem between the Engine Control Unit (ECU) and the intake air sensor. The ECU is unable to receive CAN Bus messages from the intake air sensor, which can impact the accurate monitoring and control of engine air intake.

Reaction:

The ECU may limit or adjust the operation of the engine to manage the inability to receive intake air sensor data, which could result in reduced engine performance and efficiency.

Recommendations:

• Inspect CAN Bus Wiring and Connections: Check for damaged, frayed, or loose wiring and connectors associated with the CAN Bus between the ECU and the intake air sensor. Repair or replace as necessary.
• Test CAN Bus Communication: Use diagnostic tools to test the CAN Bus communication between the ECU and the intake air sensor. Ensure that there are no interruptions or data transfer issues.
• Check for Loose Connections: Verify that all connections between the ECU and the intake air sensor are secure and free of corrosion.
• Verify Intake Air Sensor Function: Ensure that the intake air sensor is functioning correctly and is able to send data.
• Reset ECU and Monitor System: After resolving the issue, reset the ECU to clear the fault code and monitor the system to ensure normal operation.

Note:

Maintaining proper communication between the ECU and the intake air sensor is crucial for accurate engine air intake monitoring and control. Regular inspections and timely maintenance can help prevent communication-related issues.
