Description:

Error code ECU 000108.02 indicates that the ECU is receiving invalid pressure information from the barometric air pressure sensor. This suggests a fault within the sensor itself, which is integrated within the engine control unit. Faulty readings from this sensor can affect engine performance since accurate barometric pressure data is critical for adjusting the fuel injection and air intake systems.

Reaction:

The engine management system may not correctly adjust to changing atmospheric conditions, potentially leading to inefficiencies in fuel usage, reduced engine power, and increased emissions.

Recommendations:

• Inspect the Sensor: Check the barometric air pressure sensor for damage or disconnections.
• Test Sensor Functionality: Perform diagnostic tests to verify the accuracy of the sensor’s readings.
• Replace Faulty Sensor: If the sensor is found to be defective, replace it to ensure accurate barometric pressure measurements.
• ECU Check and Reset: After replacement, check the ECU for any related error codes and reset it to ensure it accurately processes the new sensor’s data.

Note:

Regular calibration and maintenance of the sensor are essential to prevent such issues, particularly in environments with fluctuating atmospheric conditions.
