Description:

Error code ECU 000107.00 occurs when the ECU detects that the air cleaner restriction switch (B02) is closed, signifying a restriction in the air filter system. This typically happens due to a clogged or excessively dirty engine air filter or a problem in the circuitry of the air cleaner restriction switch. For Stage II engines, this specific signal is indicative of significant airflow obstruction, which could impede engine performance.

Reaction:

The engine may experience reduced power and efficiency. Increased fuel consumption and elevated exhaust emissions are common as the engine compensates for reduced air intake.

Recommendations:

• Inspect and Replace Air Filter: Check the engine air filter for dirt accumulation and replace it if necessary to restore proper airflow.
• Check Air Cleaner Restriction Switch (B02): Ensure that the switch and associated wiring are intact and functioning correctly. Repair or replace faulty components.
• Reset ECU and Clear Codes: After the air filter and any circuit issues have been addressed, reset the ECU to clear the fault code and recalibrate the system’s air intake readings.

Note:

Regular inspection and maintenance of the air filtration system are crucial to prevent this type of issue and ensure optimal engine performance.
