I am sorry, the monitor does not allow for clearing of codes. This can only be done with the dealer service tool CAT ET.

If the code is not active, it will not cause a problem. EVENT codes (preceded by the letter E) will automatically erase themselves.

If the machine is still having trouble, the problem has not been fixed. Check the harness for damage and/or replace the sensor.
