2007 Honda Pilot P0430 OBD II Code Flashes Only When Fuel Tank Is Half Full
Hello, I own a 2007 Honda Pilot and am experiencing an intermittent Check Engine Light issue. The light turns off when the fuel tank is completely full and reactivates when the fuel level drops to about half. This behavior is accompanied by OBD II diagnostic code P043
If no other fault codes are present, there are no exhaust leaks near the rear oxygen sensor, and the sensor itself is functioning properly, then it's likely that the catalytic converter in Bank 2 is operating below efficiency as indicated by code P0430. For more detailed causes and solutions, refer to the trouble codes section of this forum.
