P0420

The P0420 code indicates that the catalytic converter's efficiency is below the threshold, specifically on a Ford F-150 from the 12th Generation (2009-2014).

The P0420 code indicates that the catalytic converter's efficiency is below the threshold set by the manufacturer for a Ford F-150 from the 12th generation (2009-2014).

The P0420 code indicates that the catalytic converter system efficiency is below the threshold for a Ford F-150 12th Generation (2009-2014). This can lead to poor emissions performance and may trigger the check engine light.

The P0420 code indicates a "Catalytic Converter Efficiency Below Threshold" for a Ford F-150, 12th Generation (2009-2014). This suggests that the catalytic converter may be underperforming, potentially due to a faulty converter, exhaust leaks, or issues with the oxygen sensors.

The P0420 code on your 2009-2014 Ford F-150 indicates that the engine control module (ECM) has detected a problem with the catalytic converter's efficiency, suggesting it may not be functioning optimally.

The P0420 code indicates that the catalytic converter is not functioning efficiently in a 12th Generation Ford F-150 (2009-2014).

The P0420 code on a 12th Generation Ford F-150 (2009-2014) indicates that the catalytic converter's efficiency is below the threshold, suggesting issues with the catalytic converter or the oxygen sensors.

The P0420 code indicates that the catalytic converter's efficiency is below the required threshold on a 12th Generation Ford F-150 (2009-2014).
