How does the Honda exhaust gas recirculation system work?
P0401 Honda Description. The exhaust gas recirculation (EGR system reduces oxides of nitrogen (NOx). NOx is generated by high combustion temperatures. The EGR system lowers peak combustion temperature by recirculating inactive exhaust gas into the air/fuel mixture, thus reducing NOx emissions.
What causes an exhaust gas leak in a Honda?
P0401 HONDA Possible Causes Exhaust Gas Recirculation Valve harness is open or shorted Exhaust Gas Recirculation Valve circuit poor electrical connection Faulty Exhaust Gas Recirculation Valve Exhaust Gas Recirculation Valve clogged Exhaust gas leaks
What are the symptoms of a bad exhaust gas recirculation?

What to do if your Honda Accord has DTC p0401?
If DTC P0401 or P1491 is stored, or if the engine hesitates or surges, clean the EGR port, install an EGR pipe kit, and clear the code. The problem is also common in most 1998-2001 Honda Accord.

What causes an exhaust gas leak on a Honda?
P1491 Honda Possible Causes. Faulty Exhaust Gas Recirculation (EGR) Valve. Exhaust Gas Recirculation Valve harness is open or shorted. Exhaust Gas Recirculation Valve circuit poor electrical connection. Exhaust Gas Recirculation Valve clogged. Exhaust gas leaks.
Where is the exhaust gas recirculation valve located?
The exhaust gas recirculation valve is a component commonly found on many road going vehicles. It is a part of the vehicle’s exhaust gas recirculation (EGR) system, an emissions system that is designed to recirculate exhaust gases back into the vehicle’s intake in order to reduce cylinder temperatures and NOx emissions.
