What is the EGR system on a Honda Accord?
The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the Accord’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.
What to do if your EGR valve is insufficient?
Most folks see P0401 Insufficient EGR flow, look up the price of an EGR valve, see how cheap it is and just throw a new one on. That can be a mistake. That’s because the EGR valve is not always going to be the culprit.
What are the three parts of the EGR system?
There are three main parts of the Accord’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401 is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Honda Accord or not).
What to do if your Honda Accord p0401 has insufficient flow?
Here are some of the most common fixes to help clear the P0401: Check the EGR Tube- It’s a good idea to check the tube going to the EGR because it’s often the cause of P0401, easy to do, fast, and replacing it is very afHondaable. If it’s cracked, you’ll need to get a new one.
Can you accumulate carbon in an EGR valve?
Carbon can’t accumulate in an EGR valve in a short time, unless there is something horribly wrong with the engine, which you would know, because the car would be nearly impossible to drive. You need a new mechanic. I agree with mcparadise.
What happens if the EGR valve is stuck?
If it’s stuck OPEN, then your car won’t idle or accelerate properly. Sometimes EGR valves are fed by an external tube coming from the exhaust manifold. These tubes can plug up and throw a “EGR low flow” code. Remove and clean, or replace, the plugged up tube that FEEDS the EGR valve.
When do you need an EGR system code?
Getting an EGR system code does not necessariy mean the EGR valve itself is bad. Once a code is obtained this is when the manual and the diagnostic procedure is used to determine exactly where the problem lies in the EGR system. as i said. CODE PLEASE!
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 does the p1491 Honda engine code mean?
P1491 HONDA Meaning 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 does DTC p0401 mean on a Honda Accord?
If this happens, the vehicle may hesitate or surge during light acceleration, and the MIL (malfunction indicator lamp) may come on with DTC P0401 (EGR insufficient flow) or P1491 (EGR valve insufficient lift). 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.

What does p0401 stand for in Honda Accord?
P0401 is a common OBDII trouble code that’ll pop up in the Honda Accord. It has to do with the emissions system and stands for: P0401: EGR → Insufficient Flow The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output.
Is the Check Engine light on in my Honda Accord?
This small yellow light (labeled “maintenance indicator”) is not the “check engine” light (1991 Honda Accord) How Long Can You Drive With Your Check Engine Light On? Is the car running normally?
Here are some of the most common fixes to help clear the P0401: Check the EGR Tube- It’s a good idea to check the tube going to the EGR because it’s often the cause of P0401, easy to do, fast, and replacing it is very afHondaable. If it’s cracked, you’ll need to get a new one.
What is the code for the Honda check engine light?
A long flash (or approximately one second) equals 10. A short code (or approximately half a second) equals one. For example, two long flashes followed by two short flashes will equal to the code 22. Any subsequent codes will follow in 2.5 second intervals.
What kind of error code does Honda Accord have?
This repair also applies to 2002, 2003, 2004, 2005, 2006, and 2007 Honda Accords, as well as other Honda’s using the i-VTEC engine (Honda Element, Honda Civic, Honda CRV), with perhaps some variations depending on the vehicle. This issue can also produce a P2646 error code.
