Car Forum / Honda Cars / September 2006PO401 EGR flow fault
What's the best way and or cheapest way to fix my 1997 Honda Accord EX v6 PO401 EGR flow fault? Can the EGR valve be cleaned instead of replaced or could a vacuum leak cause the fault? > What's the best way and or cheapest way to fix my 1997 Honda Accord EX v6 > PO401 EGR flow fault?

My '98 Odyssey (VTEC 4) is showing the same code. | Can the EGR valve be cleaned instead of replaced or | could a vacuum leak cause the fault? www.autozone.com/servlet/UiBroker?UseCase=RG001&UserAction=beginRepairGuide > www.autozone.com/servlet/UiBroker?UseCase=RG001&UserAction=beginRepairGuide Good idea, but no help if your Honda was made after 1995. Most VTEC Hondas have trouble with blockage in the EGR supply pipe. This is usually caused by corrosion, and often times the pipe itself has to be replaced. It has nothing to do with the EGR valve...their failure rate is almost non-existent. J >What's the best way and or cheapest way to fix my 1997 Honda Accord EX v6 >PO401 EGR flow fault?

Is cleaning or replacing the EGR supply pipe a DIY-able task? |
