bzb Posted May 1, 2007 Share Posted May 1, 2007 Hi all, I have 98 4dr accord 130,000 miles. the mil is on with the code p0401 that is the only code. I changed the egr valve and cleaned the port went through the trouble shooting in the shop manual and the code is still there after I erase it There is low voltage to the egr valve 7vlt not the battery voltage like it should be. The manual say's to change the ecm but was wondering if there is a trick I am missing. Thanks in advance Link to comment Share on other sites More sharing options...
