I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???
My vehicle is throwing a P0401 code. I was going to replace it, but instead I am going to clean it and replace it. I know the mechanic will want to replace it and charge me well over $100 (I'm seeing the part go for around $52-$55). THe car was recently serviced with the valve cover gasket replaced.
I've never seen an EGR valve failure on these engines. It's almost always the vacuum solenoid for the valve that has failed. I've also seen issues with vacuum lines breaking or becoming plugged but that's pretty rare. It's just a shame that so many shops have parts throwers nowadays, get a code for the EGR valve and instead of taking 2 minutes to use a vacuum pump to test the valve, they just replace it, and then not even bother to drive the vehicle before giving it back to confirm their repair... terrible! They are giving the people who try a bad name.
