99 Camry CE(EGR FLOW) PROBLEM

[213solider]

Have a ?/
My Camry engine light came on and i took it to autozone for a free diagonositc test and
the test gave me a code P0401>
and it said EGR FLOW INSUFFICIENT

does anybody know what the problem is..and how much it will run me to fix it...also is it a big problem or small problem.

PO401 is usually caused by the vsv that controls vacumme to the egr valve. It is the switch on the back of the engine under the intake manifold. I would bet the local toyota dealer has a couple in stock because this is a common part failure.

i left my engine check light for that reason on for half a year and it finally went off

guess it healed itself.

does anybody know how much it would cost me to fix this

My girlfriends car didn't heal itself, it's been roughly half a year too. now it's time for smog. i'm somewhat mechanically inclined but this is something I haven't done before. Anyone know how easy to fix/clean this?

same thing hppend to me on my 96 5sfe, i replaced the valve and also the lines for it, its just 2 lines its not that hard, any who i replaced the valve and reset the ECU, and it went away for like 3 weeks and now its back again not sure exaactly but it might be the ticket to pass smog and you can fix it at a later time
