80k miles, getting this code, PO406, EGR Flow Sensor A High Input.

Assuming the EGR valve is stuck, I have located it, was wondering should
I pull it, clean it up and lube it with some lithium grease, or sohould
I diagnose further. Don't mind getting another one and installing it
right off the bat if I'm reasonably sure it's defective.

Any pointers? Appreciate any help!

yeah, I talked to brother in law who is a certified Toyota mechanic, he
said the same thing. Ordered one today from Rock Auto, along with every
heater and radiator hose.

So a little more info. I had pulled the air filter, air duct etc, to
take a look at the EGR valve, cleaned the K&N filter which was preety
clogged up. My bad on that. So today my wife asked what I did to stop
the check engine light to stop. I said all I did was clean the air filter.
