Car Forum / Toyota / Camry / June 2006Help: P0401 and P0406 ???
I have a 2000 Camry LE 2.2 Went to autozone and the CEL code came back with: P401 and P406. This is what I found on P0401 Exhaust Gas Recirculation Flow Insufficient Detected P0406 Exhaust Gas Recirculation Sensor "A" Circuit High I had P401 before and the dealer changed out the 1- vacume S valve assy 2- egr vacume valve assy and that was like 14 months ago in Tx. I am in FLorida now. They have 24 months warranty but works needs to be done at their service ctr. I might try cleaning the EGR tomorrow. Cos http://www.autoshop101.com/forms/h61.pdf mentions that there are 3 components to a EGR system. Any idea what P0406 means??? How do i fix it??

The ports should pull full engine vacuum when the throttle plate is opened past them. Check that the EGR valve is working by pulling a vacuum on the valve. The engine should run rough or stall. It's not likely the valve or sensor will go bad, it's such a simple system. They usually plug up first, if even that. You should also check to see that the EGR pipe (from the exhaust to the valve) isn't filled with carbon. You might have gotten a bad EGR valve assembly. > I have a 2000 Camry LE 2.2 > [quoted text clipped - 20 lines] > > Thx I cleaned out one of the egr sensors with seafoam and the light did not come back on i also clean the cable that came into the egr sensor.. lots of carbon in there > First check that the EGR control ports in the throttle body is not > plugged up.
