You did not mention whether you have the 4 or 6 cylinder engine, but the EGR
valve looks like this:

QQ19972001QQW0133-1603325.html

The EGR valve for the 4 cylinder is pictured but the one for the 6 will look
pretty much the same. The EGR valve is attached with 4 bolts - 2 on the
inlet and 2 on the outlet. Remove the EGR valve and the metal tube attached
to it, and dig out the carbon buildup from inside the EGR and tube with a an
old screwdriver or awl. Get out as much as you can and shake out the
crumbs. If that doesn't work, replace the EGR valve and tube if they are
clogged.

How is the tube detached in order to clean it? Are they other parts to clean? If it is a blocked tube, how deep down do I need to go, while clearing it? Thanks.

At 130,000 miles, there is a fairly good possibility that the EGR tube is blocked, especially if the car has mostly city miles. The EGR tube is the metal tube that is attached to the EGR valve.

How many miles are on the car? With the engine idling, apply vacuum to the
EGR valve and see if the engine starts to idle roughly or start to die. If
that happens, check the EGR position sensor. If the engine does not start
to die, check the EGR tube for blockage. Most likely, the EGR tube is
blocked with carbon buildup. If that is the case, you can try to dig out
some of the carbon or replace the EGR valve and tube.

Hello, My Camry '97 just failed inspection. It is code P0401. 'Exhaust Gas Recirculation Flow Insufficient Detected.' Would you please give me your recommendations. Thanks, Talal Itani
