Check Engine Light Due to Restricted EGR System on Toyota Camry

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

engine lite comes on--mechanic says it's the egr---passed smog test 3 months ago....mechanic did pressure test and it tested ok, so he reset engine lite, it was off for about an hour then engine lite went back on...not sure what to do now ???
1995 Toyota Camry 252,000 mi,
First cleaned EGR Valve twice...then after that no longer worked I went to mechanic and replaced EGR Valve and after 2 miles of driving Check Engine light would come back on....went to dealer then and they replaced the EGR sensor...and never came back on again.
check engine light came on, this was the issue

Check Engine light,EGR temp. sensor code

This was exactly my problem with my 91 4-cyk Camry - the emission tech was a little too quick to change the catalytic converter and NOx was still over the limit. I took it home, cleaned the EGR tube which was blocked nearly the entire length (the carbon is cement-like) and the car dropped way below the NOx limit. Had to replace the gasket where the tube meets the manifold.
Check Engine light came up due to failed EGR vacum control valve. Fixed for $80 part and $80 labor.

did not fail emissions test, but the "check engine" light went on and stayed on until my mechanic diagnosed the problem --simple and inexpensive fix
1996 Toyota Camry 350,000 mi,
Check engine would come on and go off and then it just stayed on. I need to go to get my emission test. Before I can go I'm getting the ERG vale replaced.
I put it in drive the car barly go but i put in lowe gear it go

Had to replace the EGR valve
I have a 1990 Camry LE, 6cyl. wagon. Check engine light came on. I checked the diagnostic error code which is 71. The repair shop I use charged me $330 for a VSV valve and $170 for an EGR valve plus $140 for labor. The check engine light is presently out but I have only driven the car home from the shop or about 3 miles. The parts charges seemed high to me but the mechanic showed me one of the replacement parts he ordered and it was a very complex and highly machined piece so the price did not seem unreasonable. Today I checked under the hood but I do not see the two new parts that were supposedly installed. So now I am wondering, was I taken advantage of?!
1991 Toyota Camry 191,000 mi,
failed smog test and tune-up failed to fix problem of high emission gases...need to replace EGR and check rest of intake for carbon deposits.
Car engine was shaking a lot and it would shut down when I stopped at a light. Paid about $120.00 at auto zone for egr valve a friend installed it for $40.00 and the car runs like new.
check engine lights on then went to autozone to have it check..its says egr system fault
