Well you should verify the code is the same, then have the problem repaired. Saying "It's EGR it's nothing to worry about" was unprofessional and should not be accepted. A better answer would have been "we know we don't sell the part that fixes this, it is a Toyota only part"
Your EGR system needs to be functioning correctly for proper engine operation as well as for correct emissions and optimal fuel efficiency.

I will go out on a limb and say that I suspect you have the 5SFE 4 cylinder engine?

These engines commonly have the EGR VSV fail, causing the incorrect/insufficient EGR flow code.
The VSV is an electrical vacuum switch that is located on the back of the engine... unfortunately it is located right below two very common oil leaks on these engine, which is what usually leads to it's death, if the heat doesn't kill it first.

The VSV is not technically difficult to replace, but you need to be a kind of flexible as there are some tight crevices you need to get your arm through to reach it. For this reason it is best left to a shop that has a lift for better access underneath the car.

Check engine light is on took it to auto zone they said it was my egr valve and i replaced it and check engine light still on........ is it any other sensor that, the egr could have trigger


The check engine light will not go out on its own until usually after 20 or so starts.You need to back to Auto zone and have them hook up the analyzer again and clear the codes (they will do this for free). If the problem was your EGR valve, the light will then go out.

1998 Accord EX V6 engine light on / put it on the computer, which said EGR valve was bad / bought new EGR valve for @$160.00 and swapped it out myself plus disconnected battery for 15-30 minutes to reset...


Check the EGR vacuum regulator and make sure you have battery voltage to the solenoid. If voltage is present then check the regulator resistance. To check resistance you need to remove the wiring harness and using an ohm meter make sure that it is within your vehicles specifications. You can also try testing the vehicles Differential Pressure Feedback Sensor.

How do i replace the egr valve sensor


The Vehicle would only stop, if the EGR stuck open,momentary at low speed,and dumped too much exhaust into the intake. The entire EGR Valve ,if bad, needs to be changed. The sensor is part of it. Have her find a good shop or a friend do it at home. Pretty easy.

Can't pass state inspection, changed EGR valve already, next?


I suggest quit hunting for maybes and rent an OBD code reader which ends up being free when you return it to the auto parts store. Connect it and find out what is causing the CEL condition. Normal issues are the O2 sensor, or sensors in the system.

My Check Engine light was on and I took it and had Auto Zone test it.The problem was my EGR.I was wondering where is it located and is this a common problem.


Look on Auto Zone's website for a picture of the EGR valve....usually located near the top rear of the engine. You can try cleaning the EGR with some carburetor cleaner as they usually get pretty fouled up with carbon deposits, just remember to replace the gasket when after you remove it. If cleaning the EGR does not help, you may need to replace it.

Per Auto Zone, the EGR value needs to be replaced (check engine light is on). Where is the value located and should I try to remove it and clean it? Is there any other items suspect for replacement with...


The EGR valve is located on the intake manifold, it has a single vacuum line going to it, are you sure it is the valve and not the vacuum control valve that opens and closes the EGR? You provided no year or trouble code, so hope this answer is correct.
