I had the same code. Apparently this can be caused by a loose gas cap. Mine was tight but there was minor rust around the top of the fuel pipe where the cap goes on.

I took some sandpaper and did a light sanding around the opening to get a better seal. Problem has been gone for a year now. Same gas cap!

SOURCE: check engine light on-code says egr valve is bad

the egr system consists of control circuits as well as the egr valve itself. troubleshooting will have to be performed in order to pinpoint the fault. the valve may just need cleaning. there may be damage in the long run since the egr system introduces exhaust gas to the air intake to reduce combustion temperatures.

SOURCE: i have a 1999 toyota

there is also a vac. switching valve for the egr that also goes bad.to find the valve follow the vac. line that is hooked to the top of the egr to the valve.it is located on the back of the motor up under the intake and is a pain to replace. if you have a hand held vac. pump hook it to the egr valve and pump it up and see if the engine dies if it does i would replace the vac. switching valve.if it does not die then i would start looking for carbon on the inside of the intake on the back side of the throttle body plate.and also carbon will build up at the intake where the egr bolts to it...before i messed with the vac. switch i would look inside of the throttle body behind the throttle plate and see if the passage that goes to the egr valve is stopped up with carbon and you will need a small round mirrow and a flashlight....if the car does not die when you do the vac. pump test it is easier to take the throttle body off to clean and to check....been working on toyota and lexus for 25 yrs and have seen it all so let me know if i can help in any other way..........good luck and if i did my job let me and fixya know and a thumbs up............thanks.......

SOURCE: Difficulty to replace EGR valve in 1999 totyota camry 4-cyl automatic

Not difficult at all to service the EGR Valve using a #12 mm socket wrench it is a five minutes job. However the VSV is another history and very difficult to be reached unless you have an elevator After the engine begin stalling I double checked the EGR which was completely carbonized. I cleaned it and also replaced IAC checked VSV and all sensors, but the engine follows stalling. Now I am looking for the Charcoal Canister which I simply can't find where it is located, then I will check the vacuum lines and the transmission sensors, but I have heard that EGR despite cleaned can keep bringing troubles. By the way, anyone has ever heard where in the car is installed the charcoal canister

1999 toyota camry 4 cyl check engine light on code reader said egr valve

A common problem for egr failures are the modulator valves, the valve is attached directly to the egr valve, it's a round plastic housing with three vacuum lines on it, try replacing this valve.

2005 magnum p0406 egr valve sensor code error

P0406 indicates high voltage on the EGR sensor circuit. this is recommended for every 30,000 miles be inspected. although EGR system do not requires periodic inspection. instead, check only if engine trouble's develop. most EGR's requires replacing EGR valve, cleaning passages and installing new vacuum hose. misrouted vacuum hose causes engine poor operation. so. not just to unplug it.

Need to find location of egr sensor

A 2000 Camry with a 4cyl does not have a EGR sensor. The ECU uses the readings from the MAP and AF sensors to determine if the EGR is working.
You have a EGR VSV (vacuum switching valve) and a EGR modulator but no position sensor. Only the V6 has this.

OBD code 0401 (1997 Toyota Camry 4 cyl)

There is a VSV (vacuum switching valve) , usually mounted on the back side of engine block, under the intake manifold, as well as the map sensor, that can also cause that code if one or the other is faulty. It takes some pretty detailed troubleshooting to confirm this in some cases, so if that's not in your line of work, you may have to have it properly diagnosed, or take a 50/50 shot at which one first.

2000 toyota camry v6 code p0402

The egr valve on that motor has a egr positioning sensor mounted on top. The sensor goes bad and the ecu can't determine the how far the valve is opening so it opens it too much. This causes surging of the engine under light throttle application. Also as stated above the egr can stick causing rough idle. Either way if you get the valve from the dealer it will come with the sensor solving both your problems.
