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

How hard is it to replace the EGR valve in a 1999 toyota camry 4-cylinder engine with automatic trans.? The local dealer wants $550 to CLEAN the EGR valve on my coworkers camry, when a NEW one from a local parts shop only costs $180! Also, should she replace the vacuum line at the same time? The EGR valve gave her quite a problem a few years ago until it was finally replaced AND the vacuum line was cleaned or replaced.

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

If you have small hands it can be easy. The space between firewall and EGR is tight but it wasn't too difficult to remove. The vacuum hose at the bottom was hard to pull off and I ended up cracking it and had to splice it. It was more difficult to re-install the EGR then remove it. I had a difficult time with keeping the gasket aligned while bolting it in to the lower tube. I took a few attempts. I suggest when replacing the EGR leave the mounting bolts loose so you can more easily align the metal tube. I would tighten the metal tube at the bottom of EGR first then tighten the upper two mounting bolts on top. It took me about 5 minutes to remove and 15 minutes to replace. I would be sure to clean the IAC too after cleaning the EGR. I sprayed throttle bottle cleaner down the bottom hole located on the throttle body and let soak about 15 minutes then start and run the engine a minute and repeat the process. This helped smooth the idle while stopped at a light. It also stopped the idle from shaking and almost stalling the car out at a traffic stop when the engine was warm.

I have a 1999 toyota camry 4 cylinder with the check engine light code of p0401 and i replaced the EGR valve and still have a problem, what else may it be?

there is also a vac. switching valve for the egr that also goes find the valve follow the vac. line that is hooked to the top of the egr to the 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.......

Our 97 camry check enginlight is on shop says code is for the erg valve, it does not look that hard to change should i just change the valve with the hoses or the whole unit?

Try to change the egr valve, the part with the hose connected to it. That's, of course, that if the egr solenoid is working correctly. Be sure to clean the carbon out of the recess hole that the egr valve pintle goes into.

Good luck on this repair.

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.

Toyota Camry Automatic Transmission Jerking Shift

Not likely to be the clutch pack as you dont mention slipping wich is the normal sign of overheated or worn clutch bands.Not sure with your vehicle but 2 methods that control the shift severity are engine vacuum or pump pressure inside the auto. so check balls are a possibility. They are spring loaded to open at a set pressure,or close.Could you check to see if its a vacuum controled and if so its a lot easier to fix as the vacuum control should be outside the trans.
