EGR Valve Control Solenoid Vacuum Switching Valve for Toyota

I spent about a week trying to track down the problem for a "P0401 EGR Insufficient Flow Detected" engine light code. There are plenty of videos on YouTube telling you all the wrong things to replace, and others that are 20 minutes long of just testing before they conclude that it could possibly be this valve. Trust me, this is your problem. I have a 1998 Toyota Camry, and after installing it *read the next paragraph* the code disappeared. I tried replacing the EGR Valve itself and the EGR Valve Vacuum Solenoid Modulator before this, and both of those were a waste of time. If you plan on taking this job on yourself, it is important you know how much of a pain it is. If you are not confident jacking up a car safely, or have a lift. You shouldn't do this job. You will want to take off the passenger tire, and you will be in a very compromised position if the car is not jacked properly and it was to fall. Second, it is in a horrible spot, I have long arms and it was a STRETCH to get to the bolt, two hoses, and plug you need to remove. Also, it is difficult to see what you are doing. Install is a breeze in comparison to the removal. The tools I used were a 10mm socket for the bolt, plyers to gently break loose the hoses, and the plug comes out by squeezing the "button," facing you. I tried getting the bolt off with a short socket wrench, but had to switch to a longer one because of how tight the bolt was. It was easiest to remove the outside tube first, then the plug, then the bolt, and finally the tube behind the plug. Good luck, this is definitely your problem!

Solved my p0401 issue for a few hundred miles and then the check engine light went back on. removed the part and ran some tests (see video) on it. When vacuum is applied and the terminals are energized, the switch closes as it should but upon disconnect, intermittently (mostly) gets stuck in the closed position. What a pain to have to go through the process of replacing this part just to have it fail. Hopefully the replacement part fares better. Gave two stars instead of one because it was inexpensive, so my bad for thinking i'd have no issues with it. EDIT: got replacement valve. does the same thing - greater or equal to approx 10inHG vacuum applied, valve will not open when de-energized. two bad valves in a row, really ? NoYall. One star.

Got the P0401 OBD error on 1998 Rav4. First had to rule out issues with the other EGR components (there are few videos on YT on this. You'll need a hand vacuum pump that usually comes with brake bleeder kits to test. You can rent one from auto parts store). When the other components checked out, it had to be this valve. Getting to this on the RAV4 is a PIA. You can get to it from underneath rather than by passenger side tirewell as some videos show. It's attached to the engine by a 12 mm bolt that is hard to get to because the original valve has a short bracket. So you'll need a wobble socket and long handled wrench to get to it and have enough leverage to remove. If you need to, bend back to old valve so you can see and better access the bolt. The valve has a push button electrical connector and two tubes (one from the EGR valve and the other from the EGR modulator) Just make sure to keep track of which tube goes where. If you cross them you'll make things worse. Thankfully this replacement valve has a long bracket so replacing it in the future will be much easier.

Excelente funciona muy bien

Worked great

On my 1999 Toyota Camry have moved it to the top of the engine so it's easy to test or replace. Very happy with its performance!

Difficult installation isn't the parts fault, but it's such a pain to install on my 01 Camry, I regretted not buying the OEM part when it failed.

Fixed my recirculation code. Very simple install but I would recommend relocation.

Quality of product !
