It's not the valve. I've never worked on an Acura. but it's not the valve. they rarely short out. check the passages, and the vacum pump. hopefully someone with acura experience comes along. good luck.
Ok this guy is a clown. I have never worked on an acura either but it may verry well be that the egr valve is coverd in carbon. The carbon is easy to clean with a wire brush if you remove the valve.The main cause of malfunction in an egr valve is the carbon build up leaving it stuck open or closed! Simple huh?
i have a 99tl that had the same problem. simply remove the intake and clean the carbon from the passages to egr. it not difficult, it took about 15 mins and have not had trouble since, good luck!
Absolutely right! I had a problem where when I drive at a constant speed of 45mph or higher, my '99 Acura TL would behave very weirdly. The engine didn't turn off but even though the car is in DRIVE but still behaved like it was in NEUTRAL, and then it will kick back in and start working again. This happened a lot of times then the check engine light came on. I received the P0401 error code. I bought a new EGR valve from Autozone and replaced it. Works great. However, I do hear a little bit louder noise when the engine starts and I take off, but the Autozone guy told me that it is because there is a lot more air passing through, since the old valve was clogged up.
It is fairly easy and quick to change. I love the performance now!
Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
acura cl 2002 check engine light
how do i reset the check engine light on a 1999 acura 3.2tl
Exhaust gas recirculation insufficient flow detected
Check your engine, or refer to owners manual.

Yes.
I just had this happen to my Ford Taurus, what I've been told is that it is a malfunctioning PGR valve (something to do w/ exhaust). I visited an autoparts store and they had the part I needed for $120 and said it's a pretty easy install for someone who know's cars. Luckly the check engine light went off, which might have meant I had a clog that worked it's way out.
You can take it to a professional, or you can check the reading yourself. A check engine light can mean many things.
