I drive a 1998 ACURA CL 2.3 check engine light went on for the egr valve I replaced it twice, the light went off n about a week later it went back on. I cleaned the passage way and it went off then about a day later returned reading the same code p0401. How can I fix this problem?
have the same problem?

You need vacuum and exhaust at the valve for it to work
common for the passage to block up. Need to clean all the way back to the throttle body.
