This stupid check engine light kept coming back after the mechanics replacing the EGR Ports/catalytic converters and nothing seem to fix it. It is so annoying, now the car is 212000 miles and I am giving up on this issue. - John397

Replaced catalytic converter and light is still on. - Visitor
The cat rattled when I purchased the car, allowing me to get it for pretty cheap. I drove it for a while, until the car was so down on power that I couldn't keep up with traffic. I had it repaired for about $300 at a local shop. - curry2013

The check engine light with code P0402 came on around 112900 miles. This problem is because of the engine computers threshold calculated by the 2 oxygen sensors. Accords from 1998-2001 have a much closer tolerance than other year models so as the catalytic efficiency becomes less, these year model accords trip the check engine light. I tried a CATCOE $310.00 brand catalytic converter and got about 20K miles before the same problem came back. I have sense changed it again using a converter from Autozone $190.00 and after 30k miles no problem noted. Always use Honda O2 sensors or Denso brand. Never Bosh - Visitor
EGR valve is bad, has to be replaced for $125.00 - Visitor
