    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.

    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
