The answer posted previously seems to be taken verbatim from this site, and probably copyrighted there: Mazda EGR Flow: Low or Excessive? http://www.asashop.org/autoinc/sept2002/techtips.cfm and if that doesn't work, there are additional tips here: P0402 EGR code Help - Automotive Message Forums http://www.automotivehelper.com/topic478910.htm
How do you repair 99 Camry code PO402 EGR excessive flow?
There are multiple causes behind a exhaust gas recirculation (EGR) related OBDII problem codes. For example the EGR on this Camry can be replaced. That may or may not correct the condition. The first steps in solving the problem are isolating the symptoms. For example a catalytic converter failure or problem (which may or may not trigger an OBD code) can cause EGR problems. Without replacing non-faulty components, the vehicle should be scanned with a professional reader-tool that can actuate the EGR to test its function. For reference purposes the EGR for the 1999 Toyota Camry with the 3.0L V6 is Standard Motor Parts/Intermotor #EGV693.
