1997 Toyota Camry Q&A
1997 Toyota Camry Question: Code PO402 EGR problem detected-Mechanic tested system-no problem found.
Engine light came on at 123,000 mi. and was intermittent for a few thousand more miles when it finally stayed on. Mechanic could find no problems. Smooth engine & transmission performance with very good mileage. Now have 192,000 mi and still going strong. I live in No. Arizona so don't have to take smog test. I want to give car to my daughter in Los Angeles & need to pass test. Any ideas? - opped
Have you thought about turning off trouble codes? Give it a try, and see if the code comes back on. Chances are, it's a false code and won't come back on. Have you replaced the EGR valve yet. Goodluck - helpfull4u
