I recently purchased a 1999 Toyota Avalon and as soon as we drove off the lot, the check engine light illuminated. I took it to AutoZone, where they diagnosed two trouble codes: P1411 and P1410. What should I do next? Should I return to the dealership or take it to another repair shop? And is there a legal issue involved if the codes were intentionally cleared?
P1411 refers to a fault in the EGR Valve Position Sensor Circuit Range/Performance, while P1410 relates to the EVP (Exhaust Gas Recirculation) sensor. As these are emissions-related codes, it's advisable to return to where you purchased the vehicle—especially if they are reputable—and have them resolve the issue. Good luck and please update us on your progress.
Thanks—I inspected the car and discovered that the seller had left behind their diagnostic tool and key book. I spoke with a Toyota dealership, who confirmed the same diagnosis. I'm now consulting an attorney because it appears the seller intentionally cleared the check engine light code. This may be illegal under emissions regulations.
There's no need to hire a lawyer immediately. First, try having the issue repaired—sometimes it’s a simple fix. While it is illegal to disable or bypass the check engine light (CEL) by splicing circuits, clearing codes through software may not always be illegal. However, installing a new battery can also reset the system. As a buyer, you should have a qualified mechanic inspect the vehicle and verify that all emission monitors are properly completed. Please let us know how it turns out.
Since the check engine light came on immediately after driving off the lot, you should return to the seller and have them address the issue. If they refuse, consider taking it to another repair facility and request reimbursement from the original dealer.
