Hi everybody. I bought a Rav 4 for my 16 yrs old daughter. She save $ for 3-4 yrs for it. We went and bought it together from a so call mechanic Its a 2003 Rav4 sport with 84000 miles. Her first car, drove it home and check engine light came on at only 174 miles Went to a garage told, me code P0420 + P403 is causing the check light. They turned it off and it came back on 165 miles later same codes P402+ P403. Is this a bad catalytic converter that we will now have to buy for $1300 from Toyota, plus labor. She's crushed. Former owner payed $1500 for a Toyota ECU in June 2015. He says it the just O2 sensors @ $50 each. Thanks any help.
