YES.. it is possible that MAF sensor is bad causing this code. The o2 sensor before and after the converter could also go bad causing this code as well. I have even seen vacuum leaks and exhaust
leaks go bad causing this exact code. You are going to want to have the fuel trims checked with a scanner that can read the live data with the engine
completely warmed up both at idle and under a load. They should read close to 0%. Both sort term and long term fuel trim. An allowable amount of up to 7% in either direction is ok.. but no more than 7%. If all of the numbers are good, no intake or vacuum leaks are detected and the MAF and oxygen sensors
are all ok, then yes.. the converter needs to be replaced. YES.. it is important to use original equipment from the Toyota Dealership.
