Computer problem
2001 Hyundai Elantra 4 cyl Automatic 49000 miles
3 months ago the malfunction indicator light came on.The obd scan showed 2 sensors. The first was PO 711 relating to the transmission fluid templative,and the second wasPO 139 bank 2 sensor 1.These were replaced and the light went off.Two weeks later the same light came on and now the scan is showing a few more in addition to the first 2.There is a PO442 indicating evaporation emission leak and a PO455 gross leak no air flow.Will I have to replace all the sensors ? or just the 2 additional latter ones.Could it be due to a faulty catalitic convertor? is this indicative of some other major problem.If i am getting it repaired should the mechanic check for the cat convertor first?
