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?
