2010 Kia Forte ex die on highway will not start said engine said nothing does anyone no what this means cat evap Oz's hrt egr


Instead of Oz's hrt egr, the computer is referring to the O2 heater, and your Catalytic converter is Overheating because of the resulting rich mixture, this triggers an automatic shutdown or limp home mode for your engine. You need to get your trouble codes read, so you know which O2 sensor is bad.

O2 sensors keep failing and a evap leak code i put new gas cap did not cgehan ssomers11@gmail.com


Are you sure it's 02 sensors? Just because code says 02 sensors doesn't necessarily mean they're bad. Bad 02 sensor code can also indicate bad cat. converter. If 02 sensors read exact same reading before and after converter they will trigger OBC to "sensor fault" - they should be reading 2 different readings. (Pre CAT/POST cat) I'd suggest replacing cat converter before replacing sensors.

Nissan fronteir codes are P0420, P0430 what has failed


po420 and430 is telling that the catalyst converters are no good both, most of the time bad o2 sensors maake computer think cat is no good, the way it tests is if o2 sensor reading before cat is about the same as the one after cat computer asumes cat is not bruning exhaust good , iwould replace o2 sensors reset check engine light and go from there, that might be the problem,if you were to replace cat o2s should be done at that time,so do o2s first,good luck.

Catalyst system efficiency below threshhold bank 2


before replacing cat converter replace o2 sensors, they go bad and give a false reading that cat efficiency is below threshold ,meaning converter is no good , i would replace o2 sensors and reset engine light and go from there,the o2 s are normaly the problem, unless you hear cat rattling, well good luck,

1999 Mazda Protege ES/1.8L Manual Trans


cat is probably gone if it is the stock one, but i also know the mass air flow sensor could be the problem, and its also the cheaper of the two things you could do (MAS or pre-cat). you can try cleaning it with the spray stuff they sell at any local auto store. readings online say this car running rich will kill the catalizer in two weeks so you might want to keep that in mind.
