1996 Hyundai Elantra code
I bought a code reader and it works.
The code is: P0422: Main Catalyst Efficiency Below Threshold (Bank 1) Anyone have experience with this? Possibly an O2 sensor? |
Re: 1996 Hyundai Elantra code
The converter is probably bad. Check both oxygen sensors to be sure
they're operating properly. If so, you'll need a converter. I've only seen this code once where the vehicle didn't need a cat, and that was on a Sedona where the engine had been replaced and the mechanic apparently was colorblind; he swapped the front and rear oxygen sensor connectors. I don't think that's a possibility on your vehicle, however. Any chance you're still within the 8/80 emissions warranty?? |
