CODE P0430 GMC


As the code description implies the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first.

Check engine, I fix the prob get another code, going on 4 YEARS, SMOG STATIONS FIX CODE EVERY YEAR , GET CAR BACK AND LIGHTS BACK ANOTHER CODE, ONE CODE NEVER FIXED IS INTERM SHORT, CHANGED COMPUTOR


If I were guessing, I would suggest you:

1. Take it to a different mechanic.
2. Take it to an auto parts place and get the code read.
3. Give us more information. Start with the make/model/year/engine of your car, and then give us a real history of what was fixed every year.

With just what you tell us here, it sounds like you either have a lemon that cannot be fixed, or your mechanic sees you as an annuity, a ready, regular source of income, or both.

Check engine light. fixed but did not pass smog. light came back on


Get the code scanned again.

If it is the same code, the problem was not fixed.
Could also be another problem that came up while fixing the 1st code ( i.e. knocked a vacuum line off ).

If you do not have a code scanner, Autozone will scan the code for free, get the actual code number and post a comment back to this problem, or start a new one with the code number, and what you have done to this point ( include the 1st code and what you did in what order when attempting to fix that one ).

Replace the alternator, check for loose or corroded connections. The late models are very sensitive because they are monitored by the computer now.
