How to fix a code B0320 - 1998 Dodge Ram 1500 4WD

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.

P0301 - OBD-II Trouble Code - RepairPal

You have to find and fix the fault the code relates to , delete the code then test drive to make sure the code does not come back if it does the fault is not fixed.

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.

I'm looking at the code book and ALL codes are 4 digit codes, EX POO56, POO57 and PO161. If these are What you are getting, they all are codes for the left and right hand oxygen sensors. Could be wiring, Sensor itself or ECM

p0033 code. It is a Turbo Charge Bypass Valve control circuit code.

p420 code has to do with your exhaust system,catylic converters,..sensors...could be a simple fix or not...

Have to pay someone with professional tools
to get the car ready for inspection

I wouldn't give my money to any dealers

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 ).
