po430 is catalyst efficiency below threshold ( bank 2 ). in most cases its a worn out convertor. po430 -possible causes The catalytic converter is no longer functioning properly An oxygen sensor is not reading (functioning) properly There is an exhaust leak, good-day !!
PO133 indicates that your front oxygen sensor is not controlling the engine properly .. thats usually a bad oxygen sensor .... in some cars thats easy to change. you could do it if you have any mechanical abilities .. in other cars its nearly impossible, it takes special tools and patients beyond human .. hopefully yours is one of the easy ones .. the part itself might be less than a hundred bucks at an auto parts store but more than that at a dealership . other things that can cause this ... if the wires going to the oxygen sensor are damaged .. and if there is a significant exhaust leak (you should hear that) .. usually changing the oxygen sensor will fix the problem ..it has wires going to it and it screws into the exhaust system somewhere between the engine and the catalytic converter. if you give your auto parts store the make, model, year and engine size of your car then they can probably show you where to find the sensor .. if you are not mechanically inclined then find a mechanic with a good reputation forget lowest price .. i find that often the auto parts store can recommend someone if you ask ..
check the battery and make sure it has a fully charge,also check to make sure the start motor pinion is not jammed in the flywheel, and check the coil pack to make sure have spark.also check the crank sensor
