Once in a while my GT throws the p0430 for bank 2 (have headers and high flow catted x). Before, it wasnt really a problem to me. NOW, its starting to get annoying... because my inspection is expired and I cannot pass for a new one.

Whenever I plug in my tuner and clear the p0430, it clears all the data for the catalyst, EVAP, and other monitors that are checked here in New York. Then it throws the p1000 and it wont pass inspection testing because "the systems arent ready". I didn't know that... anyone have a way to clear this p1000? I've read about the Ford Drive Cycle, but is there a simpler way?

Do a search, there's several solutions to this and the P0420 code.
Easiest is to get a spark plug anti-fouler and put it between the driver-side rear O2 sensor and the hole it mounts into. That moves the sensor out of the stream enough to not trigger the code in most cases. (P0430 is driver side, P0420 passenger side).

Is there any way I can use my Sct Sf3 tuner to change the ECU from reading bank 2? I don't want it to come on again during a drive cycle

Also, should I go underneath and swap the sensors? That way I could test and see if one of then is just on its way out. Unless there's another way of telling.

Try the non-foulers and put them on both banks. You cannot rig your tuner to stop the codes. Bear in mind that the non-foulers didn't work for me when I was using the hi flow cats. I even doubled them up and no dice. I had to switch to Kooks Green cats to keep the 0420 & 0430 codes away and pass OBDII insp.

P0430 is your camshaft position sensor. It doesn't matter what bank it is cause there is nothing wrong with it. It is your alternator. Replace your alternator and all will go away. I drove on mine for three years with the codes. Then driving down the highway in the middle of nowhere it died.

If you need to pass inspection there are some ways to clear codes and make them not come up for a brief period. But the solution is within your alternator.

For the headers, if you are not tuned, it needs one. You can put anti foulers and such on but they do not always work. The computer needs to delay it's O2 sensor reading. Moving the O2 sensor down stream slightly makes the sensor warm slower which throws off the computer.

So the solution to your problem is a tune and alternator. If you already have a tune for the headers, then some other things come in play.

No, p0340 is the camshaft sensor error code...p0430 is catalyst efficiency bank 2.

you could swap the sensors, clear the codes, do a few drive cycles, and see what it does; that's not a bad idea, but most likely, the 430 will return. If it changes to a p0420, then you know the sensor is flaky.

I hope it's just a bad sensor. This has been happening since last year when I put these in. I've never gotten a code for the right side cat yet. Im going to swap them and see what happens.

For a while now though, I've had an exhaust leak I believe at the end of my X to the overaxles, and my suspicion is the drivers side because I smell it a little while at a red light. Would this cause the code?

that's the second time lately I've transposed numbers for CELs.....crap..

l00kitzzlilcj

Lol its no big deal everyone makes mistakes.

That might actually help me Simon1... I've been getting random shutdowns (P2105) and P2135 persistant CEL with P0340, and (forget the #s atm, but fan #2 ckt and evap purge ckt).... I wonder if it IS the alternator... though my voltages are all good... weird
