Default PO 530 DTC resistor for AC delete??

Does anyone have a clue as to whether or not a resistor placed into the connector for the AC pressure sensor harness will eliminate this code and the resultant SES light?

I removed my AC system, and only when I go WOT, I get this code and light, after only one cycle
(I am guessing because the ECM is sending a signal to the compressor to cut off and there is nothing there to recieve/confirm it?).

IF a resistor will work, does anyone know what rating I need to keep this code away until i can get it written out by a tuner?

Thanks in advance,

Dave H.

ANYONE???

Or do I HAVE TO have this written out by a tuner (preferably one with a CMR program, so I can still use my Predator hand held tuner), as the ONLY way to get rid of this code?

Also, does the same hold true for the EGR delete, that a re-tune is the ONLY way to keep the SES light off?

No, I still don't know what resistor (IF any) will keep the P0530 codes away when one goes WOT with the defroster setting on the HVAC dial.

I just had a tuner 'write it out'.
