P0332 - Hummer H2 AFTER REPLACING BOTH SENSORS!

Question

I recently had the P0332 code pop on my '03 H2 and I changed out both sensors and installed a new harness for it. I cleaned out both areas where the sensors went and RTV'd the rubber boots back in to seal them from future water damage. However after 2 weeks the code has popped again! Is there another issue I am missing or is there an ECM update for this? Please any info will help!
