So i went into advance auto today to grab the OBD II becuase I knew my camshaft sensor in the bank 1 was throwin the service engine soon light to me since its been hard to turn over the engine when i first start it...then I got another DTC code - "DTC that caused freeze frame - P1621"...after finding mr.dolla's thread this is what it read - "P1621 Control Module Long Term Memory Performance/ Immobilizer Code Words Do Not Match"....what does this mean for me?
