    Re: P0327 how to fix

    PO327 could be a KR senosr unpluged or if you have messed with the KR decay in Hptuners to make the KR sensors less sensitive. On mine I use resistors and have my KR sensors reduced 40% and mine would throw the low voltage so I just put No Error reported on the code. My car will still show KR just not as sensitive, no audibile KR or anything like that. The other don't know for sure but I think is a O2 votage, so I would first check all the connections and connections at the PCM to make sure wires are not pintch.

              If you messed with the Kr decay rate etc. in Hptuners it might other than that a bad KR sensor or loose wiring.
