P0327 code says knock sensor circuit low input. 2004 nissan xterra 3.3l replaced sensor problem not fixed no more codes come up smptoms are low to very low power from engine
This is the problem with not doing diagnostics and automatically replacing whatever part is mention in the code. In your case, Nissan seems to be having a problem with wire breakage. Disconnect the connector to the knock sensor on the right valve cover and check for 2.5 volts on the white wire (key on). If no voltage, you've either got a broken wire or bad ECM.
