Hey guys, I have a 2004 Nissan Frontier 4wd 3.3l truck which was leaking oil out of the valve covers. I replaced both gaskets and put everything back together again but now I have a check engine light on. When I run it through an OBD I get a P0327 code and a P0732 code. It drives just fine with no issues with gearing or anything like that. Could it be a faulty knock sensor?
