 Code-PO327 Sensor 1 low input(Knock sensor)
My question is is it the knock sensor setting this code or o2 sensor? The passenger side has a new o2 sensor in it. My car has thrown occasional knock sensor codes, but now it will not go away and performance at the track is hurting, so I believe it's cutting timing. The description of the code is throwing me off(low input), does that mean that sensor is bad, or that a bad o2 could be throwing this code(driver side o2 is older than passenger).
