I had two codes a p0031 bank1 sensor1 02, and a p0328 ciruit high input bank 1, or input 1 knock code. I replaced my bank 1 sensor 1 02, due to the wires being sheared, and shorting the sensor out, and the 02 is now fine, and I also replaced my knock sensor. Figuring maybe the knock sensor just went bad, despite everyone saying they usually dont. Well, the code went away for one night, and popped right back. My car runs great, until it warms up, then loses about 15% power, and stalls out when hot every trip I take it on, then the slip, and vdc lights pop up, and it takes about 4 seconds of cranking while pumping the pedal to start again, and the lights remain on, while killing my power by about 30%. I am thinking maybe a CPS, or I dont know, all my wires seem to be fine, and I can figure out what circuit high input, bank 1 or input 1 mean. I'm sorry, but I've searched everywhere for info, and the dealers around here are jackasses.. Any help would be greatly appriciated.

Did you check the knock sensor wire harness?I had the same problem your describing.Except it was throwing p0327.

Whats a 0327? Circuit low? I checked the wiring the best I could visually, but I need to get in there with the tester I guess.. Could a Crank position sensor throw a knock code? There has to be something else associated with this damn circuit high, bank1 or input1, it does seem like a harness problem though..

There have been several people here, including myself, who had the knock sensor P0327 code. I just recently got the code a few days ago. After talking to a few Z owners, the knock sensor harness must be changed also or you will still experience the problem.

Call Courtesy Nissan. They have the knock sensor harness for around $40.
