THE KNOW SENSOR IS RETARDING YOU TIMING< PROB EVEN SAVING YOU GAS (hint hint - CAPS)

You can get yourself a factory service manual for $20 and save yourself a ton of money fixing things yourself

I wouldn't worry about the knock sensor unless you can tell knocking is going on - I think it is more of a phantom code on the 3.3. pathy

phantom code?

I decided to hook up my OBDII and it gave me a coke for the knock sensor circuit. I had no engine light on or anything. I decided to just scan it. I removed the code but it always comes back later.
I hear no pinging or anything out of the ordinary.

Is this common?

Very common, yes. The knock sensor should not cause excessive consumption of gas. O2 sensors, dirty MAF sensor and poorly-maintained vehicles with high mileage, however....

I meant o type "code" not "coke". I must have been thirsty.

Just so some of you know, the 3.3 liter engine isn't a fuel effecient engine at all! This is why Nissan went to a 3.5 liter, timing chain engine. This 3.5 is great in gas and has more power. Btw, the knock sensor can't be removed on the Pathy 3.3 as easy as the Maxima 3.3 cause of the design in the intake and also cause of the engine position.

Just replaced knock sensor in my 97 pathy. PITA - had to remove intake manifold (took me a couple hours as there were tons of connectors, vacuum lines, etc.). If you are going to do this , might as well change the Valve Cover gasket as well (if it has not been done in a while). Will save you a lot of time as manifold is already off.
