    my 1996 Infiniti Q45 check eng light came on. Took it to auto store for comp check, states knock sensor 1 circuit malfunction. as well as camshaft position sensor a- bank malfunction. How soon should I rush out an have this fixed and/or could this be a problem from bad gas put in @ one time? I'm not sure how to go about this matter being told several different stories, could be because I'm a woman with No Clue as to what needs to be done.
    Some one PLEASE HELP! Other than check eng light car runs well sometimes slightly slugglish.....

What is the symptom? do u have a trouble code for the knock sensor? It is a part that is seldom replaced because of the way it works it has a very low failure rate. The sensor is always screwed into the water jacket of the eng block, look up a picture of the part at an on-line parts store like www.rockauto.com, then you will see what and where is is.

    Clear the code and run a better fuel, it may also just be a fluke.

I would go with the engine being bad.
A knock sensor only sends a signal to the engine computer when there is a vibration or noise like a spark knock. The computer then adjusts spark timing to compensate.
If the engine is knocking such as a bearing knock, the sensor will be activated.

Where can i find the knock sensor on a 1995 infiniti g20


The knock sensor on this vehicle is in a hard-to-get place between the engine and the firewall. I had to remove five or six coolant hoses and a metal cooling pipe that is bolted behind the engine in order to change the stupid knock sensor. Total time was about 15 hours and several trips to the parts store.
