My 97 Maxima throws the code, my friends 96 throws the code and my brothers 95 throws the code. I no longer have my maxima, but from what I remember this was a pretty frequent issue with the 4th gen's correct me if I am wrong?!?! Im trying to help him out some, and I ran the tests on his ecu to determine the culpret for the CEL coming on, and its an engine coolant sensor and the knock sensor.

Obviously somethings is wrong with those two sensors otherwise they wouldnt be throwing the code. Recommend replacing the knock sensor asap after we check the megohms to determine its status?

 

I understand that the knock sensor detects engine vibration to then relays the information to the computer. But what exactly is going on when the knock sensor is throwing the code. Is it a bad sensor, or does it throw the code cause there is excessive engine vibration? And if the sensor is replaced that isnt going to fix an engine vibration problem.

Were working on a 1995 GLE Maxima. Auto.

Thanks, for any feedback

change the CTS use thread selant on the new sensor. Change out the KS. I've read a lot of people have had to change the KS but I wouldnt say its that goes out frequemtly.

 

and when you change the coolant temp sensor, make sure that the engine is cold, else you'll fry the new sensor.

 

If you want, I've got a knock sensor and coolant temp sensor for sale off my 40k mile motor. $70 shipped for both. Let me know

 

Let me talk to my bro, I will definetly let you know.
