so I just randomly checked my codes the other day and came up with knock sensor and engine coolant temp sensor at the same time....anyone else had these two come up at the same time?

 

Replace both sensors, How to replace each are in hte FAQ's and in the 4th gen HowTo's

 

yeah but as most of us know, a lot of times when a code goes off, it is not always that exact item that the code states especially when it is multiple codes all at the same time....ie. research it on a nissan service program like ASSIST and you will see that when you have multiple codes, it is almost always some other weird thing you would never guess that it causing the codes...

 

their is one similar on assist to mine...but that one didn't check out....i cleared my codes and the engine coolant temp sensor went away and has never come back...the knock sensor one keeps coming back after 50 miles or so....i'll just check the resistance of the sensor to make sure it is the knock sensor...
