Howdy,

I've got a '90 Maxima (VG30E) and I've received an error message which suggests that my detonation (knock) sensor is malfunctioning. My local Nissan garage (actually, 2 of them) have stated that 9 times out of 10 this is not the problem. My real problem is: where is the sensor located on the engine? I CANNOT seem to find it and I'd like to replace it so I can at least eliminate that possibility. Anyone dealt with this before?

Thanks!

Cary

 

omg the detonation sensor is like buried deep inside the engine.

 

I looked in my haynes manual and the only thing i can find about the detonation sensor is that "This repair must be preformed by a dealer service department"
