How many knock sensors in a I6 s320

I replaced the knock sensor under manifold, close to motor oil dip stick, cleared the code and it came back a day later. Is there another sensor that im missing?

Send car's VIN and I can most probably tell how many of them is in your car.

Thanx

for cars up to the model year 95 there is one knock sensor.


for cars from model year 96 there are two sensors so there must be another one. knock sensor(s) is item 72 on the picture. i do not know exactly its position on your car.

Thanks for the responses, I found on another forum, or this one I forgot about a guy who had my same problem and error code and the plug to the knock sensor had both wires touching. I checked my connection and it was the same way. Cleared code hope it doesnt come back, hope it helps someone out there
