I searched and didn't find the answer.

I need to replace my knock sensors but I find round connectors on the Bosch sensors and square connectors on the Ford sensors. Does anyone know which is correct? I am unable to check my truck until tonight.

 

Umm.. I would go with the Ford sensor. Can I ask why are you replacing the knock sensor ?

 

the code keeps popping up. I used to be able to clear it and it would disappear for long periods but here lately it pops back up almost daily.

 

Gotcha..

 

Got awfully busy and have not been able look at this at all.
There is a rectangular connector and a round connector. I cannot find any info about which I have.

P0325 pops up every few days. I clear it and a few days later it pops back up. Is there any other issue I should investigate?
