P1332 Knock Sensor CEL after installing new valley pan and seals!!

[bmw5452005]

I am so frustrated. I replaced a my leaking valley pan and all the waterpump seals. New intake manifold gaskets. After driving the car the above code popped up. Car is driving great with no issues. Maybe I hit or stretched the knock sensor wires which were right next to the valley pan.
What is the best option here? I dont want to open up the manifold again just to do this.

Any one can help?

Unfortunately you have to go back and check your work which might mean pulling the manifold inspect. Remember if it wasn't there before the work then check your work
