#1

code says engine knock sensors 1 and 2 are bad. can both go bad at same time. After clearing code runs good for a short period of time. has anyone had similar problem.
Thanks


#2

Yes, they can but usually don’t.

Why does that matter? You have the problem now. If you will post the actual P codes, we will try and help you diagnose the problem.

Yes, sometimes rodents nest in the engines valley and chew the knock sensor wiring.
