How would you know if your knock sensors have gone bad?
How would you know if your knock sensors have gone bad?
IF the knock sensors are over active and report an issue, you'll know they're bad because a dtc will set.
however, lots of trucks have sensitive knock sensors; which can cause powerloss, hesitation and overall drivability issues.
typically, the codes set will be due to a circuit.
if you change the sensors, change the sensor harness also.

Man the truck in ur avatar is b!tchin. If i could build a strictly duck season truck it would be that color with maxx4 camo accents!
Do u have more pics of it?
If you have your intake off for anything, check the condition of your knock sensors too. The foam piece that's there under the intake to keep dirt out can keep water in and rust your rear sensor pretty bad. My front sensor looked brand new compaired to the rear on, replaced both and the harness with an upgraded one like Allen said.
Yeah I'm gonna switch out my knock sensors out this weekend. Where did you order the sensors and harness off of? Or from where did you get them?
The sensors I just grabbed from autozone along with some rtv. The harness I picked up from the dealer, I don't know if there's anywhere else to get it. That and it was cheap so I didn't care.
