Hello make sure who is doing the work clean and dry area where they goes. A water area will short it out and give low volts low watts code. Make sure get intake gasket kit and Dorman - OE Solutions Knock (Detonation) Sensor Harness Part No. 917-033 due to water maybe in the old harness. Will casuing code again after changing Knock senors I still had code til I change harness. Code came up after driving 50 to 100 miles.

Got check engine like and bad knock sensor code on 2004 5.3 Chevy 1500 Silverodo @ 125k miles. Pulled intake manifold, not an easy job and found the rear knock sensor very corroded and felt sure this was cause. Replaced both sensors and wiring harness and upgrade gaskets as not wanting to go back in to replace. Then within 50 miles got same code. Checked with a repair shop and was told that anything but the GM part can give you fits. Advance let me return the BWD sensors and pay diff for the AC/Delco sensors. Replaced about 200 miles ago and no check engine light. Wish I had use AC/Delco the first time and not had to redo the job. Also suggest using rtv around the rubber covers on the harness. Youtube has several videos on replacing sensors and was very helpful. Was quoted $600-700 to do this job at repair shop.

Comments about BWD Knock Sensor:

Better than OEM, comes with a Lifetime Warranty. Has worked great so far, butt only about 300 miles so far. With the cost of replacing them... always replace both at the same time. Even tho only the rear one goes bad, normally because of water in the well. The pig tail should also be replaced at the same time, because the water that damages the sensor also makes the pig tail brittle where it attaches to the sensor. It normally breaks when you try to pop it off the sensor.

      Comments about BWD Knock Sensor:

      Replaced both mine on my 02 avalanche 5.3L. Did both sensors,gasket,and wiring harness at the same time. Took me about 3 hours start to finish, not to difficult if you have a decent grasp on how to fix vehicles. These sensors work great, I see reviews saying they are junk but I can almost promise there is something they either did wrong oar something they broke. That have good weight to them and are good quality. Do not drop these on the a hard surface, if you do they will go bad. Make sure you clean the surface of the engine block and the holes the knock sensors fit into to ensure proper fit for the manifold gasket.

        GREAT PART for the money save over GM price
        please note : repacing the knock sensor is not a easy or fast task plane on about 4-5 hours if you have the tools as the upper intake & fuel inj must be removed to get at the sensor!

              A:

              With reference to your inquiry on this BWD Ignition Knock (Detonation) Sensor (Part No. S8696), the Knock Sensor retards the engine timing when there is a knock or ping detected. This will make the car a little sluggish. It is rare that the knock sensor goes bad.

              A:

              The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the ECM.
