        2001 Silverado. Easy to install once you get the intake off. Replace wiring harness as well. Use RTV sealant on new harness per GM. Keeps water out. Got rid of my knock sensor code. Be carful during install as could cause vacuum leak at intake.

        Comments about Delphi Ignition Knock (Detonation) Sensor:

        Did the 3 hour replacement job only to find out that instead of one rear sensor code I was previously getting, both (front and rear) now came on after 50 miles. Reset the code and both came back every 75 miles or so.

        Decided to try AC Delco KS instead and have had no problems.

        Helpful hints for 2003 Suburban 5.3 Flex Fuel:
        -Make sure you only torque these to about 15 ft lbs. They are sensitive.
        -Get some high heat gasket sealant to make a half circle in front of rear sensor and rubber housing (Chevy 5.3L has horrible design for these and will get water in them)
        -Buy new wiring harness at the same time. Old wires and plastic can break during this.
        -Will need a 22mm socket to get these out of Chevy 5.3L
        -Get carb cleaner at the same time as you will be taking apart the manifold and it only takes and extra 5 minutes to clean both sides of the butterfly in the TB
        -Clean MAF sensor at same time
        -Replace Manifold gasket as you will have the manifold off

            I replaced these on my friends truck after I had already done them on mine. Friends was a 2001 chevy 1500 and now there are no codes at all. Siliconed around each one after install too keep any water out and the codes are all gone. Good to do if you're replacing intake gasket or already have the manifold off. Great product though, fits and works perfect.

                A:

                The knock sensor on your 2003 Chevy Avalanche should be located in the intake. The intake manifold will need to be removed to get to them. The wire harness and intake manifold gasket should both be replaced when reassembling.

                The knock sensor on your 2001 Chevy Silverado 2500 should be located under the intake manifold. To replace the knock sensor get a long extension for your socket wrench, get the adapter that allows for a few degrees of movement and get a long pair of needle-nose pliers.

                A:

                Knock sensors detect abnormal vibrations in the engine. The system is designed to reduce spark knock during periods of heavy detonation. Knock sensors produce AC output voltage which increases with the severity of the knock. The signal is fed into the PCM and the timing is retarded to compensate for the severe detonation.

                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.

                Yes, it has to have the wires to send signals to the engine computer.
