07 Sierra 1500 classic w/4.8. These work perfect! Finally fixed my low power issue. Delphi makes most of GMs electronics so these were a no brainer. I did not have an CEL at the time but always suspected the stock ones were on their way out. They were just overly sensitive. I had no power under full throttle until the RPMs came up around 3K. Now this is like a new truck again!

I used two of these sensors, along with a relocation blocks and harness to fix knock sensor codes on my 2005 Silverado 4x4 5.3 You will need a stubby 22m socket to tighten knock sensors to 15 foot/pounds if you mount them on the front side of the relocation blocks, due to limited space. I did not have a stubby socket, so I had to grind an old 22 mm socket to be able to use a torque wrench to apply the right amount of torque.

I bought these because ACDelco sometimes sources products from Delphi and these were half the price of the ACDelco sensors. My 2002 Suburban had been getting these codes because of the known rust issues with the 2000-2006 design. Anyhow I bought two of these and a new ACDelco wire harness. I did the work of replacing them, codes kept appearing. I thought maybe I had installed them wrong (torque) because the resistance was perfect at 100.3 on the ohm meter and I got a voltage response when tapping. So I did the job again, made sure all rust was scrubbed out, a little dielectric grease, perfect tongue, ground continuity as expected, but the whole thing back together (not a quick job) and the codes came back! I tinkered with resistance on the wires, figured it had to be the wires or ECM, couldn’t possibly be these sensors. I battled this for 6 months (too late to return these) until I asked a neighbor with the same engine to let me check his wire resistance for the knock sensors… turned out mine had been perfect before I started trying to mess with them. Finally bought a pair of ACDelcos from a local dealer and did the job a third time. After pulling these out I compared them with the ACDelcos. The ACDelvos measured 99.8 resistance (perfect, nearly identical to these, but the voltage check with a tap was insanely different. The ACDelcos voltage was way more responsive to taps. Once I put it all back together with the ACDelcos, the codes vanished and haven’t come back in over 300 miles. I’m kicking myself that I trusted these Delphi units and so much money, labor, and frustration are down the drain.

Direct fit with no problems installing them. Don’t know about reliability though. We will have to see. 2002 Avalanche 5.3

The media could not be loaded. I got a 2002 Chevy Avalanche with a 5.3L and 200k miles, previous owner said the knick sensors were replaced with AC delco in the factory position and the CEL never went away. I ordered these and instead of taking the whole intake manifold off I relocated them to outside the block. It took less than 20 minutes and it has been working PERFECTLY!! Along with these to sensors I also ordered a harness screwed them in to the factory threaded holes on the block (they're the same size) disconnected the factory harness and ran the new harness to the sensors. Cleared the code and reved the engine to about 4k RPM for 15-20 seconds so the ECU can learn the new knock sensors and I haven't had a problem since! Its been a month and still no CEL! Just make sure you OHM out the sensors with a meter before you install them, you should get about 99-100 OHMS... TRUST ME RELOCATE YOUR KNOCK SENSORS!!

I have a work truck that I bought used from a farmer's coop. A bad knock sensor was one of the problems. Unfortunately, the knock sensor is in the middle of GM's Gen IV V8 smallblock. This wouldn't be so bad if the factory had actually sealed the area around the knock sensor. But the Canadian plant did not and allowed any water that ended up under the hood to pool over the knock sensors. The obvious result? It rusts and stops working which throws up the check engine light. And you have to take off the intake manifold to get at it. When you go through that much effort, and don't know if it works until everything is put back into place, you don't want any possible problems. So you want things like having both sensors being uniform and from the same company so the computer doesn't get messed up. But when I ordered two (there are two in every engine), I recieved two knock sensors made from different companies in different boxes. Only one was delphi, the other was an off brand. It ended up working, but it is not the situation I wanted to be in.

Water gets in these and ruins the sensor and rusts out the ground. Make a moat with grey RTV to guide watershed Clean up flat plate in the hole where the sensor screws into with a dremel. That is where the sensor gets its ground. Clean the hell out of that hole if it looks anything like mine. Grey rtv the covers on and get a new wire section for that as well as an intake gasket while you’re in there. Remove the rear foam piece from the intake to allow water to flow off to the rear.
