The easier fix would be to just connect both the green and blue wire together and disconnect the wire to the bad sensor. In your case if both sensors go bad just connect both the green and blue wire to your one new sensor. no need for 2 sensors. The ECM reads the sensors seperate so you can trick the computer to think both sensors are connected by connecting both wires to the same sensor. At least that's what I've been told.I just conneted both my wires to the same sensor today and cleared the codes. So far so good.

Cool advice, by the way before you bypassed the sensors did your truck have a loud whirring noise & loss of power? On my hummer h2 this seems to be the issue & also when I hit the brake while the truck is parked the noise gets louder. Now it appears to be some oil leaking from front bumper on passenger side which I'm more concerned about now if that's what it is. I'm hoping it's just a busted hose or something simple. Not sure what it all means but hopefully I can make the fix. Any insight would be gladly appreciated thanks👍😁💪😎💪

Yes it looks like a small radiator that's mounted in front of the actual coolant radiator in front of the truck on the drivers side it sits at the top and is easy to access. My cooler was in such bad shape I had to cut it off where the hoses connect to it. The rust wouldn't allow me to simply unscrew the two hoses attached to it with a wrench. After I cut it off I went to Auto zone and bought a one foot of coolant hose for like two dollars and simply reconnected the hose lines I cut when taking the cooler off. I put two small clamps on it and it's ready now no problem at all.👍😎👌

I was having the same problem with my 05 Yukon Denali 6.0 Vortec. Thanks to your video I was able to relocate the knock sensor to the passenger side of the block. Now at 1st it wouldn’t just screw in on a cold block but, in my opinion after I ran the engine for a little while the block heated up and that made the knock sensor easy to screw in to the already drilled out bolt pattern. Honestly I just hand tightened the sensor, and ran wire from the sensor back to the connector, spliced & connected those wires and Walla Check Engine Soon Light GONE! Its been over 2 weeks now with no problems 😎

I did this on my 03’ Silverado 6.0 on 4-12-19. Both my sensors are bad, so I was working on putting my 2nd sensor where you suggested with the temp sensor. Well, it’s a coolant sensor, so that didn’t work. I looked for a long while, and couldn’t find another spot, so I did what I really didn’t want to do, I put both wire feeds from the computer on to one sensor, by just using the older harness, and splicing them to 1 wire, and put the sensor on the passenger side of the motor. I know it’s more ideal to have 2 sensors, but my thought, is if you keep everything else working right, you shouldn’t have issues, and I am not. I have an idea for possibly getting a sensor on the other side, but I won’t be doing that anytime soon.

Resetting the modules A is a great idea for older vehicles anyway makes the computer re learn values from older sensors. Then it figures out how to run right offer those values which may be slightly different than a brand new sensor or when the sensor was put in.

where did you put the second knock sensor

caleb patt The second knock sensor is still in the stock location. It hasn't thrown a code so i just left it where it was. Typically only one sensor throws a code. But if the second one throws a code i will install it on the driver side cylinder head.

Not simple to do its a pain in the ass and tedious. However idk what the one moved reads to come up with a conclusion if this is a valid repair. Back in the 80s they started with knock sensors but they were all mounted on the outside of the blocks but there wasn't a ECU like today to read values.

Not being derogatory but the proper fix takes an hour total with basic hand tools. Looks like you put in more time and effort for the " bypass". It's not the smartest design by gm but it's not rocket science either.

It easy unless water gets in the pockets and rust the sensor to hell. Ask me how I know, please come over and yank this thing out. I've been a back yard mechanic for a long time. Everything is easy when it's easy. When it's not it's a pain.

Don't, just please don't do this. Replace the sensors and harness once and don't hack your vehicle. All you need to do is to add some silicone around the caps to seal them off from any moisture and you're golden. This repair doesn't cost a hundred, so not sure how you can save hundreds either.

Great idea I just replaced my intake manifold gaskets on my 5.3 litre as they were leaking I was told to replace the knock sensors at the same time with genuine parts keep in mind there was nothing wrong with the old ones I also replaced the wiring harness did the silicone dam update the new gaskets fixed the problem but a week later thru a code for bank 1 knock sensor I refuse to tear it down again I going to do this great idea of your does it just screw in or did you have to tap it
