Why in the world would you cut off the connector on the engine side? I sure hope you kept it. I did mine with just cutting the sensor side and used a screw type taplock. 5min was done

This worked for me after changing out my knock sensors twice. Easier way to do it tho. Just snip behind the connector coming from the sensors, strip and twist them together, crimp one female terminal on them both. Second, strip each wire coming from sensors and crimp in male plugs. This way if you are not sure which one is working you can switch it in seconds. Clear codes and go. My truck got it fuel mileage and timing back. Drives so much better!

Man I could use your help right now. My sensors are under my Van. Can I just run a wire from bank 1 and tap into bank 2. Bank one is bad on mine

@@gregallen8151 yes I have seen others do just that. As long as one good one is sending the signal it should work fine. Just go to oriellys or a parts store and clear codes after.

What does this mean? My truck has been running extremely rough and it’s because one of the knock sensors are bad and I don’t know which one it is. Can you help me understand your comment more clearly man?

@IxcharleyxI 10 ай бұрын

If your truck is running extremely rough, it is likely that your engine is actually knocking and the sensors are just telling you it's knocking @trevorstacey6603

now after cutting both plug halves you can never install new sensors without the plugs. you never have to cut out the plugs. all you have to do is cut the bad sensor wire 2 inches down the taped section then attach loose wire to the good sensor wire. you can use twisted wire with wirenuts and tape them off.

Thank you very interesting fix!! I have a friend with a Kia Soul (has only 1 knock sensor, a nd it is a good one it is new), he keeps getting a P0326 fault claiming it is the knock sensor. How does one 'bypass' when you only have 1 knock sensor? Thanks in advance!

The intake gaskets take 30 min to do on those. Those gaskets Leak so much there are problem solver gaskets to fix the issue. The knock sensors rust in the cavity that cause the problem.

@xxMaxMoneyxx Жыл бұрын

I don’t disagree with you about the time or the gaskets. Truth be told, most modern cars/trucks have there knock sensors on the outside. The idea of having 2 inside of a motor is insane. You can literally slam the tailgate or a door while testing the resistance of a knock sensor with a multimeter and it’ll change the reading. 250$ for a GM knock sensor kit is insane. One knock sensor reading shouldn’t be an issue.

Do NOT do this.... Buy genuine AC Delco sensors and wiring harness...replace. If still shows code check wiring to ECM.

Who hacks up their wiring harness and honestly believe they fixed anything.
