Greetings everyone,
I'm having some repeat issues with the knock sensors on my 2005 Yukon XL Denali. I've change both sensors with AC Delco sensors and a genuine GM harness, all torque specs were adhered to and mating surfaces cleaned. I also make sure to disconnect the positive battery cable and ground it to clear the memory. I have now done this 3 times over the last 6 months or so and get either 1 or both knock sensor codes shortly after changing them, the most recent time the codes posted the next day. I would like to not have to pull the intake off anymore, so any thing else I should look at would be greatly appreciated.
