Our 2008 Yukon 6.2L had a P0333 bank 2 knock sensor high voltage. I purchased genuine GM Knock sensors and had my mechanic replace both sensors. He cleared the codes. Two days and a few miles later the code came back. I have an Innova 5160RS scan tool and have cleared it twice more. Any ideas? Thanks!

Have you measured the voltage at the sensor and compared it to the specification? You may have a shorted component that for example may be feeding the sensor 12V when it should be 5V.
