Bought an 03 suburban lt. Knock sensor code came up a few days later (p0327) for bay 1. replaced both sensors and wiririmg harness. Knock sensor In bay one was clearly bad (Orange and covered in rust and was wet). This reaffirmed my suspicion of the bad knock sensor. Replaced and torqued both correctly. Created the rtv seal and replaced the gaskets woth felpro metal gasket. Still receiving a knock sensor code every other time I run the vehicle. Vehicle has 237k on body with 123k on the engine. Cleaned all the areas in and around the knock sensor. Verified no further moiture or rust was inside either housing. Before i pit the intake back on. Again the knock sensor in bay 1 was visibly abused when I pulled it out to replace it. What could be a further issue causing code p0327? Both sensors were oem acdelco.
