P0325-knock Sensor 1 Circuit
I just bought an 08 Charger and have an extended warranty. It runs like a champ. This code will throw and I notice no difference in performance. After three drive cycles the code clears itself and the MIL goes off. Took it to dealer twice, first time code was just reset. Second time light had come on and cleared itself but I took it back anyways. Mechanics took it for a few days, drove it and could not get the code to throw. Discovered the AC clutch was cycling and was low on freon, so added freon and said let them know if it comes on. 30 mins after leaving dealer it came on again, same code. drove all weekend and code cleared itself. Code came on again this afternoon, I did three more drive cycles and the code is cleared again. This is after finding out I wasn't able to drop the car off tonight. So I am at a loss. I'm thinking faulty sensor or maybe adjustment due to altitude, possibly. I bought in Colorado Springs, carfax says its a Florida car. Mechanic is reluctant to dig unless the light is on, but it clears before I can get it to them. Any thoughts? Thanks
