I have been complaining lately that my truck felt sluggish and got worse on gas, but other than that everything seemed fine. I wrote it off to the winter blend gasolines. I just got a scangauge for christmas and installed it (It's awesome). The bad news is that I came up with a code of P0325. I know that code means something is wrong with the knock sensor circuitry, but to replace the sensor I am looking at about $1000 (according to research)and I'm not happy. Are there any other causes that would trigger a code? Would a knock that occurs with a good sensor trigger a code? The truck is a 2000 3.3 with only 42,000 miles on it and it was garage kept since new (no rat damage to wires). What should I try before giving it to the dealer to get raped? Can it be a bad distributor cap and rotor?, wires? plugs? dirty fuel filter? dirty injectors? or is it only a bad knock sensor that would trigger a P0325 code? Thanks in advance, please help!!!
