You have 2 knock sensors. They keep your engine from knocking which is important on these cars. By sensing knocks from lower octane gas the car will adjust its timing. Without it the engine can be damaged. Reset the code, then use highest octane gas and see if you get the same code. If so, then you should consider changing the knock sensor. Both are right under the intake manifold, so that will have to come off. You'll need the sensors (I'd change both while you're in there), and an intake manifold gasket. www.fcpgroton.com has all of these parts.
Knock sensor part number is #1270492 (same number for both).
Btw, if you are actually going to replace the knock sensor, while you have the intake manifold off, you might as well replace your pcv (positive crankcase ventilation) hoses and oil separator, which sets right in front of your knock sensors. This is great preventative maintenance. www.fcpgroton.com sells a kit to take care of all of your pcv hoses, the oil separator/trap and connecting pieces and clamps. Just a thought, and what I would do if I was getting in there anyway.
