The code P0327 is knock sensor circuit performance low input I will need the last eight of your vin number to get you the trouble tree for that one. The P1635 is a short to power on one of the 5 volt referance circuits.I posted the info for that again if you get me the last 8 of the vin number I can see if the bulletine I found for the P1635 is for your car.
