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.

I only need the last 8 of the vin it should be 1Z followed by 6 more numbers.

Ok your vin is 1Z311211 so the bulletine for code P1635 doesnt apply to your car.I posted the trouble tree for the code P0327 so now you have both trouble trees for both codes so let me know what you find.Remember you post all replies on this question do not start a new question to reply to this one.
