CEL on. 6 codes!!!

  

mitrals -> CEL on. 6 codes!!! (1/13/2008 5:17:42 AM)

I bought a 2001 Hyundai XG300 with a CEL light, and I got the following codes:

P0446 (vacuum building up in the fuel tank/evaporative system)
P0715 (Input/Turbine Speed Sensor Circuit Malfunction)
P1110 (ETS malfunction),
P0120 (throttle position sensor (TPS) A circuit problem)
P1174 (Electronic Throttle System #1 Close Malfunction)
P0302 (Misfire in cylinder 2), I am not worried about this as I intend to do a tuneup on the car.

I dont want to go all out replacing everything. How should I go about it. Is there a pattern here?Any help is appreciated.

p0446 is emission related, p0715 is input speed sensor you have to replace that, after the tune up then erase the DTCs. normally p0120,p1110,p1174 is comes on because of the rest of codes that you retrieved. sometimes the ETS goes bad and you have to replace it though.

Did a tune up (Just 6 plugs), air filter, oil change. Threw in some Lucas in the engine, some in the tranny, fuel injector cleaner. Filled up the gas, tightened the cap reset the light, and just made a 500 mile round trip no CEL light yet. So might be the gas cap. Thanks for the help.The XG was royally abused by the previous owner!!!
