Cadillac Repair: set codes, what do these mean?, throttle position sensor, mass air flow

Question
I have several codes showing up on my 97 STS.  P0122,P0102,P1122, and P0300.  What is causing all these codes to show up together?  I have replaced the MAF, the IAC valve, the TPS.  What else is there?  Any help would greatly be appreciated.  Thanks

Answer
P0122 = Open sensor signal in the throttle position sensor (TPS).

P0102 = Mass air flow (MAF) sensor signal to high.

P1122 = Intermittent low signal in the TPS.

P0300 = Misfire diagnostic.


After you replaced all these parts did you CLEAR (erase) ALL the codes from the computer via the climate control panel ?.

NOTE: Disconnecting the battery will NOT clear the codes.
