The Check Engine lights is on and the power locks do not respond to remotes. The throttle position sensor has come on, however, it goes off after restarting the car.
I'm not quite sure what to make of this description, but I'm guessing you are trying to say the check engine light goes off and on intermittently with a code stored for the throttle position sensor (TPS). I do not have the wiring diagram for this vehicle handy, but I doubt the problems with the TPS has anything to do with the inoperative remotes. The TPS and its corresponding circuit will need to be diagnosed for faults. Then the power lock issue will have to be addressed separately. The door lock module, or anti-theft module, may simply need to be reprogrammed to recognize your keys. A trained technician, such as the ones at YourMechanic, will be able to help you diagnose both issues.
