Ok, so my 2000 passport just crapped on me. To try avoid the very long story, if you were getting a code (P1514) that said Control Module Throttle Actuator Position Preformance and a P1125 Accelerator Pedal Position System, which part would you throw at it first? A TPS (Throttle body position sensor), a throttle pedal position sensor, a (MAF)Mass Air Flow sensor, or a full throttle body assembly? At this point the only thing I know for sure that the throttle blade Actuator motor is not open or shorted to ground. And has about3.7 omhs. Any help would be great, full history available if you feel like reading a book. It did recently have intale manifold gaskets replaced. Thanks!
