  1. I'm working on an 05 legacy gt turbo. I recently replaced the clutch but after starting it up and attempting to relearn the tps I was unable to. I tried both the manual way by disconnecting the battery then letting it idle yadayada. I also tried via scan tool. Neither would take. It's throwing a p0123 code. It was throwing an o2 sensor code also, but it has aftermarket exhaust system that deleted the o2 sensors and the resistor tricking the ecm had fallen out, I replaced it and the o2 sensor code went away. Reading the position sensor, it reads that the tp is at 100% when idle and no foot on the accelerator and it chugs, push the accelerator to the floor and it idles normally. The accelerator pedal position senators are reading seamingly normal and changes normally when the accelerator pedal is pushed to different spots, voltages are within normal parameters. I also pulled the throttle control motor relay out from behind the dash and it is still good. I swapped a throttle body out of known well running legacy, same problem. The tps angle percentage is reading 100% no matter what. Sub throttle sensor voltage is steady at 1.7 v and main throttle sensor steady at 5v. The other issue I see is the throttle motor duty % is at 0 and does not change and throttle motor voltage is showing 0 and these don't change at all whether the accelerator is being pushed or not. I can't find any pinched wires or damaged connections and I'm losing my mind over this thing it's been here for months. Could the o2 sensor be causing this somehow?? Any insight or help would be much appreciated.
