Q: Code P0503.
I have a car that just got it's exhaust changed back to stock and just changed rear brake pads. I now have code P0503-speed sensor. Car starts fine, but when shifting it makes a clunky noise, but clutch is brand new. Car also feels jerky when I let off accelerator. Acceleration also has a slight lag when pushed down that I have never had. Could this all be just from the speed sensor? Also getting abs, psm, driver assist failures and a check engine light. Do I need a reflash, new sensor, new transmission sensor, or something else? All electronics work fine, windows work fine, and headlights are fine. Could you point me in the right direction. Thanks in advance!
