Welcome to JustAnswer, my name is XXXXX XXXXX X'm here to help get your problem resolved. This code most likely means the throttle body assembly has failed. You can use some throttle body cleaner and a rag to clean it out as good as possible, reest codes, then try again. If that doesnt help replace, P1694 means "
Throttle Valve Actuator Start Test Spring Tes and Limp-Home Position Failed" Let me know if you have any questions, thanks.
so "companion mode" doesn't necessarily mean its the computer communicating with the rest of the car?
Correct, it sounds like whatever scantool you had just gave a generic definition. Let me know if you have any questions, thanks.
