Q: Code for pressure solenoid D

The P2716 code is produced when the ECM has detected that the throttle body actuator motor has failed to read the correct position at which the butterfly valve within the throttle body should be in order to produce a smooth idle for the engine. C1201 relates to the vehicle stability control system and can be triggered for many reasons such as malfunctioning ABS or brakes or in some cases when electronically controlled suspension is not working properly. I would recommend having an expert from YourMechanic come to your home to take a look at the vehicle anddiagnose the Check Engine Lightand possibly conduct a test drive to ensure there are no safety issues related to these codes.
