Q: What does code P1692 mean?

Turbo Control Solenoid Circuit. P1692 on Mazda vehicles indicates that the powertrain control module (PCM) has detected an electrical fault in the turbo control solenoid circuit, which manages boost pressure by controlling the wastegate or variable turbine geometry actuator. The PCM monitors the solenoid's command and feedback circuits and sets this code when the expected current or voltage is outside the normal range, often resulting in reduced turbo performance.
