What does code P1650 mean?

Q: What does code P1650 mean?

Power Steering Pressure Switch Out Of Range Fault. P1650 on a Mazda means the power steering pressure switch is reporting a voltage outside its expected range, so the engine computer cannot reliably tell when the steering system is under load. The computer sets this code when the switch signal stays high or low longer than the programmed window, which affects idle speed compensation and can trigger the warning light.
