Is the Navigation System's Speed Limit Alert Accurate?

Navigation system alerts are not always accurate. The navigation system requires regular updates, and if not updated in time, discrepancies may occur, leading to inaccurate alerts. Additionally, some road sections may have their speed limits altered, but if the updated data is not promptly uploaded to the satellite, it can also result in inaccurate navigation alerts. Additional Information: The car navigation system, also known as the in-vehicle GPS navigation system, uses its built-in GPS antenna to receive data from at least three of the 24 GPS satellites orbiting the Earth. By combining this with the electronic maps stored in the vehicle's navigation device, it matches the position coordinates determined by GPS satellite signals to pinpoint the car's exact location on the electronic map.

What are the symptoms of a faulty car idle valve?

Symptoms of a faulty car idle valve: 1. Engine shaking; 2. A strong gasoline smell when the car is warm, and the idle speed becomes unstable, fluctuating between high and low. Excessive idle speed increases fuel consumption, and higher idle speeds also lead to greater emissions of CO and HC, thereby increasing vehicle exhaust emissions. The idle valve is installed on the throttle bypass air hole. The idle controller, based on the ignition signal, controls the air intake during engine idling. When the engine idle load increases, the ECU controls the idle control valve to increase the air intake, thereby raising the idle speed to prevent unstable engine speed or stalling. When the engine idle load decreases, the ECU controls the idle control valve to reduce the air intake, thereby lowering the idle speed to prevent excessively high idle speeds.
