To reset the maintenance light on a 2012 Toyota Prius C, first turn the ignition to the "ON" position without starting the engine. Press the odometer button until the odometer display shows "Trip A." Then, turn the ignition off. While holding the odometer button, turn the ignition back to "ON" and continue holding the button until the maintenance light blinks and then turns off. Release the button, and the maintenance light should be reset.

The metal plate in a distributor's cam sensor rotates through grooves to create a varying magnetic field. This motion generates electrical signals corresponding to the engine's position and speed. These signals are then sent to the ignition system, helping to time the firing of the spark plugs for optimal engine performance. Essentially, it plays a crucial role in engine timing and efficiency.

To replace the vehicle speed sensor (VSS) in a 2000 Toyota Sienna, start by locating the sensor, which is typically found on the transmission. Disconnect the negative battery cable and remove any components obstructing access to the sensor, such as the air intake duct. Unplug the electrical connector from the VSS, remove the mounting bolt, and carefully pull the sensor out. Install the new sensor by reversing the removal steps, ensuring a secure connection and proper alignment.

The O2 sensor on a Mazda 929 is typically located in the exhaust system. For most models, you will find one or more sensors positioned either before or after the catalytic converter.

Critical speed of a shaft refers to the rotational speed at which the system's natural frequency coincides with the shaft’s rotational frequency, leading to resonance. At this speed, vibrations can increase significantly, potentially causing mechanical failure or excessive wear. It's crucial in engineering to avoid operating machinery at or near this speed to ensure stability and longevity. Engineers often calculate critical speed to design shafts that operate safely and efficiently within specified limits.
