Symptoms of odometer sensor broken, does the odometer sensor broken affect the throttle?

mileageThe meter sensor is also called the speed sensor, which is usually installed next to the output shaft of the gearbox. It is mainly used to detect the speed of the electronically controlled car tires and send the detected signals to the ECU to control the shifting and cruise speed of the automatic transmission. The principle is to sense the number of turns of the tire through the sensor on the differential or the half shaft, because the angular velocity of the half shaft and the wheel are equal, the radius of the tire is known, and the mileage can be calculated directly through the history parameters.What are the symptoms of a broken odometer sensor? Will it affect the throttle? Let's get to know it together.

Symptoms of broken odometer sensor

Failure or damage of the odometer sensor will generally not affect the throttle. The car will lose the speed information, which will have a certain impact on the car's performance. For automatic gears, it will affect the car's shifting; for manual gears, the car's odometer and tachometer will stop.

Odometer sensor detection method

Method 1: Remove the connecting plug of the vehicle speed sensor and check the resistance value of the two leads of the sensor with the resistance file of a multimeter.

Method 2: Rotate the output shaft of the transmission, and use a car oscilloscope to detect the signal voltage waveform between the two leads of the vehicle speed sensor, which is an alternating current waveform, and the amplitude and frequency of the waveform increase with the speed of the output shaft, which indicates that the sensor has good performance .
