Where is the abs sensor and how much voltage is the abs sensor plug

absSensors are an important part of the abs system. Abs can maintain the directional stability of the car during braking, shorten the braking time and braking distance of the car, and can effectively prevent the car from locking and locking during emergency braking. The situation of out-of-control sideslip increases the handling of the car and makes driving safer.

absWhere is the sensor

The abs sensor is generally located at the position of the tire close to the bearing.Wheel hubThe outside of the bearing, the inner ring of the brake disc, each wheel has. The function of the abs sensor is to monitor the speed of the vehicle. The abs sensor outputs a set of quasi-sinusoidal alternating current signals through the action of the ring gear that rotates with the wheels. The frequency and amplitude are related to the wheel speed. The output signal will be transmitted to the ABS electronic control. oneYuanInside the ECU, real-time monitoring of wheel speed can be realized.

absHow much voltage is the sensor plug

Generally, the input voltage of the abs sensor plug is 5-8v, and the output voltage is 650-850mv. In the actual measurement, because the electronic stability control module N47/5 has a fault protection function, the voltage cannot be maintained continuously after the ABS sensor plug is unplugged, so the voltage data cannot be used as the judgment standard. The correct measurement method is to observe the voltage value status displayed by the multimeter at the moment the ignition switch is turned on. As long as the voltage value changes, the line connection is normal.
