Where is the V3 Yue Ling odometer sensor? Masters, I need professional answers.

V3 Yue Ling odometer sensor location: one end is on the gearbox and the other end is under the instrument, which should be odometer steel wire. You can see outside the firewall.

The odometer sensor is actually the speed sensor we often say, which is usually installed next to the output shaft of the gearbox. The main function is to detect the speed of electronically controlled vehicles, and the control computer uses this input signal to control the idle speed of the engine, the locking of the torque converter of the automatic transmission, the shifting of the automatic transmission, the opening and closing of the engine cooling fan and the cruise constant speed.

Nowadays, many cars don't have odometer sensors, but use ABS computer signals, which are actually ABS sensors on each wheel. The new Yue Ling has no separate speed sensor, and the speed signal is the ABS sensor signal of the right front wheel.

Main types of ABS sensors

1, linear wheel speed sensor The linear wheel speed sensor is mainly composed of a permanent magnet, a polar shaft, an induction coil and a gear ring. During the rotation of the gear ring, the magnetic flux inside the induction coil alternately changes to generate induced electromotive force, and this signal is input to the ABS electronic control unit through the cable at the end of the induction coil. When the rotating speed of the gear ring changes, the frequency of the induced electromotive force also changes.

2. Ring wheel speed sensor The ring wheel speed sensor is mainly composed of permanent magnet, induction coil and gear ring. A permanent magnet consists of several pairs of magnetic poles. During the rotation of the gear ring, the magnetic flux inside the induction coil changes alternately, resulting in induced electromotive force, which is input to the ABS electronic control unit through the cable at the end of the induction coil. When the rotating speed of the gear ring changes, the frequency of the induced electromotive force also changes.

3. Hall wheel speed sensor. When the gear rotates, the density of magnetic lines passing through the Hall element changes, which causes the change of Hall voltage, and the Hall element will output a quasi-sine wave voltage of millivolt (mV) level. This signal also needs to be converted into standard pulse voltage by electronic circuit.
