Daewoo Nexia car speed sensor

21.07.2022 /

Modern South Korean cars are equipped with gearbox controllers. The first of them observes the speed of rotation of the input shaft, and the other - the output. The data is transmitted to the Daewoo Nexia speed sensor. There, the information is processed to calculate the current engine load, as well as to select the most appropriate mode.

Features

The Daewoo Nexia speed sensor is located in the gearbox. When rotating, the output shaft generates a certain number of pulses depending on the number of revolutions of the rotor. This indicator is proportional to the linear speed of the car.

On some models of the Korean manufacturer, information is transmitted to the on-board computer, which may cause the anti-skid system to work incorrectly. You can fix the problem yourself and contact the service center. Ignoring damage is fraught with serious consequences and can lead to costly repairs.

Malfunctions

The Daewoo Nexia speed sensor may not work due to mechanical damage or problems with cables or contacts. Malfunctions can be diagnosed by the absence or incorrect readings of the odometer, speedometer and tachometer.

The first sign of a problem with this device is that the HOLD or A/T indicator on the instrument panel comes on from time to time. Typical breakdowns also include:

  • 0 km / h on the speedometer, despite the fact that the car is in motion all the time (one of the key symptoms);
  • interruption of the brake clutch when performing slow maneuvers;
  • abnormal acceleration of the car;
  • contact oxidation;
  • activation of emergency mode.

Please note that damage to the device will result in no display of the actual speed and calculation of the distance traveled. If this happens, you should immediately visit a car service for diagnostics.

Replacement

For inspection and repair, it is recommended to visit a car service. If you have the necessary skills, you can replace the spare part yourself, observing the safety regulations, since in some cases it will be necessary to disconnect the battery and the air filter housing.

If the intake and exhaust ports are a little rusty, try cleaning them. In some cases, this helps to extend the life of the device. Before buying, you need to consider the complete set of the engine. Speed ​​sensors are sold for Daewoo Nexia 8-valve and 16-valve powertrain.
