How to deal with the heating fault of Dongfeng Nissan Tiida oxygen sensor

Sensor troubleshooting is as follows:

1. Check whether the sensor is installed in place, if the installation is fine, replace the right rear bearing, and the general induction rotor is integrated in the bearing;

2. Use the data stream of the decoder to see if the right rear wheel sensor is not transmitting the wheel speed. If there is no wheel speed, the sensor is still broken.

The main function of ABS is to play the role of braking anti-lock, to put it bluntly, it is to force the vehicle to brake to avoid wheel locking.

When the vehicle brakes, if the wheels are locked, it is easy to skid, loss of direction and other consequences.

The heating fault of the Dongfeng Nissan Tiida oxygen sensor should be that the line has been aged, and it is recommended to replace it.

Oxygen sensor is a standard configuration on the car, it is a measurement element that uses ceramic sensitive elements to measure the oxygen potential in the exhaust pipe of the car, calculates the corresponding oxygen concentration by the principle of chemical equilibrium, and monitors and controls the combustion air-fuel ratio to ensure product quality and exhaust emission standards. Oxygen sensor is widely used in the atmosphere control of various coal combustion, oil combustion, gas combustion and other furnaces, and is the best way to measure the combustion atmosphere, with the advantages of simple structure, rapid response, easy maintenance, convenient use and accurate measurement. The use of this sensor for combustion atmosphere measurement and control can not only stabilize and improve product quality, but also shorten the production cycle and save energy.

Tiida oxygen sensor is on the exhaust pipe of the engine. After the oxygen sensor is damaged, it will lead to the poisoning of the oxygen sensor, the engine will produce a large amount of carbon deposits, the exhaust pipe of the car will emit black smoke, and the lack of power of the engine will be obviously felt in the process of driving the car, and it will also cause the heater resistance wire to burn out. The symptoms of damaged oxygen sensors are as follows:

1. If it is blocked by carbon particles, the signal voltage of the oxygen sensor will be high, and the engine computer will issue instructions to reduce the amount of fuel injection, so that the mixture is too thin; Dust and oil block the through hole between the oxygen sensor and the atmosphere, the signal voltage of the oxygen sensor will be low, and the engine voltage will indicate the injector to inject more fuel, causing the mixture to be too concentrated;

2. When the current oxygen sensor fails, the ECU cannot get the information of the oxygen concentration in the exhaust pipe, so it cannot feedback and control the concentration of the mixture, (whether there is more or less fuel injection and air intake, the ECU does not know at all) In this way, the engine fuel consumption and exhaust pollution will increase, and the engine will have unstable idling, lack of fire, surge and other fault phenomena;

3. After the oxygen failure means that the operating conditions of the three-way catalysis cannot be judged, once the three-way catalysis fails, then the exhaust gas will exceed the standard, and the fuel consumption will affect the working condition of the engine, and the heavy will affect the annual destruction of the key banquet or direct replacement of the three-way catalysis.

Transducer sensor is a detection device that can feel the measured information, and can transform the felt information into electrical signals or other required forms of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. It is the first link to realize automatic detection and automatic control.

The existence and development of sensors allow objects to have senses such as touch, taste, and smell, allowing objects to slowly become alive. It is usually divided into ten categories: thermal elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic sensitive elements, moisture-sensitive elements, acoustic components, radiation-sensitive elements, color-sensitive elements and taste-sensitive elements according to their basic sensing functions.
