I will describe 1 sensor related to some automotive problems. This sensor rarely fails, but if it does, it’s a censor that can cause quite a lot of trouble. It doesn’t fail itself, but if there is a cable break or a sensor failure in the sensors and systems associated with it, the codes related to this sensor are released. Before I talk about this censorship, I want to talk about Yawing Movement first. Yawing refers to the circular motion of the car centered around the Z Body Axis. Especially used in airplanes.
There are also situations where the car spins when the wheel slips. This is the loss of stability of the car. Yawing Movement is a circular motion centered on the center of the car (usually around the handbrake). The yaw rate sensor installed in the car is a type of gyroscopic device that measures the angle between the direction the car is heading and the direction the car is actually moving. That is defined as Slip Angle.
The Yaw Rate Sensor is a small electrical circuit that is placed inside the car’s ECU (or under the car’s dashboard). The Yaw Rate Sensor, which is made to be used as Fri as the car is old, rarely fails. Most of the problems are caused by failure of other sensors related to the Yaw Rate Sensor. If there is a problem with the Yaw Rate Sensor, the Engine Warning Light, ABS Warning Light, etc. will light up. Also, when checking with the Scan Tool, codes like U0123 often appear.
The yaw rate sensor measures degrees per second. For example, if the car turns 90 degrees in 2 seconds, the yaw rate sensor will show 45 degrees per second. The easiest test is to put the Yaw Rate Sensor in your hand and turn it around. If the scan tool shows that the degree has changed, the sensor is good. Usually, the problem of Yaw Rate Sensor is communication fault. There are many problems caused by the failure of the bus line connecting the yaw rate sensor and other sensors. So, if codes related to the Yaw Rate Sensor come out, a Bus Line Check should be done.
Whether it’s the car’s ECU (or Skid Control ECU), etc. Brake, speed sensor, deceleration sensor, etc. It is necessary to reset or initialize the yaw rate sensor when the sensors related to the lower part of the car fall. If not, VSC lights and TRC lights are on. The way to do it is to enter the ABS Menu. Select Clear Raw Rate (or) Zero Point Calibration. There will be 3 steps. It will do it automatically. I just choose OK. There is one. You need to put the shift lever in the P position with the IG on. If the warning light still does not disappear even after zero point calibration, you will need to clear it again from the Mode Change menu in the ABS menu.
Enter Mode Change, Just keep clicking OK and Yes. While doing so, the warning lights should be blinking. If not, you have to start over. C1234 Yaw rate sensor malfunction This code is mainly related to the car’s braking system. Meaning, the yaw rate sensor is faulty. Why – There is a CAN Bus line that connects this sensor to the car’s Skid Control ECU. If the voltage on this CAN Bus line is higher or lower than it should be, the Skid Control ECU will display these codes.
The skid control ECU of the car takes the signal sent from the yaw rate sensor and controls the stability of the car. to prevent the car from overturning, This Yaw Rate Sensor is used to make the car go out of the way. Yawing is measured. It is also explained in the picture. To fix the fault you need a good multimeter and a diagnostic tester with troubleshooting instructions. Roughly speaking. Check the wires. Censors must be installed to check whether the pattern is correct or not.
