How to Solve Traction Control System Malfunction?
1 Answers
Here are the solutions for traction control system malfunctions: 1. Replace the fuel, fuel injectors, spark plugs, or fuel pump. Fuel system issues can reduce fuel injection volume, such as clogged injectors, low fuel pressure, or impurities in the gasoline. 2. Inspect and replace the air flow meter or oxygen sensor. Inaccurate air measurement can cause discrepancies between the detected and actual air intake. Closed-loop feedback signals may also be inaccurate, such as with faulty oxygen sensors. Below is the working principle of the traction control system: 1. The control device of the traction control system is a computer that monitors the speed of all four wheels and the steering wheel angle. When the car accelerates, if the computer detects a significant speed difference between the drive wheels and non-drive wheels, it immediately determines that the driving force is excessive and sends a signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing wheel slip. 2. The computer uses the steering wheel angle sensor to understand the driver's steering intentions. By monitoring the speed difference between the left and right wheels via wheel speed sensors, it determines whether the car's steering degree matches the driver's intentions. 3. If the computer detects understeer (or oversteer), it immediately determines that the driving force on the drive wheels is excessive and sends a command to reduce the driving force to align with the driver's steering intentions.
