Introduction to the Traction Fault in the Orlando?
2 Answers
Traction fault refers to a situation where the transmission system of wheeled vehicles such as cars, railway locomotives, bicycles, etc., fails to generate sufficient torque to rotate the wheels. The main reasons for the traction control light on the car dashboard being illuminated are: 1. Fuel injection volume: Faults in the fuel system causing reduced fuel injection, such as clogged injectors, low fuel pressure, or impurities in the gasoline. 2. Air measurement: Inaccurate air measurement leading to a discrepancy between the detected intake air volume and the actual intake air volume. If the detected intake air volume is lower than the actual intake air volume, the PCM-calculated fuel injection volume will be less than the actual demand, resulting in an overly lean signal from the oxygen sensor, prompting the PCM to increase the fuel injection volume and causing a positive fuel adjustment value to rise. 3. Signal: Inaccurate closed-loop feedback signals, such as a faulty oxygen sensor.
As someone who repairs cars year-round, I've found that the traction control malfunction in the Wolando primarily occurs on slippery roads or during rapid acceleration, where the system automatically limits engine power to prevent wheel spin. If the warning light comes on, nine times out of ten it's due to a dirty or failed wheel speed sensor, as these sensors are overly sensitive and can trigger false alarms when encountering mud or dust. Sometimes it's just a software glitch in the computer module, which can be resolved with an update. I always remind owners not to ignore this issue, as it can make the vehicle prone to losing control during turns, especially on lightly rainy days, which is the most dangerous scenario. When diagnosing, you need to use a diagnostic tool to read the fault codes to check if it's due to loose wiring harness connectors. In most cases, simply cleaning the sensor will do the trick, saving both time and money. The best prevention method is to have the shop thoroughly inspect the chassis and electronic systems during regular maintenance—don't wait until problems arise. Safety always comes first.
