What Causes Traction Control Failure?
1 Answers
Main reasons for the traction control light illuminating on the car dashboard: Fuel Injection Volume: Fuel system malfunctions leading to reduced fuel injection volume, such as clogged fuel injectors, low fuel pressure, or impurities in gasoline. Air Measurement: Inaccurate air measurement causing a discrepancy between detected and actual air intake volume. If the detected air intake is lower than actual, the PCM-calculated fuel injection volume will be less than required, resulting in excessively lean oxygen sensor feedback signals. The PCM then increases fuel injection, raising the positive fuel trim value. Signals: Inaccurate closed-loop feedback signals, such as faulty oxygen sensors.
