When the yellow TC light in a car is illuminated, it indicates a malfunction in the traction control system. Below is relevant information about the TC light: Meaning of the TC light: The TC light stands for the Traction Control system. When the ABS (Anti-lock Braking System) detects that certain wheels are slipping, it applies braking to those wheels to prevent loss of traction on the slipping wheels. Causes for the TC light to illuminate: Faulty solenoid valve; Dirty engine oil clogging the solenoid valve filter; Wear and tear on the actuator gear and impeller leading to oil pressure leakage and triggering the warning; Dirty throttle body with an opening reaching 20%, causing the engine computer to mistakenly diagnose a TC fault.
