While Toyota has its VSC system, Honda has its VSA (Vehicle Stability Assist). They're both stability control and traction control-type programs designed to ensure that your car doesn't lose traction. If the VSA system is faulty, it would cost you anywhere from just $150 to over $1,500 to fix it. Ultimately, it depends on what triggered the VSA system to malfunction in the first place. For example, replacing a bad brake switch will set you back $150. Meanwhile, a brand-new speed sensor will cost you roughly $200 to $250. Otherwise, a worn-out yaw rate sensor - not commonly replaced - might cost you up to $700. Worst comes to worst, you'll have to replace the entire VSA module for $1,500.
