How does OBD-II help the environment?
The intent of OBD-II systems is to ensure proper emission system operation for each and every vehicle and light truck during its lifetime by monitoring emission-related components and systems for malfunction and/or deterioration. An important aspect of OBD-II is its ability to notify the driver of a problem before the vehicle’s emissions have increased significantly. If the vehicle is taken to a repair shop in a timely fashion, it can be properly repaired before any significant emission increase occurs. OBD-II systems also provide automobile manufacturers with valuable feedback from their customers’ vehicles that can be used to improve vehicle and emission control system designs.
