Q
how long after resetting check engine light before emissions test

After resetting a car's check engine light, it's wise to wait at least one complete drive cycle before undergoing an emissions test. A typical drive cycle varies depending on the car's make and model but generally means driving a car in a variety of conditions (highway, stop-and-go traffic, etc.) over a period of, on average, 50 to 100 miles. This allows the car's onboard computer systems to run and complete all self-diagnostic checks. Prematurely undergoing an emissions test after resetting the check engine light may result in failure because the car's computer system might not have completed all tests, leading to an incomplete readiness status. Depending on your vehicle and how it's driven, achieving a complete drive cycle could take a few days.

It is recommended to drive the vehicle approximately 100 to 200 miles before the emissions test after resetting the check engine light. This gives the vehicle's computer enough time to perform any self-diagnostic checks. The exact mileage may vary depending on the vehicle's make and model.
