How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons.
• If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
• If your vehicle's Check Engine light was lit, but went out without any action on your part, OBD II will still have a recorded fault.
Your vehicle may pass or fail, depending on the inspection practices in your area.
• If you had recent service that required disconnecting the battery, OBD II diagnostic information may be incomplete and "not ready" for inspection. A vehicle that is not ready may fail inspection.
