Maintenance and Specifications permitted to intentionally remove an emission control device or prevent it from working. Information about your vehicle's emission system is on the Vehicle Emission Control Information Decal located on or near the engine. This decal identifies engine displacement and gives some tune up specifications. Please consult your Warranty Guide for complete emission warranty information. On board diagnostics (OBD-II) Your vehicle is equipped with a computer that monitors the engine's emission control system. This system is commonly known as the On Board Diagnostics System (OBD-II). This OBD-II system protects the environment by ensuring that your vehicle continues to meet government emission standards. The OBD-II system also assists the service technician in properly servicing your vehicle. When the Check engine light illuminates, the OBD-II system has detected a malfunction. Temporary malfunctions may cause your Check engine light to illuminate. Examples are: 1. The vehicle has run out of fuel. (The engine may misfire or run poorly.) 2. Poor fuel quality or water in the fuel. 3. The fuel cap may not have been securely tightened. In which case, the fuel filler cap light will also be illuminated. These temporary malfunctions can be corrected by filling the fuel tank with good quality fuel and/or properly tightening the fuel cap. After three driving cycles without these or any other temporary malfunctions present, the Check engine light should turn off. (A driving cycle consists of a cold engine startup followed by mixed city/highway driving.) No additional vehicle service is required. If the Check engine light remains on, have your vehicle serviced at the first available opportunity. Readiness for Inspection/Maintenance (I/M) testing In some localities, it may be a legal requirement to pass an I/M test of the on-board diagnostics system. If your Check engine/Service engine soon light is on, refer to the description in the Warning lights and chimes section of the Instrument Cluster chapter. Your vehicle may not pass the I/M test with the Check engine/Service engine soon light on. If the vehicle's powertrain system or its battery has just been serviced, the on-board diagnostics system is reset to a "not ready for I/M test" 223 2005 Ranger (ran) Owners Guide (post-2002-fmt) USA (fus)
