Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection: Oil Pressure Light For vehicles with an oil pressure light, if there is a problem with the oil, the light may stay on after the engine is started, or comes on while driving. • The vehicle will not pass this inspection if the check engine light is on with the engine running, or if the key is in ON/RUN and the light is not on. • The vehicle will not pass this inspection if the OBD II (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if the battery has recently been replaced or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer/retailer can prepare the vehicle for inspection. This light indicates that oil is not going through the engine quickly enough to keep it lubricated. The engine could be low on oil or could have some other oil problem. Have the vehicle serviced by your dealer/retailer. The oil light could also come on in the following situations: • The light comes on briefly when the ignition is turned on to show that it is working properly. If it does not come on with the ignition on, there may be a problem with the fuse or bulb. Have the vehicle serviced by your dealer/retailer. • Sometimes when the engine is idling at a stop, a chime sounds and the light may blink on and off. This is normal. 3-42
