The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
The EML (Engine Management Light) warning light on a 2002 Mini Cooper indicates a potential issue with the engine management system. This could be related to various factors such as the fuel system, ignition system, or emissions control components. It's advisable to have the vehicle's diagnostic codes read to identify the specific problem and address it promptly to prevent further damage.
The 2002 Pathfinder oxygen sensors are critical part of the engine management system. You can find the oxygen sensors in the exhaust system.

Indicative of problem with engine emission system
were is the engine management technology at on your engie

The light is one because there is a problem with the emissions system. Once the problem is corrected the service tech will reset the light.
In a 2002 Toyota Highlander, the check engine light is not controlled by a specific fuse; instead, it's part of the vehicle's onboard diagnostics system. However, if you're looking for the fuse box, it is typically located under the dashboard on the driver's side and under the hood in the engine compartment. You can check the fuses related to the engine management system, which may impact the check engine light, but there's no dedicated "check engine fuse." Always refer to the owner's manual for specific fuse locations and functions.

Yes, a faulty oxygen sensor can trigger the engine management light in a 2002 Toyota Corolla. The oxygen sensor monitors the exhaust gases to help manage fuel mixture and emissions. If it malfunctions, the engine control unit (ECU) detects the issue and activates the check engine light to alert the driver. It's advisable to have the sensor checked and replaced if necessary to ensure optimal engine performance and emissions compliance.
It is reset with a OBD2 scan tool, after the repair of the system.
