The "Service Engine Soon" light on a 2004 Mitsubishi Endeavor can be triggered by various issues, including problems with the engine's emissions system, a faulty oxygen sensor, a loose or damaged gas cap, or issues with the ignition system. It may also indicate a need for routine maintenance, such as an oil change or air filter replacement. To determine the exact cause, it's best to have the vehicle scanned for diagnostic trouble codes. Addressing the underlying issue promptly can help prevent more serious engine problems.

The Service Engine or Check Engine light comes on when the ECU has detected a problem with the emissions system. Do not ignore this light even if the engine seems to be running fine. Failure to repair this can cause damage to the catalytic converter especially if the vehicle is not running good or using excess fuel.
In a 2006 Mitsubishi Endeavor, the spark plugs are located on the engine, accessible by removing the engine cover and the ignition coils. The Endeavor is equipped with a V6 engine, so there are six spark plugs, one for each cylinder. Each spark plug is situated on the top of the engine, connected to the ignition coil, which needs to be removed to access the plugs for replacement or inspection.
The power steering pump is located(looking at engine from front of car) on the bottom of the engine on the left side.

To reset the "Service Engine Soon" light on a 2004 Mitsubishi Endeavor, you can use an OBD-II scanner to clear the trouble codes that triggered the light. Alternatively, you can disconnect the negative battery terminal for about 15 minutes, which will reset the vehicle's computer and turn off the light.
