Why does My Car Say Service Engine Soon

Checking your car’s service engine soon light might seem like a simple task, but there are actually a few things you can check to rule out potential problems. In this article, we’ll walk you through the different things you can check and why they might indicate a problem with your car’s engine.

What is the Service Engine Soon light and why does it come on?

The Service Engine Soon light typically comes on when there is a problem with your car’s engine. The light usually means that there is something wrong with the engine and it needs to be fixed as soon as possible.

What can you do to fix the problem?

If your car says Service Engine Soon (most common code is P0174), there are a few things you can do to try and fix the issue. Some simple fixes can be fixed while you’re at the dealer, while others may require more extensive work.

The most common issues with Service Engine Soon codes are related to either the airbag sensor or the fuel injectors. If one of these components is faulty, it can cause the car to think it needs to service its engine. In many cases, simply fixing one of these problems will resolve the issue and your car will stop saying Service Engine Soon.

If that doesn’t work, your next step would be to take the car in for a diagnostic check. A mechanic can scan the engine for any errors and may be able to pinpoint the root cause of the problem. If that doesn’t work, your car may need a new component or may need to be completely replaced.

How often does the Service Engine Soon light come on and for how long?

The Service Engine Soon light (or “SES light”) is a warning light that typically comes on when the engine is not performing at its best. The light can stay on for a short time or for a long time, depending on the severity of the issue. In general, the SES light will come on whenever there is an issue with one or more of the car’s engines.

How to clear the Service Engine Soon Light code

If your car is displaying the “Service Engine Soon” light, there are a few things you can do to try and clear the code. One option is to take your car to a mechanic and have them check the engine, but this might not be necessary if the code is only coming on intermittently. In some cases, simply restarting your car may clear the code.

How to reset your car’s computer

If your car says Service Engine Soon, there is a good chance you can reset the computer. Resetting the computer will help fix any issues that may be causing the warning light to come on. Here’s how to do it:

1. Park your car in a safe place. You don’t want to risk damaging your car while trying to reset the computer.

2. Turn off the car and remove all of the keys.

3. Disconnect all of the cables near the engine (except for the battery).

4. Reconnect all of the cables except for the battery and turn on the car.

5. Hold down both the brake pedal and the gas pedal at the same time while turning on the ignition. The car will start moving, but you should keep holding down both pedals until it stalls out (about 10 seconds). This will reset the computer.


If you’re experiencing issues with your car, it’s probably a good idea to take it in for service. However, if the service engine soon light is on and you’ve tried all of the fixes recommended by your mechanic, there might be another issue at play. In this article, we’ll cover some of the reasons why the Service Engine Soon light might be on and what you can do to troubleshoot and fix the problem.
