A “check engine” light may be coming on in your car, and it might not mean anything. Your car’s computer might just be warning you that there are problems with one or more of the engine’s parts, and it’s up to you to take action. In this article, we’ll explain what a “check engine” light means and what you can do to fix it.
The Definition of a Check Engine Light
A check engine light is a warning light that comes on in some cars when the engine fails to pass a test. The warning light might indicate that there is something wrong with the car’s engine, such as an oil leak, or a broken part. If you see a check engine light on your car, you should take it to a mechanic to have it checked out.
What the Check Engine Light means
When your car’s Check Engine light comes on, it means there is a problem with one of its engine components. Depending on the severity of the issue, you may need to take your car to a mechanic to have it fixed. Here’s a look at what each of the seven Check Engine light codes mean, and what they might mean if your car is blowing smoke or sounding off warnings:
1) P0455 – This code indicates that there is an air/fuel mixture problem. It could be caused by a plugged air filter, poor fuel economy, or a clogged fuel injector.
2) P0456 – This code indicates that there is an oxygen sensor problem. If the sensor isn’t getting enough oxygen, it can cause the engine to run poorly and produce high levels of emissions.
3) P0459 – This code indicates that there is a problem with the vehicle’s emissions control system. If this code is coming up frequently, it may be indicative of a larger issue with the car’s emission control system.
4) P0460 – This code means that there is a problem with one of your car’s spark plugs. A bad spark plug can cause misfires and reduced power.
How to Fix a Check Engine Light
If you have a check engine light on your dashboard and you’re not sure what it means, read on for some tips on how to fix it. First, make sure the light is actually on. If it’s not, don’t worry yet; we’ll get to that. Second, determine the code that’s showing. There are six codes that can show up on a check engine light: P0171, P0271, P0272, P0273, P0274, and P0275. The first three are typically related to emissions problems, while the last three are related to problems with the engine itself. Here’s a breakdown of each code:
P0171 – This code indicates that there may be an issue with the air/fuel mixture in your car. This can be caused by something as simple as a clogged air filter or incorrect fuel levels. In most cases, just removing the clog and refilling the filter will fix the problem and return the code to “normal.” If this doesn’t work, there may be more serious issues involved and you’ll need to take your car in for repairs.
P0271 – This code is typically associated with a bad catalytic converter.
What to do if the Check Engine Light comes on Again
If you’re like most drivers, you’ve probably been through this experience at least once. You’re driving along, enjoying the scenery and music, when all of a sudden your car’s Check Engine light comes on. The reason for the light could be anything from a simple problem with your air filter to a more serious issue with your engine. Here are some things to do if the Check Engine light comes on again:
1. Drive to the nearest mechanic and have them take a look at your car. Even if you don’t think there’s anything wrong, it’s always best to be safe and have someone look at it firsthand.
2. If you can’t take your car to the mechanic, try to find an auto parts store that carries replacement parts for your model of car. This way, you can at least get help diagnosing the problem without having to spend a lot of money on repairs that may not be necessary.
3. If all else fails, call a tow truck and have your car towed to a mechanic or an auto parts store. Sometimes problems that seem minor can turn out to be more complicated than first thought, and having access to professional assistance can save you a lot of time
