I was driving home from work the this past week, and as I was topping a hill on the freeway the dashboard lit up with some ominous error messages about my engine.

Next, the check engine light came on. I was able to get home without issues, but I was assuming that I would need to bring the car in to get it fixed. Before I went too far, however, I went online to do some research on the specific issue my car was having. Some others had mentioned that some relatively cheap fixes for the problem, but they suggested checking the OBDII fault code that caused my check engine light to come on.

If it was the same code, it might be worth it to try and fix it on my own. While I was online diagnosing the problem, I came across some articles that told how you could just read the OBD-II codes yourself, and figure out what type of a problem you have. Often the fault codes will lead to relatively minor issues like a loose gas cap, or may point you in the direction of your car needing service with a certified mechanic.

Before I made an appointment I decided to get my car scanned to find out what the fault codes were that were causing the light to come on. If it was this same issue that I had seen online I might be able to fix the car myself and save myself hundreds of dollars.

The light could be an indication that there is a serious problem like a major engine issue that could be a safety issue , or it could be something simple like tightening your gas cap which my wife had to do one time.

So get it checked. Here I am checking the engine fault code recently using a Bluetooth dongle and my Android smartphone:. So what are the most common reasons the check engine lights come on? AutoTrader gives the 5 most common reasons:. All light-duty vehicles less than 8, pounds sold since in the United States have on-board diagnostic systems OBD-II — on board diagnostics version 2 that diagnose when your vehicle has certain power-train, emission and other readings that are out of accepted ranges.

Once the scanner is connected it will read a PID code that can then be used to help diagnose what your issue might be. Once you have the PID you can go online and see what the code means. For example, Wikipedia has a listing of PID codes you can check out. When trying to find out what tripped your check engine light, there are quite a few ways that you can check what the trouble code is.

Some of the ways will even be free. Why do they do that? Seems like a good idea on their part. Your best bet is to just find a local auto parts store and give them a call- and verify if they will do a scan for free. Be careful, however, because if it is a vague issue you can quickly spend more on parts trying to fix an issues, than if you had just gone to a mechanic in the first place.

You can quite easily check what your PID fault codes are yourself. Once you get the PID code from whatever device you use, just look it up online to see what your issue could possibly be related to. Your local mechanic may do a scan for you free of charge, especially if you already have a relationship with them. I have a good local mechanic that I use when repairs are needed, and they have checked codes for me free of charge on occasion.

They do have to charge for their time. To get more detailed diagnostics, or to get repairs that are covered by warranty you may have to go to a dealership. Dealerships will often have more expensive diagnostic equipment that has better and more regularly updated software, so they can often get you some of the best information. I have never, however, gotten them to give me a free diagnostic of what the problem might be.

Again, they have to charge for their time, so if it is a more advanced issues you may have to pay. For me I think getting one of free scans at your local auto parts store is probably a good first step to take. It can give you some insight into the problem, and hopefully give you an idea if you need to pursue professional help. So I went into my local Advance Auto Parts store and they did a quick scan, free of charge.

They found that the fault codes on the on board diagnostics system were all related to when my battery died a couple of weeks ago. They reset the codes and the check engine light went out.

They advised me to keep an eye on things over the next few days and weeks, and if it came on again to bring it back in. They can recheck it then and see if there were any other unrelated issues causing the light to come on. After getting it checked at the auto parts store again, it turns out there was a throttle control sensor that was having problems.

Are there times that you would rather just bring it in and pay? The new Credit Sesame credit score app is a great way to stay on top of your credit while on the go. It allows you…. I was reading the news this morning when I came across this little news item talking about some of Barack Obama's campaign promises he made….

Peter Anderson is a Christian, husband to his beautiful wife Maria, and father to his 2 children. He loves reading and writing about personal finance, and also enjoys a good board game every now and again. You can find out more about him on the about page.

Don't forget to say hi on Pinterest , Twitter or Facebook! This article is great! I also had a similar experience with my check engine light and also am on a tight budget as a full time student. While trying to find a parts store near me that offers free services, I came across a site that shows the nearest auto parts locations to you based on GPS that offer free check engine light diagnostics.

Check it out today:. Awesome post Peter! As an employee of Advance Auto Parts I just want to inform folks that the company is going to stop reading engine codes and referring those who come in for that once free service to one of our commercial customers, in other words a garage.

This has already started and will pretty much be a done deal by the end of June A few, and I mean a VERY few of these shops have said they would do the code reads for a nominal fee. Advance and other stores like them were started mainly for the DIY, er but some local shops are complaining that they are losing business by us offering this free service.

I think the decision to stop providing this service is going to backfire on the company in a few ways. They customer will either take that code and go home and google it and come back to Advance or another DIY store and buy the part or stay at the shop. The shop will then call one of these stores and order the part like a gas cap and the customer, who was just sent to the shop,since we now will not read their code ,will watch as one of our delivery vehicles pulls up and brings the part they would have bought from us to that shop and marks up the price.

For larger more complicated issues I understand the reasoning for going to a professional but like I stated earlier Places like Advance, Auto Zone etc were started for folks who wanted to avoid paying a garage for something they may be able to fix themselves. I guess now that Advance has bought up most of their competition they feel there is more money to be made selling to the commercial shop than the DIY customer.

I think this will blow up in their faces and will lose more business than they realize. I for one expect to see many pissed off customers and I will refer them to our corporate office. I was shocked when a friend of mine went to Advance Auto Parts and was turned away after asking to have her engine light read. Instead, they should let the customer use the scanner themselves.

I agree, this will backfire into the face of corporation. I used to work for Advance. For example, most of your late model vehicles and up have over 30 different OBD codes that indicate an oxygen sensor problem.

Pulling codes is only the first step to a successful diagnostic. Well said Adam Hunsicker! This advice is like telling someone with a toothache to get some dental tools and a mirror and fix it themselves.

A small leak could be a gas cap or it could be a small crack in your fuel tank. A misfire could be a spark plug. Not the OE Design… but the actual brand. Yes, every car has a recommended brand. A misfire could be a coil. Oh what could it be??? Or stop playing with something you are clearly not trained to do and let the professionals do their job.

If you come to the shop and ask me to put in new spark plugs, I will do as you ask. I make it clear that it might not solve your problem. If you decline, I will make sure to note that on the paper you sign. Turns out the misfire was a bad fuel injector…. God help someone that has a hybrid or electric car.

This blog could easily kill them…. It is one thing to be an informed consumer. If you want to learn about cars, go to a real school. Invest the hundreds of thousands of dollars that most technicians have invested in their education, tools and continued training.

God forbid we make an actual living. The bigger the job, the LESS the shop makes. Top it off with the way we are treated by our customers…. Let one more customer throw their keys at me and order up an oil change. Karin Burton, I agree with you whole heartedly. I have improved my income, just in time for out of pocket expenses and grocery prices to go up, and absorb anything extra I thought I was going to have due to the increase in income.

Now, if shops like the ones Joann and Adam work at want to provide the Diagnostic for free, and the customer knows they can TRUST what the mechanic is telling them is the issue, and that they will fix it for the price quoted and guarantee the person will pass emissions, then I would just bypass the DIY and go straight there.

Unfortunately, shops do not have a good reputation for being honest and trustworthy, and friendly. I have been using a home used corolla for a year.
