I believe all of those parts stores will do that but having a guy that sells parts and doesn't fix cars read your codes is a very bad Idea. For example, lets say you took your car to the local discount parts store and had the free code reader plugged in to find out your car has a code P0171 oxygen sensor detects a lean condition. If you want an oxygen sensor they will sell you one. But remember that is not what the trouble code said to do, it only says that a lean condition has been detected by that sensor. If someone replaced the oxygen sensor and the car had a weak fuel pump or a dirty fuel filter causing not enough fuel or maybe a vacuum leak causing to much air to enter the engine or any number of other things that could cause the engine to run lean, then the light would come right back on for the exact same reason meaning the oxygen sensor did it's job and reported the lean condition, but most people would think that the new sensor was bad or someone just doesn鈥檛 know what they are doing or worse maybe even believe they got ripped off. There is no such thing as a machine or a trouble code that tells you a part is bad or to replace a part. Trouble codes report engine conditions that are reported by sensors and the part stores are using it as a get rich quick scam. Remember that the money you save by doing it yourself will come in handy when you need it done right.
In true reality the dealer of your car has the best diagnostic equipment to solve specific codes on your on-board computer.



We had a lady who replaced her gas cap which she purchased from Auto Zone. That's what their inexpensive code reader said was was wrong. As it turned out, she had a seam leak in her gas tank. Auto Zone wouldn't return her money for the $40.00 gas tank cap even though they advised her it caused the problem.



Multi-testers which include volt meters can test batteries, alternators and starters. Anybody including you can purchase an inexpensive volt meter from Sears, Home Depot, Lowes, Radio Shack, hardware stores and electronics supply stores.I heard that a major auto parts store is now offering to pull the codes for you when your check engine light c?
Also Pep Boys will do it, You just tell them your light is on and they will check the code while you wait, usually only takes a couple of minutes.

They will tell you what the code is and you can make up your own mind as to how to go about fixing it.

If you fix your problem yourself you can go back and have it reset so the light goes off.
Or you could buy a simple code reader for about $20 and do it yourself. Like the first guy said, even if you know what the code is, that doesn't mean you know what is wrong with the vehicle.I heard that a major auto parts store is now offering to pull the codes for you when your check engine light c?
