How Can I Check The Diagnostic Trouble Codes On My Nissan Altima When The 2012 Nissan Altima Check Engine Light is on?
If your 2012 Nissan Altima check engine light is on, the first thing you should do is have it checked by a trusted mechanic. A trip to the auto parts store or a misdiagnosis could cause more problems for your car and money for you. If there’s one or more error codes in your 2012 Nissan Altima check engine light and it’s been steadily on for a day, contact your local dealer and schedule an appointment.
If you want to do it yourself , you’ll need to go to a local auto parts store and purchase a code reader. The cost of this device can vary, but it’s usually between $25 and $50. This device, which looks like a small computer, will read the error codes from your car’s computer and tell you what’s wrong with it. It should come with instructions on how to use it, but here are some basic steps:
- Turn off your car’s engine.
- Locate the check engine light on your dashboard (if you don’t know where it is, ask someone who has driven a car before).
- Connect the code reader to this socket by plugging it in and pressing one of the buttons on it.
- Turn on the reader, wait for it to recognize your car’s make and model.
- Press the button on the reader that says “scan” or “read codes” (this will tell you what error codes are stored in your car’s computer).
- Once you have read the error codes, turn off your car and disconnect the reader.
How Much Should It Cost To Repair The 2012 Nissan Altima Check Engine Light?
