If you have your car’s check engine light on, it’s telling you that something is wrong. When you take it to a mechanic, they will plug a diagnostic tool into your car’s computer to try to figure out what the problem is. If the mechanic can’t find any codes, it’s possible that they have been erased.
There are a few ways that this could happen. One is if you disconnect your car’s battery. This will reset all the codes in your car’s computer. Another way is if you use a code reader or scanner that has a “clear codes” function. This will also erase the codes.
If the mechanic says that your codes have been erased, it’s possible that the problem has been fixed. If the light is still on, it means that the problem is still there and the mechanic will need to figure out what it is.
