To read codes, you need the proper scan tool. On 1996 and newer vehicles you will be working with OBD II, and the connectors are all the same.

AutoZone and most parts store chains will read your codes FREE. All you have to do is ask!

Knowing the code is a great starting point but not the cure.

Parts or components should not be replaced with reference to only a DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

For example, if a DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

So to avoid unpredictable hazards when fixing a vehicle based on it’s DTC codes — make sure you get a reliable OBD2 reader that’ll thoroughly scan the vehicle for faults beyond traditional DTC codes.

After you’ve properly diagnosed and fixed the problem that triggered the OBD trouble code, you can reset or clear the Check Engine a number of different ways:

  • You can just drive it and after a certain number of driving cycles it will just clear by itself.
  • Disconnect your battery, turn on the headlight switch for about five to ten minutes, and re-connect the battery. This is pretty simple, but will likely result in you losing your radio presets and perhaps some other small things like that.
  • Most if not all scan tools have an option to clear or reset codes without the use of any tools or touching the battery.
