Having an OBD2 scan tool is useful in many situations when an engine light comes on.
But what if you don’t have an OBDII scan tool and need to know the code?
Many vehicles have a built-in diagnostic that will give the code, as I recently found out with Dodge cars and trucks.
I have not tried this on all Dodge cars and trucks, but it certainly worked for me on a 2001 Dakota, and many others have stated this method has worked for them.
The steps are easy, with the key simply needing to be cycled on and off three times.
How To Read Dodge Check Engine Light Without a Code Reader
- Cycle the Key from OFF to ON three times.
- The last cycle, the key should be in the ON position.
- It will give the code in the odometer LCD window on the dashboard.
- The code will show for only a moment and flash P-done before going back to normal.
- If you miss the code since it does flash quickly simply repeat the steps.
If you do not have an OBDII scan tool and want to know what the error code error number is, the above method works on many dodges.
Once you have the code, Google the code number along with the Dodge make/model, and the problem with your car or truck can be found.
The code will point to a specific problem the vehicle is having and show what needs to be fixed.
Reading through forums on the vehicle year and the code can be very beneficial and help fix the issue.
Another free method to get an OBDII scan is to take it to an auto parts store since many will do a scan for free.
Hopefully, this helps if you have a Dodge and don’t have an OBDII scan tool to see what the code is.
