Hello I will help you with your question,
It is likely that there are no codes stored. The check engine light will be turned on when it is time to change the oxygen sensor. There are two connectors under the dash on the left end that one hangs free while the other is connected. You swap from one connector to the other and the light is reset for another 60,000 miles. If the light comes on after removing battery power but the truck runs fairly normally the connectors need to be swapped.
Let me know if this is the case I can tell you how to pull codes but you will not lose any if you disconnect the battery as any codes will set again when you start the engine. The codes are on a one at a time basis. You pull a code, repair the problem, disconnect the battery and if another or the same code sets again you work on that
Let me know what I can do to help you with this
