Unplug your battery and turn and hold the ignition switch to start. Hold it for about 30 seconds or so. Once you plug your battery back on, your truck will be hard to start until the computer re-programs.
If you do not repair the malfunction that caused the code, the check engine light will come back on.
Usually you can just remove the battery cables from the battery for a few minutes to reset the system. I think some do require a scan tool to reset, but I don't feel this is your case. But the CEL will come back on if the problem is still present. Once the codes are cleared, the system resets and the IM monitors are reset. Meaning they will relearn after so many starts and different driving conditions. The period between the majority of the IM monitors being reset (3 out of 5 or something like that) and when the code reappears, if it is a stored fault, is the period when a vehicle can be inspected w/o the CEL being a factor.
Have vehicle scanned to determine the problem
You do not have to reset the computer after this repair. If the Check Engine Light is on it is not because you made this repair. If you disconnected the battery the computer will reset itself.
