Although this may be considered a common Ford DTC, it's very minor. You in fact can safely ignore this code and it should go away as part of normal driving, you do not need to clear this code (as it may not actually turn off the MIL). If you want to the code to clear itself, faster, run through the Ford Drive Cycle. However, if you have other trouble codes, the MIL will stay on as there are other issues.
Hope this helps.
