It might have to be started several times for the computer to recognize it. Kind of like a fuel cap leak after it has been corrected.

Pull the battery cables off of the battery and then touch the two leads together to clear the codes from the PCM. Wait 15 minutes. hook the battery back up. codes should be reset.

Alternate method; See if there is a parts store such as Knecht's that will hook up a scanner and clear the codes.
