Hello,

Okay, there are three ways for the Malfunction Indicator Lamp (MIL) or "check engine" lamp to go off. The first, and most preferred method, is to clear it with a scan tool once repairs have been made. The second is to have three consecutive drive cycles where the conditions that set the Direct Trouble Code (DTC) are similar and no DTC sets, or you can disconnect the negative battery terminal for at least 5 minutes, and this will wipe out the Keep Alive Memory (KAM) in your vehicle's Power-train Control Module (PCM), where the DTC's are stored.
I have included the advanced diagnostics for this DTC from the vehicle manufacturer in the diagrams down below to give you a reference so you could better understand what was going on. Please get back to us with what you decide to do and how it turns out.

Thanks,
Alex
