That might reset it. If you have a code reader. It should have a clear code function. Other than that, if the problem is fixed. It will reset after a number of drive cycles.However, how does one “reset” the codes? Is it as “simple” as disconnecting one’s negative battery cable for 10-15 minutes? I have a 2004 ST XLT 6cyl 4.0 l engine. Thank you for response.
