Hey needs info on check gage light....

[valdezbertha]

I have a check Gage light that came on after the spark plugs and spark plug cables were changed. Once those were changed it came on. Set for about an hour and then did not turn back on. Motor turns over. I know that a check Gage light means it has to do with oil pressure, fuel or temp of engine. I know that there is no leakage coming from the coolant, oil, or fuel. All three are full. What test can I do in order to rule out the oil,fuel, or temp on the truck so that I can find out which part is the problem?

You may want to have the code scanned to see what it's pointing to.
