    We would need a little more info, to be able to try to help you.

    What year truck?
    Have you had the codes pulled?

    42,000 is very low mileage for C or K truck. What model truck is this?

    If you go to a local Autozone, PartsAmerica/Advance, VIP Auto... they will be able to help you pull the codes.

    Could be something as simple as an O2 sensor. Any issues with the engine, transmission lately?

    'Check Engine' light and 'Service Engine Soon' light are the same thing. It is not a maintanance thing. The computer is sensing that there is something wrong. You need to get an OBD (On-Board Diagnostic) scanner to see what the problem is. For 96 and UP it is OBDII for 95 and lower it's OBDI.
