When the check engine soon comes on it doesn't point to a specific problem ,it telling you that there is an issue with something that is effecting the overall performance of your truck,without you even noticing any difference in performance. best thing to do is to have a diognostic check done on your truck and that will produce a specific code that will point to the problem an take the guess work out of it .you can even buy a code scanner and do it yourself sometime its a pretty easy fix.

Illuminates when the ignition is switched on. It should extinguish as soon as
the engine starts.
If it illuminates with the engine running, it indicates a malfunction with the engine management system. Have this checked as soon as possible.
If it flashes when driving, reduce the vehicle speed immediately until the light illuminates constantly. If it continues to flash, avoid heavy acceleration and high engine speed, stop the vehicle and have it checked immediately.
On some vehicles this light may be red - again stop the vehicle and seek assistance.
If it is safe to do so, try stopping the vehicle, switching off the engine, wait two minutes, then restarting the engine to reset the engine management system.
With the light illuminated, the vehicle is still safe to drive as long as no other faults are apparent with the engine. Have the vehicle checked by a dealer or garage as soon as possible to avoid any damage being caused to the catalytic converter
