Exhaust gas recirculation valve fault
fault code 16 is: Air thermistor. Looks for signal less than 0.1 or more than 4.9 volts
does the light illuminate during start up? If not the lamp is burned out. If it does, then the engine computer is likely at fault.
1-Disconect Battery for a few minutes 2- Reconnect Battery 3- Turn key to on position 4- Let computer check your engine 5- Start your engine
The computer has detected a fault with one of the electronic components and is warning you to run a diagnostic test.
First step is to have it checked for trouble codes. If the check engine light is on, the pcm has detected a fault and set a code.

Code 41 Throttle position circuit fault
For the 1994, you have to remove the negative battery cable, then depress the brake and hold it in for 5 seconds to reset the check engine light.
Is this a v6 engine? Does it occur only under load (in gear, wors if you power brake lightly)? If the answer to these questions is yes, it is an ignition fault, probably the wires but check for worn plugs or weak coils also.
you likely mean "check engine" which could be a multitude of reasons,you need to plug it into a reader to desipher the code Many parts stores will read the codes for you for free and depending on the fault you can get the parts there to do the job.
Use a code reader to find out why the check engine light is on.
If the check engine light is on, use a code scanner to find out why.
