Steady Engine light but no code

I have a 2014 Nissan Frontier SV 4X4 with just under 30K miles and have never had an issue with it.

The engine light has now come on and is steady. Everything seems to be fine. All instruments are normal. No engine noises or misfires.
I've verified that the gas cap is in correctly.
I plugged my OBD II code reader in and there are no codes showing. I've since driven a few local trips, with stops and starts... hoping that the whatever caused the engine light to come on would reset and turn off the engine light... but so far it hasn't.

I do all my own general maintenance and have a good working knowledge of engines and I don't abuse my cars and trucks.

I really don't want to go to the dealer... and want to avoid that... if I can.

Any suggestions on how to proceed?

Have you tried to get the code manually?

Is that not what I was doing when I plugged in my OBDII code reader?

In car ECM Diagnostics/ECM Reset procedure:

1) Sit in the driver's seat.

2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)

3) Fully depress and release the accelerator pedal five times in less than five seconds.

4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the SES light flashes.

5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.

Long flashes (0.6 seconds) indicate the first digit of the code; count the blinks one through nine and write down the first digit. (Ten blinks indicates a zero.)

The next three digits follow in turn in the same fashion except with faster blinks (0.3 second) and a 1.0-second pause between digits.

The ECM code repeats intself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard get-in-and-drive-the-car mode.

Additionally, if you get four blinks of ten (0000), the ECM is indicating no malfunction.

You can clear the code (and the annoying SES light) by holding down the accelerator pedal for more than 10 seconds while the SES light is blinking. When you release the pedal, the ECM erases the trouble code(s).

I didn't know about that way of accessing the codes. Thanks!

After doing what you advised...
I got a 0128 code which indicates a Coolant Thermostat Below Temp.
I did notice when driving that the coolant temperature indicated seemed lower than normal... but it has been cold out... so didn't I didn't link that to my engine light coming on.
My assumption now is... that I my thermostat is probably stuck open and should be replaced, which is something that I can do.
Sound good?

You're welcome. Only one way to find out for sure.

The real question is....What's wrong with your OBDII reader?

seems odd for a thermostat to go out that soon.

I'm sure that will be it... I'll replace the thermostat tomorrow and if it doesn't reset the code and turn off the SES.. I'll clear the code myself.

Again... I really appreciate your help and I learned something new.

Any idea of why my OBDII code reader didn't give me this code when I plugged it in?

I personally would have cleared the code right after reading it and see if it pops up again before replacing anything.
