2011 Tundra check engine light

I am a Toyota tundra owner of a 2011 model that now has 234000 miles on it and still feels new. But today the check engine light came on! No observable engine stutters or missing, etc. But the light stays on. Is this serious? Can I drive it to the dealership--its a 30 mile drive

 

If the check engine light is staying on steady, and not flashing, with no noticable performance issues, there should be no problem driving it 30 miles. As for severity, only reading the code(s) can say for sure, could be anything from the gas cap not sealing to a bad O2 sensor to an air pump failure. No point speculating or worrying.

 

Hiya and welcome from SoCalif!!!

 

go to auto zone and have them read the code...probably an O2 sensor or the MAF sensor.

 

Welcome from Ohio!

 

That mileage and year, probably O2 sensors or Catylytic converters

 

Well I went to Oreilly's and scanned my truck. I had 5 codes but Po441 and Po455 were duplicated, I checked my Gas cap, and it was loose! I am going to try to wipe out the codes and see if they come back..
Thanks for the help.
