Code P0191

Got the check engine light on the way home this morning. Anyone know what the code P0191 is and should I just clear it or take it in to dealer ? Truck is all stock never chipped.

FWIW, I had the same code shortly after getting my 05.
The dealer replaced the sensor under warrenty.
Havent had any probs since.

There is a TSB flash for this problem, tho it might be a bad sensor.

Just had mine fixed with a flash. No further problems.

about 12,000 miles on the clock.

Mine was fixed by the dealer clearing the code and ordering a sensor.
Short time later, I took it in for service and they replaced the sensor.
No prob since.
Truck has 49,000 on it.
