Today while driving I went to accelerate from a light and got a chime and a big red "ETC" warning on the instrument panel. A little red ETC warning light at the bottom of the panel also came on. The truck went into limp mode. It seemed like it was locked in second gear as it took more throttle than usual to get it moving and it wouldn't upshift once it was moving.
I drove another ~1/4 mile to my destination and parked for about 2 hours. Upon returning, I got in and it started right up. The check engine light was still on but the little red "ETC" light at the bottom of the instrument panel was now off and it drove completely normally (no longer in limp mode) for the 20 minute ride home. Full power, normal shifting, etc.
When I got home I put the scanner on it and it showed P2122 - Throttle Position Sensor Low. The red "ETC" light was still off so I decided to clear the codes and see what happens. I cleared the codes and ran it for awhile and no codes or warning lights came back on.
So, was this just a random computer glitch - or is something failing? What do I do about it if everything now reads "good"?
Truck specs in sig. Only has 16,000 miles on it!
