Any body seen this before? {throttle position sensor insufficient activity}
What does that mean?
I was cruising down 295 with cruise control on. Noticed that it was surging
abit and then cruise dropped out and code came up.

The code is actually "tps does not agree with map" the most common problem is the tps sensor, however the map sensor could be at fault too. there are also a couple other things than can cause this code. it could be a wiring issue or a bad pcm.

Thanks for the info. I erased the code. I'll see if it returns. The truck runs fine.
