I am assuming you have a GM LPG. Fuel pressure in the rail is too high. Check your pressure - should be 12 psi - key on/eng off and 4-6 psi @ idle. Anything other than that, replace regulator.

It is the transmisson input speed sensor. It is a three wire sensor on the trans valve. Most of the time it will either be a sensor, or if someone steam cleaned it, it will set the code.

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
