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.

DTC 522135-3 - TISS Speed Sensor Out of Range High/Open (TCU)
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.

The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
