CAT Forklift Code E-31

I have a CAT S/N - A183F36127 & M/N - 2C6000. I've ran into an issue where the forklift with operate fine until it throws "E-31" and goes into a limp mode. Lift runs at half of normal operating speed. I've inspected wires to see if any were broken or loose, none were found. I have left work for the day and will be back again tomorrow. Any advice or opinions on what else to look at. I have a "Trouble Diagnosis" stack of papers, I will go through tomorrow. Any advice will help greatly, thank you in advance!

ouch
that's the throttle control. last one i did, spent forever doing all tests and installing a new throttle control. Didn't work!! it could be a short , open, or internal binding of electric throttle motor.
mine ended up being rotten wires ALL over the harness. everything i touched broke in pieces.
Start at fuse box area, left and right kick panels. Fix anything corroded. I ended up also replacing the fuel pressure sensor plug at TB
It's notorious for bad connections.
BTW< there is an OBD2 connector under the cup holder. You can clear codes easily with cheap scan tool, set to "Mitsubishi"
Throttles can fail...but installing one and finding out the harness is bad really....you know what

Por favor....put email in profile...you might get a code list ;)

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. 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.
