Default Ezgo st400 48v slow

Im new to golf cart ownership but I recently bought a st400 48v with a dump body on it and i have done some work like new batteries, throttle sensor, and repaired the sepex controller. Currently the cart moves, which is more than it dis before but its only going maybe walking speed on flat ground and crawling up hill. Dump body operated fine and the charging system is working. Please help!

The LED on the controller may be blinking a fault code. List of fault codes are on pages F7 and F8 of attached service manual.

The speed controller threw a 1-3 code for the speed sensor. I replaced the speed sensor and the code is still there and the cart is still limping.
