Troubleshooting EP Error on Firestone Air Command F3 Compressor Remote
Updated 07/21/2024 | Published 11/29/2021 >
Question:
Error code is displayed on wireless remote EP
asked by: Adam R
Expert Reply:
According to the instructions under F3 Remote Error Codes, EP on your remote means you have a bad pressure sensor. Underneath EP will show L for left air spring, R for right air spring, or in this case T which means you have a bad pressure sensor in the tank.
I reached out to Firestone and in order to fix this they suggest you disconnect the air lines, turn the key on, and let the compressor vent to the atmosphere for approximately 25 seconds. Then, reconnect and retest.

I have the EP T code on my remote but I don’t have a tank installed. The compressor sets there and pulsates non stop when I first start my truck . I turn truck off and then back on and it works perfectly . I have to start my truck twice every time for it to work properly.
