P0207 OBD2 Fault Persistent on 2018 RAM 1500 - How to Fix?

Model: RAM 2018 Fault Code: P0207 Posted: 2025-11-09 06:36

Hello, I'm experiencing a persistent OBD2 fault code P0207 on my 2018 RAM 1500. When I drive aggressively, additional codes appear: P0307, P0175, and P0300. I can clear all these codes except for the permanent P0207. I previously had this issue six months ago. I've already replaced the fuel injectors, spark plugs, and ignition coils. Compression tests showed no issues. After removing the battery and recharging it for five days, I fully reinstalled all components—no symptoms or codes appeared at that time. Now, after the vehicle's battery drops below 11.9V (at idle), the P0207 code returns. I've replaced the battery with a new one, but the problem persists. Even after disconnecting the battery for four days, the issue remains unchanged. I’ve also tested the vehicle on GPL fuel—still experiencing the same fault. Anyone have experience with this specific P0207 error on a 2018 RAM 15 or know how to diagnose and fix it? Any help would be greatly appreciated! Thanks in advance.
