VEHICLE FAULT CODE FIRST DETECTED TYPE
97 SPN-520207 June 23, 2020 12:16 Intermittent


Also sometimes, when starting it's like the starter misses or bad connection. I checked I battery post but where the problem is I don't know.

The SPN you provided isn’t good.

There is a SPN # and FMI #. Without both of them, have no idea what the actual fault code is, please check and repost.

Check ALL terminal connections, batteries AND starter. Make sure they’re all clean and tight. Im not an expert here but it sounds like a bad connection. A loose connection can cause this problem and or cause it to not even start at all. A loose and wet connection same thing.

Isn't type 97 some auxiliary system? Like vorad or lane mitigation or abs?

No clue

Never seen that code, and can't find anything about it.

water in fuel sensor issue. The water-in-fuel sensor in the fuel water separator. Likely wiring, sensor itself, or actually water int he fuel form poor quality fuel at truckstop.

One other possibility too. The problem I experienced once upon a time and it was caused by fuel injector cups allowing water into my fuel.
