Rail Pressure Sensor code 3F30

335dFan · 11-22-2013, 07:39 AM

The other day I heard this "bong" and I figured the little D computer was trying to tell me something. No indicator lights. I delayed a bit reading the code, so now I can't remember what was going on when I heard the bong, but I suspect it was associated with my re-installing the JBD. In my lack of attention to detail, as I recall I forgot to put the car to sleep before separating the OEM connectors and installing the JBD cables. Bet that's what caused the 3F30 code. Whatcha think?

since you didnt put it asleep this makes sense. The DDE is still awake so when you disconnect the sensor it definitely is going to interpret that as a sensor issue. Might as well clear and see if it comes back
