Low pressure fuel psi reading 0?
Hi, have had a 335xi for a couple months and from the beginning had code “29F3 - DME : fuel low pressure sensor, electric”, since then I have replaced both low pressure fuel pump and low pressure fuel sensor and code has yet to go away.
After replacing low pressure fuel sensor, the data logs are reading the psi as 0 however the car is running fine, help?? data log https://datazap.me/u/zachl04/log-169...og=0&data=3-22 Last edited by Zachl04; 10-25-2023 at 12:38 AM.. |

Zachl04, what sensor did you end up using? I just went through some low side fuel pressure issues and a new sensor fixed it, though I used the upgraded sensor and adapter from FCP. Did you ensure the sensor was connected properly? There's a very short wire where one end connects to the sensor and the other end plugs into the distribution block underneath the throttle body. I'd suggest inspecting that wire; test for continuity, check that the wires aren't broken and that the pins are in the connector, and check that it's properly plugged into the sensor and the distribution block. |
