Good afternoon everyone!!
I wanted to ask everyone for help with these solenoids that I am getting code p01105 and it seems to be (Fuel Pressure Up Solenoid) and I gave direct current to the solenoids and they make a sound and I think they are working and then with the current meter the outputs current it seems that they do not have current, does anyone know how much voltage it has to have and does anyone know the diagram for these solenoids to know where the lines get the current from!!
Thank you in advance 🙏

Www.charm.li for the factory service manual

The solenoid receives voltage directly from the ECU, its a 5v reference signal (Actually battery voltage). I believe it only sends the voltage out on a hot start, but I could be wrong.

The sensor triggers the check engine light when resistance in the sensor is too high, or the sensor is unplugged. If the sensor is plugged in and triggers a check engine light then the sensor is bad, At least that's how I remember reading the diagnostic flow chart

For the replacement sensor eBay the part number on the sensor itself to find results. If you google the actual part number it wont have any results as the part is discontinued and rarely available.
