EMS-2 and VDO fuel pressure sensor
Posted: Wed Apr 30, 2025 12:08 am
I have an EMS-2 with an RDAC XF. I haven’t been able to get my fuel pressure sensor to work. It’s a VDO type sensor 0-100 psi and 10 bar. The reading on the EMS-2 shows 999psi. It’s a single wire sensor and I have the body of the sensor grounded to a grounding block that is connected directly to the engine block. I have a VDO oil pressure sensor that is wired the same way and it is working fine.
My EMS-2 analog channel settings are as follows:
Channel 1 oil temp (lead in screen reads “OIL TEMP SETUP”)
Channel 2 oil pressure (lead in screen reads “OIL PRESS SETUP”)
Channel 3 fuel pressure (lead in screen reads “ANALOG CH 3 SETUP”)
Does the fact that Channel 3 doesn’t read “FUEL PRESS SETUP” mean that there is a problem?
At this point I don’t know what to look for, so any suggestions would be greatly appreciated.
