So, we are just powering on our new system. We updated the software to 9.41 and have been setting things up. All seems good expect the Oil pressure is a red-X. I tested the transducer using the fuel pressure plug and the transducer seems to work. I tested the voltage at the oil pressure plug and it is 7 Volts??? I tested the fuel pressure plug it is exactly 5 volts. I could have pinned it wrong but the 7 volts I don't understand. My pin out shows J243 19- 5V 12- GND and 17- Signal Wire. My Transducer is GMN-01179.

I had the same problem. In my case the settings for the oil pressure instrument had been deleted in the 9:41 software.
After inserting the range setting again it works as before.

Good luck

I appreciate the help, I tried this and still oil pressure is red X. You can see where the parameters are set but it is Red Xs.

I assume the G3X (GEA24B) is powered before engine start. Mine is not.
I suggest you pull the breaker (power) to the GEA24B before engine start.
With the engine running, reset the breaker.
If this works you may have a problem with an electric spike in the system during engine start.
The starter takes a lot of amps (+200). When the starter stops, voltage increases with a sharp spike (ms).
This can have an affect on low voltage transmitters.
A zener diode can catch voltage spikes of short durations. It´s installed on the bus between +14V and GND.

If the red X is there before engine start the problem is not related to a voltage spike.

Good luck

I had one pin in the wrong spot. Corrected it and all is good now.
