I have a non-Toyota specific question about electronic oil pressure senders. I have a project at my house where I need to measure 0-100PSI with real-time updates sent to my computer. I've been looking around and most of the pressure sensors out there are industrial and cost many hundreds of dollars. I realized that oil pressure senders have the range I need, and they're much cheaper. The problem is that I don't know what the output signal looks like. Most industrial sensors report a current between 4 and 20 mA proportional to the pressure. Does anyone know what the standard is in oil pressure senders? As long as I know what type of signal it sends to a guage, I can have my computer read that signal.

Thanks!
