Audi Q7 P0087: Fuel Rail/System Pressure → Too Low ...
20200430· Before doing anything, check to see if your Q7 has a fuel pressure test port at the fuel rail or in the fuel line. You’ll need to look up the fuel pressure specs for your engine and model year. If the fuel pressure is ok, you probably have a bad fuel pressure sensor (or the fuel pump has a bad wiring connection). If there isn’t enough pressure, you could have an issue with the pump, or ...
Fuel Pressure Sensor how to test? | Ford Focus Forum
20100730· 2,690 Posts. 5 · Jul 29, 2010. I can read Ford specific PID''s. I was reading/logging Fuel Rail Pressure, no FMEM (not sure what FMEM is though) and Raw Fuel Rail Pressure Signal, no FMEM (this is the output voltage of the sensor, basically what the ECU sees and translates to a pressure). Neither one did what I thought it should vs applied vacuum.
