Getting Fuel Pressure via OEM MAP Plug Issues
Hi all,
Just finished my re-wiring on my car, and all the sensors seem to work, but the OEM MAP plug adapter wires to 0-150PSI sensor harness and the ECU is not reading more then 0.04-0.07Volts fluctuating, as if the signal wires is not getting any pressure. I tested the wiring on the map sensor plug and I am getting 5.5V power, red wire, ground on black center wires and also getting ~5V on the feedback wire, which makes no sense, since the ECU is showing IMAP_ext as 0.04-0.07V.
Anyone have this issue happen? Short of tracing the green wires from the plug to the ECU and check continuity, i am stumped as to why im not getting higher voltages. Since 0.5-4.5V is the measurement for the sensor. And it should be a simple plug and play, the only difference in wiring is power and sensor wires are reversed between how the factory map sensor is vs aftermarket pressure sensor.

connector latch is facing down
red to brown, black to black, white to green
if you have it wired correctly i would check the voltage input at the sensor and the voltage output at the sense, I have some issues with my sensor where it flakes out occasionally and i think it is the sensor itself.

Just wanted to give a heads up, the Innovate sensors are great and very reliable and my issue turned up to be the harness plug, one of the sensor out on the sensor side (white) the metal pin in the connector was not making a full contact! Drove me insane, but all is well now!
Thanks to all those that provided their input and wiring colors helped as well!
