I a getting a P1239 on an Isuzu with a 3.5 L direct injection system. This code usually relates to the high pressure fuel system. Is there any way to get the values from the high pressure sensor? When I list the data, it shows FPR which I assume is the Fuel Rail Pressure, but the value (50.1) makes no sense for the high pressure system. That is the correct value from the low pressure fuel pump.
I use a Modis with 11.4.
Thank you
Tom
