Anyone have troubleshooting for this fault code? Only have access to Jpro and not a lot of information on there. Thank you

Thank you! Any idea where that fuel intake pressure sensor is located? I know on the 2011 trucks the module is on the left rear of the engine but this is 2014 with a cartridge style filter not a spin on

The sensor is mounted on the rear of the engine fuel filtration module on EPA 13. Right next to the 2 solenoids which are the air and fuel shutoff solenoids for the fuel doser. The sensor is the 3 wire.
