P 1401 is a code for differential pressure feedback egr circuit high input there is a small square sensor on the engine with a vacuum line here is some info Exhaust Gas Recirculation (EGR) System Monitor” Differential Pressure Feedback EGR
\015\012The Differential Pressure Feedback EGR System Monitor is an on-board \015\012strategy designed to test the integrity and flow characteristics of the \015\012EGR system. The monitor is activated during EGR system operation and \015\012after certain base engine conditions are satisfied. Input from the ECT, \015\012IAT, TP and CKP sensors is required to activate the EGR System Monitor. \015\012Once activated, the EGR System Monitor will perform each of the tests \015\012described below during the engine modes and conditions indicated. Some \015\012of the EGR System Monitor tests are also performed during on demand \015\012self-test.
\015\012The Differential Pressure Feedback EGR sensor and circuit are \015\012continuously tested for opens and shorts. The monitor looks for the \015\012Differential Pressure Feedback EGR circuit voltage to exceed the maximum\015\012 or minimum allowable limits.
\015\012The DTCs associated with this test are DTCs P1400 and P1401.
\015\012The EGR Vacuum Regulator solenoid is continuously tested for opens and \015\012shorts. The monitor looks for an EGR Vacuum Regulator circuit voltage \015\012that is inconsistent with the EGR Vacuum Regulator circuit commanded \015\012output state.
Do I change the EGR or the DiffPresReg
