Has any had this CEL before P1405. I went to Autozone to pull my codes because my CEL is on. I got P0401 insufficient flow EGR, from what I read on other post this probably is DPFE sensor however, I don't know what P1405 code is. Any ideas.
Thanks

P1405
P1406 DPF-EGR Sensor Upstream Hose Off or Plugged
DPF-EGR Sensor Downstream Hose Off or Plugged
These codes are set by the engine computer detecting a vacuum leak or vacuum hose being plugged on the Differential Pressure Flow Exhaust Gas Recirculation (DPF-EGR) sensor. The upstream and downstream hoses are located on the intake manifold. Use a vacuum pump to test the line for a blockage or leak.
