Check engine light is on
I have a check engine light with a code of P0401- Exhaust gas recirculation flow insufficient. The EGR valve has been changed with no help. There is suction on the vacuum line on the EGR valve. I was told earlier that it may be the DPFE sensor but after checking with a few parts stores, they don't have that part listed. They have a EGR pressure sensor and a EGR position sensor. Does anyone know which one I need to buy?
