Why does my Toyota engine have a code p0401?
When code P0401 is triggered, it’s because the DPFE sensor found too little recirculation. This code indicates that too much exhaust gas recirculation (EGR) is occurring — the result is an overly-rich mix of oxygen in the air/fuel ratio and higher engine temps.
