Throwing P0406 again.
Or maybe still!
Exhaust Gas Recirculation Sensor A Circuit High
I've been chasing/fighting this for several months now.
DPFE sensor replaced.
EGR solenoid replaced.
EGR sensor replaced.
Those were all standard replacement grade "Standard Motor Products" from RockAuto.
All 4 O2 sensors replaced.
O2 sensors were Denso from RockAuto.
Cleared codes, drove 10 minutes or so, shut off, started again, threw code.
Repeated pattern multiple times to verify it wasn't just a stored code that didn't clear.
Talk to me people... Point me in a direction... WTF could this be?
