engine code emission below threshhold bank 1
We have a 2008 DGC 3.3ltr iv replaced the egr valve the O2 senso plugs and wires it still gets p402 below threshold bank 1 code any takers ideas I was thinking mabe egr solinoid .
first, clean the EGR tube to make sure it is not restricted.
second, pull the Battery Terminal off for 5 minute to get a hard reset.
third, maybe your New EGR valve is bad, did you get it from the dealer or Autozone?
