GregKneupper Posted July 30, 2009 Share Posted July 30, 2009 I have a 2006 lcf here with codes 163 and 365. The egr valve and egr driver were replace approximately 12000 miles and 2 years ago by our sister dealer. It was at another shop before being brought to me and that shop also replace the egr valve. At first the codes were hard faults and I could not clear them. I followed pinpoint test W which led to replacing the valve. But since the valve is new I would imagine that it is not the cause. Now the codes are gone and I cannot duplicate the concern any more. I have checked power and grounds to the valve and the driver module and they are all good. I have also checked all the wires in between the driver and the valve and have checked pin fit. My experience with lcf's is limited and have never encountered this concern. Is it possible that the driver module has failed again? Quote Link to comment Share on other sites More sharing options...
