This is resisting repair. 71 means, "30 seconds from start of EGR operation, EGR gas temp. is less than 100* C (212* F) with coolant temp less than 60*C (140* F) or more, 2nd trip detection logic"
I have replaced the various VSV valves, the EGR temp sensor, and the old associated tubing. I have checked the components with a vacuum and pump as described in the manual. The EGR valve, EGR gas modulator, VSVs, and check valve B all function properly and check out.
The EGR valve is unobtanium, but does test good.
Any ideas on what is going on?
I doubt it is related but when I take the gas cap off after driving I get a hissing noise. That is the evap system? Unrelated?
