I am recovering from a fuel pump replacement, and I could tell before pump completely quit that something was goin down hill. But it stll drove and boost was slow to build. After the pummp replacement iI pulled the codes, and got :

83
22
42continuous
64
65

my Question is could this be one part or sensor that could cause all these codes. My scanner died on me before I could do the key on engine on portion. But this would get me a good start. Checked intercooler hoses, and wga, hoses sealed and wg is not stuck! Any suggestions? ANY HELP IS GREATLY APRECIATED, CAr only makes 10 pounds of boost!

The last things I had done were my gillis, and k&n on vam, before pump went out had gillis @ 13-14 psi, changed nothing, now all I get is 10 psi, I think that is why the system rich code is there (42). But the rest have stumped me.

83 is a problem with the high speed cooling fan drive circuit. Is your set up non-stock?

22 is your barometric pressure sensor is out of range on the voltage (engine 0ff) It is the little box with what looks like a vacuum port facing down. It is mounted to theback side of the IRCM. Check the electrical connector for corrosion and re run KOEO codes. This might be related to other codes

42 continous - Sometime in the past your 02 sensor reported a rich condition and that it was not switching between rich and lean like it should. This could be caused by something else. First step would be to erase the continous codes, drive the car and see if it comes back. It might be something recent or it could be older.

64 says the ACT sensor or the VAT sensor voltage is too low. I'll email you some info
for checking them. This might influence the code 42.

65 - probably indicates the engine never went into closed loop operation. Probably reltaed to the code 42.

Thanks a million Pete, That 'll be enough to keep me busy in my spare time.
