Just wondering If some one could look at my logs and let me know if something is out of wack.

Car is 2002 Turbo, have been chasing some problems, ABS/PSM lights CEL for P0507, P0420, P0174.

The CEL started after I put on a used TechArt exhaust with 200 cell cats.

Also had issues with low charge voltage.
First replaced the MAF.
So last night I replaced the voltage regulator on the 120amp Bosch Alternator.
Cleaned the throttle body.
Replaced the turbo to exhaust gaskets that I should have done when I swapped the exhust the first time.

Made sure I zipped tied all the vacuum lines I could find while I had everything apart. Ran out of time before I could do do a boost leak test but everything looked good.

So any help I would be grateful.

Thanks,
Jason

 

I'm sorry but I can't help you with the logs but was wondering how was the TB cleaning? Did you have to lower the engine out of the engine bay for access? I am under the impression that this is required, so if I was to do it, I would try to do some other things simultaneously.

 

That was easy to get to once the y pipe was out.
You are probably thinking about the plenum witch is behind that and need more room to get out.

 

Those codes are for high idle and O2 sensors, not ABS/PSM. Did you replace all 4 O2 sensors when you installed new exhaust? They are damaged easily upon removal from stock exhaust after years of being in there.

Also, DAMN your car needs some intercoolers. IATs jump over 100 very quickly and you're getting a lot of timing pull.

Check out my IATs with Cobb stage 2 and 997 GT2RS intercoolers. Only a 7 degree delta on a third gear pull to 7000rpm.
