I had a sporadic P0130 for awhile. So I ordered a brand new Bosch B1S1 O2 sensor and replaced it yesterday. Now I have a fricking CEL fest.

First it was for ground short codes for N80 valve, Secondary air pump, and o2 sensor. Wiggled the lines, checked the work once again, and reset the code. Then I checked the resistance for the O2 heater circuit and it was with in the range. I checked the measuring blocks 32 and 33 and all seem to be in the range. I tried to run 02 aging tests, but realized that the readiness code was not set to complete the test. Then during that time, once again CEL was on with P0130 and P1114, B1S1 O2 sensor heater circuit and B1S2 O2 sensor circuit. WTF?

I cleared the code last night I went to sleep. Today I had to drive about 70 miles and no CEL... I thought I was good. Then all of sudden I got P0130 and P1128. I also have a rough idle now. Now it is really getting to me. I guess I will check vacuum lines for a vacuum leak, but any suggestions at this point would be appreciated. Can a bad MAF throw all these codes? Also P0130 seems to be pretty consistent.

Thanks in advance.

 

Yes a bad MAF can cause that, i would also check for leaks after the MAF. Its gonna come down to a vaccum/intake leak, or a faulty ECM.

 

Faulty ECM??? dang, that does not sound good. I guess I will check for vacuum, clean the MAF and see what happens.

 

Well, yesterday was an expensive day. I checked the 02 sensor again and turns out that my brand new Bosch sensor was not getting any reading. Not only that I decided to check the ohm readings on the other 02 sensors and they were all pretty much at the end of their life. F%#K! I needed the car running for today, so I swung by the local stealer to grab the sensors. After taxes, pretty much $200 per pop... So after $800 later with busted and burnt hands, she is running fine again.

Anyways, I was able to take some pictures doing the front one. I will do a little write up later.

Thanks for your input Auditech!

And I once again wonder why I am driving an Audi!?
