I'll check again tomorrow morning

I checked that pretty well and even had smoke machine running though exhaust didn't see any leaks. I'll look again tomorrow

For o2 sensors use mvb 032 and 033 to graph them and which would I use for MAP and injector?

europaparts in Piscataway nj is only a hour from me I'm going to call them Monday see if they have it there I can come pickup a new downstream sensor.

This one came from autozone. Had a issue in another thread with rear 02 sensor amd it turned out being a bad ecu. Was geting no activity b1 s2 replaced ecu and now i have this code.

I don't have vcdcs in front of me but it is a brand new bosch sensor

Would bad map sensor cause lean code?

So far I've smoked exhaust for leaks and no leaks, smoke tested vacum lines no leaks. Sprayed carb cleaner between motor and trans and no change in fuel trims. Anyone knowing this car has a maf sensor?

Nothing else on or near airbox. On sensor only stamping I see is pbt-gf30 which appears could be a maf sensor

Is this my mass air flow senor I believe? When unplugged it doesn't make a difference in how it runs or throw a code for anything. When spray brake clean between motor and trans numbers do not change

This is the same car I was having issues where I ended up needing a ecu to get rid of a no activity code on b1 s2. https://forums.ross-tech.com/index.php?threads/45722/

I'll do that tomorrow. this was after driving it around awhile the 2.7 bounces between that and 3.7 at idle.

ill drive more and check back. Rear main seems fine no oil leaks and had smoke machine hooked up for 20 mins and did not see anything coming from between motor and trans and car was jacked up to see underneath.

I drove around neighborhood 15 miles and changed some here's at idle now. I'll drive it more later.

New ecu solved the issue! I now have a lean condition I started another thread on that.

I have a 2012 VW Jetta 2.0 non turbo and I am getting P2096 My exhaust has no leaks and neither does the vacuum system. I smoke test both. What else should I look for? Here are my fuel trims aswell Monday,28,October,2024,17:01:36:58701 VCDS -- Windows Based VAG/VAS Emulator Running on Windows...

Just Had a freind come over that has an 11 jetta put ithe ecu in his car and it throws same code b1 s2 no activity after driving a few miles! I just ordered another ecu and sending it to have immo deleted.

When I bought the car I bought it not running and person I got from thought was issue ecu so that put a random one in. Actual issue was timing belt sheared.

Ya I guess I'd rather not take a chance of damaging it. There both base model 2.0 CBPA so was thinking there'd be a chance

The immo is deleted on this car. I was thinking what if I took the ecu out and put it in another jetta see if that code appears on other car? I have a 15 jetta same configuration. That would tell me if I have a ecu issue?
