Increased Emissions? Pulled codes...

Flip a écrit

Ok cool. J'ai aussi lu d'autres endroits. Je ne pense pas, sonne toujours plus agressif comme ma voiture de dérive tune .

J'ai fait l'O2 assez facilement mais le code est revenu donc j'attends mon lecteur de code pour entrer dans la poste. Je vais poster de nouveau dès que je reçois cela et tirer les codes à nouveau.

J'ai eu les codes réinitialisés juste avant de remplacer l'O2. Je l'ai conduit à la maison du magasin d'automobiles après avoir réinitialisé et remplacé le O2. Le code est revenu quelques jours plus tard. Y a-t-il moyen de le réinitialiser avant de remplacer l'O2 pourrait faire revenir le code quelques jours plus tard? Ou est-ce qu'il y a simplement un autre code (ou le même code) ?

Cela signifie que ce n'était pas la bonne. L'O2 défectueux est toujours utilisé.

That means that it wasn't the correct one. The faulty O2 still inuse.

Did you replace both of your upstream 02 sensors?

If you only replaced one then it will still throw the code.

When you pulled the codes it says X2 so you will have to replace both upstream 02 sensors.

Well it said bank 2 so I thought that I would only need to replace one. I can't see why they would always both go bad at the same time either.

Also thought the x2 meant the code occurred twice. Is this incorrect?

I have to check, but I think that Archiebabes is correct. When it says x2, it means that both of them are bad. But I have to check. I know that Bank 2 means that it is on the side of the number 2 cylinder. Pull up the codes again and posted for us, so we can help you more. Without me there, I really can't help much. Let me know.

Reset them and more came back, this time pulled:
P0175 System Too Rich (Bank 2)
Po172 System Too Rich (Bank 1)
P0175 System Too Rich (Bank 2)
P0172 System Too Rich (Bank 1)

Did you purchase an OEM upstream 02 sensor from the dealership?

I need to look at your car. Do you want to meet this weekend? Let me know. That is strange that you are getting too rich mixture on both banks, but replaced the O2 on one of the bank. Your fuel pressure sensor might be going bad. That is why your getting that code and then the too rich code. Because it can not regulate the pressure. Sending too much to the rails? Bring it to my house and lets take a look at it.

Let me know and I'll give you my number. Is your car still under warranty? And you do not want to wait too long. Dumping too much raw fuel in the system can really mess up your cats.

flip wrote

No warranty... I went ahead and ordered that fuel pressure sensor and will just return if it I don't need it. And yeah, don't want to ruin cats .

Hey Philip, it was meeting you. Did that fix your car? BTW, nice car. We need to lower that thing.

Guys, read your thread and i thought this had to be my issue, now I am being told I have all of these other faults. Can anyone please help me...


04/04/12 2B4C – Intake air temp fault plus sensor plausibility (LEAN code).
03/08/13 2737 – Change plausibility, cold start B1.
2737 – Change plausibility, cold start B2.
2B3B – Misfire #7.
04/10/13 27BB – Fuel system lamda/charge plausibility B2
27BA – Fuel system lamda/charge plausibility B1

It looks like the coil on cylinder# 7 is faulty. Your cylinder# 7 is a dead cylinder or not firing.

Well i thought that might be the case, and in that instance, i turned the car off and when i restarted it everything went back to normal.

Move forward a month and now i have the lamba errors on B1 and B2. Could it be that the oxygen sensors are causing all of this?
