Before i had a different code for P0152 02 Circuit High Voltage Bank 2 Sensor 1 I then replaced that 02 sensor.I cant win with this car just fixed speed sensor problem now there is another code for P0174 Bank 2 system Lean. I dont understand I just changed that sensor. Do you guys think I have an exhuast leak on that side. Maybe the ecu is sensing the leak on that side and telling me its lean on bank 2 so I can know what side?

All help is appreciated as always !!!!

After this problem is fixed car will be up for sale!!!!!!!!!!!!!

 

test pipes? maybe when you changed the sensor it was not really the problem. Exhaust leak is a possibility, but you would probably hear it. Reset the codes and drive it. Could just a be a fluke.

I have any part you need btw haha.

 

HFC Berk!!!! as far as the fluke... did the clear cel code later came back, but the first code went away (P0152) On the other side of the car (passenger side) when you let go of the gas pedal there is a gasp and vibration noise and rattle. But thats on the opposite side of the car that the cel is saying so i have no clue right now
