Question about 2004 GMC Sierra 2500

Which side is bank 2 on 04 yukon for sensor 2 replacement

I have an 04 gmc yukon and the check engine light came on. The code tells me that the bank 2 sensor 2 is bad which is the post-cat sensor. What I can't figure out is which side is bank 2 located on. The driver or passenger. The engine is 5.3L Vortec flex fuel. The vin offers a "Z" if that matters in any way for engine type. HELP!!

    I changed the sensor and drove the vehicle but the light is still on. Does it have to be reset by the scan tool or disconnecting the battery for a few minutes reset the system????

If you look at the front of the motor you will notice one cyclinder is further forward then the other... that first cyclinder would be 1. i'm guessing the side opposite to cyclinder one would be bank two.

Where is the oxygen sensor located on a 1999 GMC Yukon with a 350.


You have four O2 sensors in your vehicle. Bank 1 and Bank 2. Typically it is Bank One, sensor Two that goes out from minor oil leaks on your engine. Here are a couple diagrams. Lay down behind your right front tire and look up. Look for cracked wires or burnt areas by connection. You can't always tell by looking. Easy to replace and fairly cheap.

Trouble codes? If none, then check O2 sensor outputs and replace as needed. Could be a leaking intake manifold gasket if you get "lean banks" codes. This happens in cold winters, but fixes itself in Spring.

Hi, There are 4 sensors, 2 pre catalytic converter, 2 post. The driver side is bank 1, and the passenger side is bank 2 .The foreward one in the pipe coming from the driver side is bank1 sensor 1, the rear sensor for the driver side is bank 1 sensor 2 . The other side would be the same, but bank 2. Good luck...

I have an engine code PO332 knock sensor 2 circuit low imput bank 2 what is this problem .the car is a 2001 gmc yukon xl .


The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.

CHECK ENGINE LIGHT IS ON, GOT CODES P0157 2 TIMES,


the bank 2 sensor2 is used to check that your catylitic converter is working on that side of the exhaust. without seeing the car and doing sensor tests, it would be a gamble to say replace the sensor. so you can replace it and see what happens or take it to your favorite shop for further diagnosis

you may have two oxugen sensors on your yukon. if so the oxygen sensor that controls that bank may be bad. from what you mentioned in your complaint, it sounds like it is the oxygen sensor.
