I have a ford 2003 windstar that was running very rough when cold and almost stalling. engine light came on. went to autozone and they read the codes for free and told me it was running lean on Bank 2 also. i came home searched for the O2 front sensors online using the info autozone gave me. there are 2 front sensors on my car that need to be replaced at the same time. look for ones that have a direct plug in and don't need wire splicing. the ones without the wiring harness are cheaper but more of a pain, i think.
they were fairly easy to replace. getting access with the wrench was the worst. reset the light by disconnecting the battery for a few minutes. seems fine now and the light hasn't come back on.

This is Bank 1 (closer to the dash panel) Sensor 2 (located after the catalytic converter).

---
Note: A malfunctioning front oxygen sensor may cause fuel trim codes to set.

Several Diagnostic Trouble Codes use specific terminology to refer to sensor location. The illustration and key below explain the following terms:
Engine BANK Bank 1 is closer to the dash panel, (also referred to as RH or right hand). Bank 2 is closer to the radiator, (also referred to as LH or left hand).
UP Refers to Sensor 1 or "front sensor". It is located closer to the exhaust manifold and before the catalytic converter.
DOWN Refers to Sensor 2 or "rear sensor." It is located after the catalytic converter.
The following examples show how to interpret oxygen sensor terminology:
B1/S1 = Bank 1/Sensor 1 = Dash panel side, BEFORE the catalyst or "upstream"
B2/S2 = Bank 2/Sensor 2 = Radiator side, AFTER the catalyst or "downstream"

Pluged in the computer to my truck and it said there is a o2 sensor malfunction of bank 2. how do i find it? also it says the truck is running to lean. is this cause by the o2 sensor?

Yes, this too lean runing engine is due of oxygen O2 sensor malfunction. Must be replaced with new one. You can find it very simply on bank 2. The bank 1 of V8 engine is the cylinder bank on the right (passenger's) side of the car, (for Left Hand Drive vehicles). So the bank 2 is placed on the left (driver's) side of the car, (for Left Hand Drive vehicles). The bad oxygen O2 sensor is fitted on bank 2, so you can replace it.

Please rate my response. Thanks!

I have a 2004 Ford expedition, does it have a PCV valve? If not what is it called and where is it located?

The PCV valve is going the way of the carburetor, they are being phased out by "most" companies. If you can't find it, most likley it's not there. Thank you, Dana
