Hi Folks! I have a 2010 F150 5.4 3v FX4 truck. I'm traveling and yesterday after a 400 miles trip the truck start to run rough and without the usual power. Today the CEL turn on and I stopped at Autozone and the scanner shows a P0150 code Bank 2 Sensor 1 failure.

What's usually the problems in these trucks when the scanner showathis failure?

Where is the Bank 2 sensor 1 located?

Thanks for your help.

We need the ACTUAL FAULT CODE, not some vague interpretive description, since there is no such thing as a fault code that explicitly say a sensor is defective.

B2S1 is the upstream sensor on the driver's side.

 

Thanks! Just rescanned again. The code it's the P0150

 

It's going to be a wiring harness or connection issue, a PCM issue, or a sensor issue. You'd have to perform the pinpoint diagnostics to isolate ... or just guess it's the sensor and replace it.

 

Thanks! Is the upsteam located between the catalist and the motor?

Thanks Roadie!

 

I already change the sensor. The problem must be other thing. In the last 100 miles the truck start to develop a nose in the pasanger side bank. The noise today it's a little louder and the truck is still tuning rough. I stopped at a gas and when turn on I hear a very hard knocking sound. I shut off immediately I didn't get the time to elaborate what kind of sound is it. Any idea? What kind of test I may run without making the things worse?

thanks!
