P2BEE code/ fuel control system A too lean Bank 2

[mdrakev.0]

Hey guys I got a check engine light the other day and scanned my Mustang and got a P2BEE code. Does anyone know what it means? I’ve done research and it’s could possibly be bad o2 sensors, vacuum leaks, dirt/bad injectors, exhaust leaks at or before the upstream o2 sensor. Does anyone have any recommendations on how to diagnose this?

Get a smoke test machine to start. If you don't see anything from that or any exhaust leaks I'd change o2 sensors next.

I'd certainly put a scan tool on the car first to find out how the O2s are working along with what the fuel trims are doing.
Throwing parts at a problem without proper diag can quickly turn into an expensive proposition.

I was going to make a diy smoke tester and check for some leaks. I scanned for codes and that’s the only code I got, it’s very vague. What kind of scan tool for the o2s?

Any code reader can pull basic codes. A bidirectional scan tool is much more versatile in that they can read live data and graph it so you can see, in real time, how different sensors are functioning. They can also activate many sensors and functions manually.
Which scan tool is best for you is not something I can answer. There's just such a wide range of options and pricing. Bidirectional scan tools start in the $200-$300 range and run to several thousand dollars. Obviously, the more expensive the more it's capable of. If you work exclusively on Ford, a product called Forscan is a very affordable and powerful option. You will need the program, a computer to load it on, and an OBDII interface dongle.

I’ll look into that scanner. Where do you recommend hooking up to perform a smoke test. The evap port?

"Rent" one off Amazon that builds some pressure.

I tried the DIY smoke makers. It mase smoke for sure but not really enough pressure to find tiny leaks that rear their head during engine operation.
