Oxygen Sensors
Hello, first post. I have a 2013 Scion FRS and I recently had a motor swap. The engine has been running really rough and is currently running rich with a bunch of smoke burning out the exhaust. I suspect the problem is coming from the Oxygen sensors, but I need to know what the proper voltage specifications are for the Oxygen sensors? Does anyone know this info? Thanks.

The O2 and MAF operate in a voltage range. The only way to really test them is resistance across the pins at a specific temperature.
https://demos.starbase7.net/t3Portal..._rm_index.html Look under Engine/Hybrid System -> FA20 Engine Control and the inspection procedure for the Air fuel ratio sensor and the heated oxygen sensor. I doubt this is your issue though.
