Cat was just stolen and now brakes aren’t working

Welcome to PriusChat!!

Not sure which obd2 device or app you're using (many aren't compatible), but would you like for me to use the Pchat search feature (working again) to retrieve those obd2 codes (aka DTCs). and corresponding step by step factory workups for you, or can you manage it alone?

Best to isolate those downstream o2 sensor electrical leads from one another, and see if something changes. Usually that blows an ECU.

Sure thing, or no problem. Below are the step by step workups for the posted obd2 codes (DTCs).

Here is the workup for DTC C1256 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/21avn/cic12565.pdf

Here is the workup for DTC C2122 : It would appear that a TPMS sensor has given up the ghost (how many miles are on the vehicle?)

Here is the workup for DTC C2123 : It would appear that a TPMS sensor has given up the ghost (how many miles are on the vehicle?)

Here is the workup for DTC C2124 : It would appear that a TPMS sensor has given up the ghost (how many miles are on the vehicle?)
