Code help

$
0
0
Finally got caught up after being gone and got the fresh set of stock turbos back in the stage one test car til the wheels come in and am now having another issue.

Getting codes:
P0237 TC Boost Sensor Circuit Low Voltage
P0238 TC Boost Sensor Circuit High Voltage
P0056 HO2S Heater Circuit Bank 2 Sensor 2

Also it wont come out of Limp home mode. It goes back and forth between the top 2 codes but the bottom one is constant. I already ordered the O2 sensor and will prob just swap it if I have to. My question is. The top 2 codes any info you can give me and will these codes cause a limp home trigger? I want to make sure I am chasing the right problem. As soon as this is squared taking the car to get a baseline.

Thanks in advance for the help.
