2012 Chevy Cruze Code P0237 and P2227
Hello these code are for the Turbocharger/Supercharger Boost Sensor A Circuit Low and the Barometric Pressure Circuit Range Performance. I have replaced the Turbocharger sensor thinking that is what put my car into limp mode. Would the other sensor keep it in limp mode? Also do I need to disconnect the negative battery cable to clear the check engine light and take it out of limp mode.

Unfortunately a code relating to a system is not always due to a malfunctioning sensor . A good part of the time poor connections or inadequate info to the sensor is involved.
When the vehicle is placed into Limp Mode, it is to prevent addl damage to the vehicle components, or emissions are over the limits set.
A thorough check is required to verify proper operating power is available ,(power and grounds) . Some of these can be verified with a quality scan tool and others will require a voltmeter to do voltage drop testing , if necessary.. Because most folks don't have access to the required info, or the proper tools ,it is best and most times cheaper in the long run to have an equipped shop handle the problem.
