Are you having an actual problem (and not just an error code that worries you, which may simply be a false positive)?
If your fan is running (or maybe NOT running) you can try to use one of the fan control utilities, such as
SMCFancontrol.
That will monitor your various heat sensor for actual temps, and also allow you to increase the fan speed, if that may be necessary.
I assume that your "tests" mean that you don't want to give up your MBPro for a sensor error that may not be really affecting you.
But, at least you can monitor your temps, adjust your fan speeds if you think that will be necessary. The IMPORTANT issue will be the actual temps reported by sensors, which you can use that software to track.
Then, when your school tests are complete, you can take in for service, if that seems necessary.
