    Sensor error when running AHT diagnostics

    I have an mid 2012 Macbook Air, the previous owner had changed the SSD and the battery (aftermarket SLODA battery).
    Anyhow it works great, no faults, but when I ran the AHT diagnostic tests there where two faults, the TB1T and TB2T sensor. Do these sensors sit in the battery?, and may the cause be the replacement battery?.
    Like I said there is nothing wrong with it, no overheating, charging works like it should and batterylife also good.
    What do you guys think, should I be concerned about these two error codes?.

    OK, the TB1T and TB2T sensors are battery related, and may very well have been tripped because of the 3rd party battery replacement. However, if everything is working as expected, then I wouldn't be overly concerned.
