If you see fault code P1101 on your Buick Encore, don't panic - but it's important to address it sooner rather than later. Essentially, this code indicates that the powertrain control module (PCM) has detected an issue with the MAF sensor voltage. The vehicle will perform a Key On Engine Running (KOER) test, and if the MAF sensor voltage is outside the specified range, it will record P1101. The primary culprit is likely a faulty MAF sensor, though other possible causes include a dirty air filter, faulty MAF sensor wiring, or a malfunctioning sensor. Start by cleaning the MAF sensor to see if that resolves the issue, as it could be a straightforward fix that saves you time and effort.

The Buick Encore's P1101 trouble code pops up when the PCM (powertrain control module, which is also known as the ECM or engine control module in some vehicles) identifies an issue or inconsistency in the MAF (Mass Air Flow) sensor system. This occurs as the PCM runs a self-diagnosis known as KOER or Key On Engine Running.
