P0147 GMC MeaningWhen the ignition is turned on, the battery voltage is supplied to HO2S 3 heater to provide for faster sensor warm-up, thus allowing the sensor to become active in a shorter period of time. Powertrain Control Module (PCM) reads the amount of time necessary for the sensor to become active after start-up. If PCM determines too much time was required for HO2S 3 to become active, the Diagnostic Trouble Code (DTC) P0147 will set.
