I am getting P0101 after replacing my MAF sensor. The freeze frame, which is the diagnostic reading app report at the time the code came in reports the following related metrics:
04 Calculated Engine Load Value 54.5 %
05 Engine Coolant Temperature 81 °C, 178 °F
06 Short Term Fuel Trim Bank 1 0.0 %
07 Long Term Fuel Trim Bank 1 21.1 %
08 Short Term Fuel Trim Bank 2 0.0 %
09 Long Term Fuel Trim Bank 2 18.8 %
0C Engine RPM 2128 rpm
0D Vehicle Speed 92 km/h, 57 MPH
10 Mass Air Flow Rate 29.23 g/s, 3.87 lb/min 1
15 O2 Bank 1 - Sensor 2 - Short Term Fuel Trim 99.2 %
15 O2 Bank 1 - Sensor 2 - Oxygen Sensor Voltage 0.700 V
19 O2 Bank 2 Sensor 2 (Bank 3 Sensor 2) Short Term Fuel Trim 99.2 %
19 O2 Bank 2 Sensor 2 (Bank 3 Sensor 2) Oxygen Sensor 0.485 V
Could the MAF rate of 29.23 g/s, 3.87 lb/min be the reason for the code? Right now, when I accelerate the RPM to about the same (~2100), I get something like 1.1-1.2 lb/min? What could be the reason this happened? Vacuum leak somewhere along the air intake?
