Saturn Aura XE 2008 2.4L engine, error code P0102

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A P0102 code means your car's Mass Air Flow (MAF) sensor is reporting low airflow, which can indeed throw your engine into reduced power mode. Since you've already replaced the MAF sensor, let's consider a couple of other things. Check for any vacuum leaks or dirty air filters that could be affecting airflow. The MAP (Manifold Absolute Pressure) sensor is another potential culprit. It's usually located on the intake manifold. Given that the problem worsens with heat, a faulty MAP sensor or a wiring issue could be the cause. If you're not sure where the MAP sensor is, a repair manual or a visit to a friendly local mechanic can help you locate and test it.
