I have the following high/low voltage trouble codes. Do they collectively mean anything? Are they an indication of anything failing or just random codes that could get thrown by fiddling with the battery, etc.

Or is the way to troubleshoot this to clear the codes and see if they come back?



DTC P0113: Intake Air Temperature Circuit High Input

DTC P0102: Volume Airflow Circuit Low Input

DTC P0228 Throttle/Pedal Position Sensor/Switch "C" Circuit High
