How is P0128 diagnosed?
The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.
Can a dirty air filter cause a P0113 code?
A faulty IAT sensor is the most common cause of a P0113 code. Dirty Air Filter: A dirty air filter is the second most common cause of error code P0113. If your air filter is dirty enough to hinder airflow, your air intake system has to work harder or may receive inadequate airflow.
