P113C CHRYSLER Meaning
The oxygen sensor is controlled by the Smart Oxygen module (smart O2 module). This module is an intelligent device that receives information, such as dew point indicator, engine speed, etc., from the main engine Electronic Control Module (ECM). It provides the oxygen concentration signal to the ECM. It also performs its own diagnostics and reports faults to the main engine ECM. The ECM then decodes the error message and converts it into a fault code.
