Code P0173 Chrysler Description
The P0173 code for Chrysler vehicles indicates that the fuel system 2/1 is running rich, meaning that there is an excess of fuel in the mixture being delivered to the engine. This can lead to a decrease in fuel efficiency, increased emissions, and potential damage to the engine and catalytic converter over time. The Engine Control Module (ECM) monitors the air/fuel ratio and adjusts it accordingly, but if it detects that the fuel mixture is consistently too rich, it will trigger the P0173 code. This issue can be caused by a variety of factors, including a faulty oxygen sensor, a clogged fuel injector, a vacuum leak, or a malfunctioning mass airflow sensor.
