P2573 Severity
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
The Radiator on certain Super Low Emissions Vehicles (SULEV) has a special coating to convert smog in the surrounding air oxygen. The eac (Environmental Air Catalyst Sensor is hardwired to the Radiator of the vehicle. If the sensor fails, a new OE Radiator must be installed and coded to the engine computer (PCM). Failure of this sensor or installing an aftermarket radiator will result in code P2573 being set.
