The P2573 Trouble Code refers to the detection of voltage in the direct ozone reduction catalyst deterioration sensor circuit that is out of the manufacturer’s normal operating range.
The powertrain control module utilizes the data from the oxygen sensors to determine the degree of ozone reduction catalyst deterioration for each of the converters. If the sensors do not detect the proper degree of deterioration, the P2573 code will be stored and the Check Engine Light could come on as well.
The following are the most common causes of the P2573 code:
As is the case with many trouble codes, the extent of the symptoms you might experience can vary greatly. For some drivers, the only issues will be the stored code and perhaps the Check Engine Light being illuminated. However, in many cases, there will also be issues with the drivability of the vehicle. The engine might chug and hesitate, and you could hear hissing sounds while you are trying to accelerate. In some cases, the engine might stall, or it might not start at all.
When the mechanic diagnoses the code, they will start by hooking up their OBD-II scanner to your vehicle. The vehicle has an onboard computer that stores the codes and data about the car or truck. The scanner can access this data and provide the technician with valuable information when it comes to diagnosing and repairing the vehicle. They also want to reset the vehicle and drive it to see if the code returns. This lets them know if the code was triggered by mistake or not.
The biggest problem with misdiagnosis for the P2573 code is not doing a full investigation into the issue that led to the direct ozone reduction catalyst failure. They make the wrong repairs because they do not dig deep enough to find the real cause for the problem with the vehicle.
The symptoms can vary quite a bit. In some cases, the driver might not know that the car has an issue until they bring it in for a checkup. However, there can be some serious issues with the vehicle as well, and it might be difficult to drive it. The car could stall, and it will not have the power that it should have. Never put off getting your vehicle checked out. Take it to a mechanic so they can deal with the P2573 code and any other issues the vehicle might have.
The following are some repairs mechanics can use for the P2573 code:
Technicians report that they will often see repeated failures of the direct ozone reduction catalyst when there are other codes present in the vehicle and they are left unattended. This is why it is so important for drivers to take good care of their car or truck and to get the repairs they need as soon as they present themselves. If you wait too long and a number of codes are stored up, it will mean greater problems with the vehicle and more repairs for the vehicle. Take the time to find a qualified mechanic who can diagnose and repair your vehicle.
