P2570 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2570 can be defined as Direct Ozone Reduction Catalyst Temperature Sensor Circuit High. The PCM utilizes the input data which is received from the upstream and downstream oxygen sensors to calculate the desired direct ozone reduction catalyst temperature in each respective converter. If the right temperature would not be detected, then this error code would be stored and there would be an illumination of the service engine soon light.

The direct ozone reduction catalyst temperature sensor circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the direct ozone reduction catalyst temperature sensor circuit signal would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Direct Ozone Reduction Catalyst Temperature Sensor Circuit High?

• Some flaws in the direct ozone reduction catalyst temperature sensor
• Direct ozone reduction catalyst temperature sensor harness might be opened or sometimes shorted
• Direct ozone reduction catalyst temperature sensor circuit might have inadequate electrical connection

1. Oxygen Sensor - An oxygen sensor plays a vital role in the fuel delivery system and air to fuel ratio mixing functions. Without this sensor proper combustion of fuel cannot take place, thus causing performance issues. Also the exhaust system will not be able to detect the emissions properly if this sensor becomes inactive, resulting in increased emissions from the exhaust. Thus replace faulty oxygen sensor today!
2. Exhaust System Parts - Performance issues are a commonly followed due to an erroneous exhaust system parts. If the parts become damaged or corroded, they can sometimes cause an exhaust leak. A leak or crack can lead to the vehicle to experiencing a significant reduction in power, ability to accelerate, and fuel efficiency due to the loss of back pressure.

3. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
4. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
5. Catalytic Converter - Catalytic converters at fault will lead to dropped fuel efficiency and performance along with increased emissions. Thus replace faulty parts now!
6. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
7. Diagnostic Tools - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!

Here are some steps which you should follow in order to diagnose this fault code:

• The direct ozone reduction catalyst is utilized exclusively to reduce exhaust emissions in gasoline burning vehicles with internal combustion engines.
• The direct ozone reduction catalyst is an in line device which would resemble a muffler or resonator in exterior appearance although it differs greatly from either internally.
• The direct ozone reduction catalyst would get hotter than a muffler when the engine is running and especially immediately after the vehicle has been driven.
• Retarded ignition timing, lean fuel conditions, and misfires in the engine can rise direct ozone reduction catalyst temperatures to dangerous levels.
• There might be some cases where the direct ozone reduction catalyst will reach temperatures that cause it to become "red hot" and present a high risk from fire if flammable liquids are leaked or spilled thereon.
• The direct ozone reduction catalyst will utilize a system of interwoven fibres which contain a high concentrate of platinum packed tightly into the metal housing to restrict and filter excessive noxious oxide fragments.
• The noxious oxide fragments are then incinerated by the extreme temperatures (500 to 800-degrees Fahrenheit) found inside of the direct ozone reduction catalyst.
• Before you start with your process of diagnosis, verify that the direct ozone reduction catalyst is not under a manufacturer's warranty.
• Direct ozone reduction catalyst devices typically carry a 100,000-mile federally mandated warranty, regardless of vehicle year model.
• If the direct ozone reduction catalyst device is not under warranty, then you should start checking for leakages in the auto exhaust system.
• If exhaust leaks are detected (particularly before the catalytic converter), then they should be repaired as per the requirement, reset the code, and then the entire system should be retested. A lot of tools would be required to successfully diagnose this code if no exhaust leaks are detected.
• A suitable scanner, a digital volt/ohmmeter, and a temperature gun would be needed to perform a thorough diagnosis.
• After that start with the visual inspection of all wiring as well as connectors.
• Repair or restore damaged, disconnected, shorted, or corroded wiring, connectors, as well as other components as per the need.
• Make sure to retest the system once the repairs are completed to ensure success. If all system wiring, connectors, and components appear to be in good working order, then you should connect the scanner to the diagnostic connector and carefully record all stored codes as well as freeze frame data.
• This information might prove to be very helpful in diagnosing intermittent conditions that may have contributed to this code being stored.
• The code should then be cleared up and then the vehicle should be operated to see if it returns.
• This will help to decide whether or not the malfunction is intermittent.
• Once the codes have been cleared, tests drive the vehicle to see if the code returns.
• If the code has failed to return immediately, you may have an intermittent condition.
• Intermittent conditions can be quite challenging to diagnose and in extreme cases they should be allowed to worsen before a correct diagnosis can be made.
• Proceed by raising the vehicle and pointing the temperature gun at the exhaust pipe before and after the direct ozone reduction catalyst device.
• Then compare your findings with manufacturer's specifications.
• If your findings do not coincide with what the manufacturer recommends, then there are some faults in the direct ozone reduction catalyst device or temperature sensor.
• If your findings are in line with the manufacturer's specifications, then use the scanner and oscilloscope to monitor upstream and downstream oxygen sensor operation on the affected engine bank
• Start your car engine, test drive the vehicle, then park it and then the car engine should be allowed to stay idle.
• Once the car engine has reached normal operating temperature and the engine control system has entered closed loop operation, the upstream sensor should fluctuate rapidly from lean to rich (approximately .350 to .900 volts).
• The downstream oxygen sensor should find a reading near centre (about .500 volts) and it should hold this reading as long as the engine idles.
• If the downstream oxygen sensor fluctuates in a similar manner to the upstream oxygen sensor, then there is surely some fault in the catalytic converter. If either the upstream or downstream oxygen sensors are slow to respond, or fail to respond, to changing engine conditions the respective sensor may be defective.
• However, if this is the case then an oxygen sensor code should also accompany the direct ozone reduction catalyst temperature code.
• Just remember to diagnose and repair oxygen sensor codes, fuel trim codes, fuel mixture codes, or misfire codes first before you start attempting to diagnose a direct ozone reduction catalyst temperature code.

Common Mistakes When Diagnosing The P2570 Code

• There are a lot of mechanics which do not properly investigate the main reason which led to direct ozone reduction catalyst failure. The repeated direct ozone reduction catalyst failure would occur when there is presence of other codes and they are left unattended for long periods of time.
• One another mistake which is made by the technicians is that they simply replace the oxygen sensor without even verifying it. They often replace the oxygen sensors to avoid costly converter replacement. This would not solve the issue, but would lead to added expense.
