Guide To P2567 OBD Error Code Solutions

If you are looking for information with respect to the P2567 error code, then you are the right place. The direct ozone reduction catalyst temperature sensor circuit is usually known as the direct reduction catalyst temperature sensor circuit. There is a special coating available in the radiator of a few super low emission vehicles so that they can convert the smog in the surrounding air oxygen.

The environment air catalyst sensor is permanently fixed to the radiator of the vehicle. You have to fix a new OE radiator and code it to the engine computer if the sensor fails. The p2567 error code will get stored, if the sensor fails or an aftermarket radiator is installed.

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

• The ozone reduction catalyst temperature might be faulty.
• There is a high chance that the oxygen sensor is faulty which usually accompanies with the ozone reduction catalyst temperature code.
• Fuel usage might be improper.
• More amount of fuel will be pushed into the exhaust due to the defective coolant temperature sensor, mass air flow sensor, manifold air pressure sensor, fuel pressure regulator, or fuel injection component, an ignition misfire, slow spark timing, or the contamination of the oil.

1. Radiator - You will notice a sludge in your radiator if it is faulty. Get a new radiator for your vehicle from PartsAvatar.
2. Oxygen Sensor - The engine will start misfiring if the oxygen sensor is defective. Get the right oxygen sensor for your vehicle from PartsAvatar at the best prices to avoid P2567 error code.
3. Exhaust System - If there is a loud roaring noise in the vehicle, then it’s high time to replace the faulty exhaust system and get rid of the P2567 error code.
4. Airflow Sensor - Hesitation of the engine to start during acceleration is a sign of a damaged air pressure sensor. Get rid of it as soon as possible.
5. Engine Control Module - Does your car jump start on reverse polarity? It is an indication of damaged ECM. Repair / replace it soon to avoid P2567 error.
6. Powertrain Control Module - If you find the check engine light on the display dashboard, then the PCM is faulty. Replace it as soon as possible to avoid the P2567 error

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2567 here:

Common Symptoms

• Illumination of the service engine soon lamp.
• The engine might not start at all or the stall condition will prevail.
• Drivability issues might arise if oxygen sensors are problematic.
• The engine will hesitate to start if the internal components are molten or the direct ozone catalyst is damaged.
• During acceleration, there might be hissing noises arising from the engine.

Here are some ways with the help of which you will be able to correct the OBD Code P2567:

• The ozone reduction catalyst temperature sensor must be replaced.
• Changing the catalyst if it is defective over temperature conditions.

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

• As you proceed with the diagnostic procedure, ensure that the direct ozone reduction catalyst is not under the warranty of the manufacturer.
• 100,000 mile federally mandated warranty is usually carried by a direct ozone reduction catalyst regardless of the year or the model of the vehicle.
• If you find the system to be leaky, fix them as needed and retest the code as well as the system.
• You will need many tools for the diagnostic procedure if no leakage is found.
• Diagnose the code with the help of a scanner and DVOM.
• A manufacturer’s service manual will be essential.
• Carefully check the wires and connectors.
• The damaged wires, connectors, and other components have to be separated and repaired.
• After each successful diagnosis, recheck the system. Attach a scanner to the vehicle if every component is in proper working conditions and then retrieve both the stored codes and freeze frame data.
• This is highly helpful to find if there are any irregular conditions which made this error code to get stored in the vehicle.
• Clear all codes and retest the vehicle to see if any error has occurred.
• This will help you to know if the condition was irregular. Clear all codes and retest the vehicle to see if an error appears again.
• The condition will be erratic if the code does not show up instantly.
• In one such situation, you have to worsen the condition of the vehicle before proceeding for further diagnosis as this is a challenging task.
• Lift the vehicle and point the temperature gun at the exhaust pipe ahead and after the direct ozone reduction catalyst device.
• Link your finding with manufacturer’s specification.
• If the findings do not link as per the recommendation of the manufacturer, then the direct ozone reduction catalyst device or the temperature sensor can be malfunctioning.
• If the findings agree with the manufacturer’s specification, with the help of a scanner and oscilloscope, Check the upstream and downstream oxygen sensor operation on the engine bank which seems to be affected.
• Test drive the engine and start the vehicle. Allow the vehicle to idle.
• Once the engine touches normal operating temperature and when the engine control system arrives close loop operation, the upstream sensor will vary quickly from lean to rich.
• The downstream oxygen sensor must find reading at the centre and it must stay in the same position as long the engine idles.
• If the downstream oxygen sensor changes in the same pattern as that of the upstream oxygen sensor, the catalytic sensor can be faulty.
• If both the upstream or downstream sensor responds slowly or fails to respond as per the engine conditions, then the sensor can be damaged.
• In one such scenario, the oxygen sensor must accompany the direct ozone reduction catalyst temperature code.
• Oxygen sensor codes, fuel trim codes, fuel mixture codes, or misfire codes must be changed and fixed before diagnosing the direct ozone reduction catalyst temperature code.

Common Mistakes When Diagnosing the P2567 Code

• Faulty EAC sensor code to the PCM.
• Defective EAC sensor.
• The radiator fails to meet the manufacturer’s requirement.
