Error Code P2087: What It Means & What To Do?

<<See All OBD Codes

P2087 OBD code displays a very low engine performance and is called as an exhaust gas temperature sensor circuit intermittent bank 2 sensor 2. The information about the temperature of the exhaust gas which moves in and out of the selective catalytic reduction is conveyed by the EGT sensor to the engine control module. The P2087 error code will be set in the vehicle if the PCM identifies an improbable signal from the EGT sensor.

For the proper continuity of the circuit as well as the out of range high values, the EGT sensor is carefully looked after by the powertrain control module. The EGTS is placed either in front of the diesel oxidation catalyst or else the diesel particulate filter. The EGTS is identified by the exhaust gas temperature and changes it into a voltage and sends it back along with voltage signal to the PCM so that the conditions of the engine can be controlled to efficiently minimize the emission. When the EGT sensor fails to meet the factory specification, then the P2087 error will be set in the vehicle.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 2?

• Defective EGT sensor bank 2 sensor 2.
• The harness of the EGT sensor bank 2 sensor 2 might either be shorted or open
• The electrical connection might be poor in the EGT sensor bank 2 sensor 2.
• The exhaust might turn out to be leaky
• The buildup of particulate matter might be excessive on the sensor.

1. Powertrain Control Module - Does your engine turn off without any reason? Then it’s a high time to replace your PCM as it can be faulty.
2. Engine Control Module - The behavior of your engine will be very erratic if the ECM is faulty or broken. Get it fixed or replaced as soon as possible.
3. Exhaust Gas Temperature Sensor - The EGT sensor is responsible for reading the temperature of the exhaust. Do you find the EGT sensor in your vehicle to be damaged? Replace it quickly by getting a new one from PartsAvatar.
4. Diesel Particulate Filter - Do you find any strange or bad smell? Then the DPF can be burnt which has to be replaced quickly.
5. Catalytic Converter - One common reason for a damaged catalytic converter is the misfiring of the spark plug. Replace the defective catalytic converter to avoid the P2087 error code.
6. Diesel Oxidation Catalyst - The oxidation of hydrocarbons, carbon monoxide, and unburned fuel and oil can be triggered with the help of diesel oxidation catalyst as it functions as a filter. Do you find the DOC to be damaged? Replace it quickly.

Interested in knowing the symptoms to OBD code P2087? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

• You will not find any other trouble code in the vehicle other than the illumination of the service engine soon lamp and a trouble code that is stored.
• The wires might be corroded.

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue you need to follow certain steps, and to solve OBD error code P2087, you will need to undergo the following replacements:

• The faulty EGT sensor bank 2 sensor 2 has to be replaced.
• Fixing the opening or short circuit in the EGT sensor bank 2 sensor 2.
• Repairing the weak electrical connection in the EGT sensor bank 2 sensor 2.
• Clearing off the excessive particulate matter build up on the sensor.

Apart from this, you might need to replace other damaged parts too like PCM, EGTS, DOC, DPF, soon, catalytic converter, corroded wiring and more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free if your cart value happens to exceed $99.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2087 code to be stored:

• Lift the vehicle and identify the sensor. This error code refers to the bank 1 sensor, which means that it is placed on the sides of the engine which has the cylinder 1. It is situated in between the exhaust manifold and the converter and in case of the diesel, it is placed before the diesel particulate filter.
• It looks slightly different from the oxygen sensor which has just a plug with 2 wires.
• The vehicle which has the turbo will have the sensor right next to the turbo exhaust input.
• Carefully inspect the connectors for abnormalities like erosion or any loose terminals.
• Check the pigtail up to its connector as well.
• Visually inspect for any missing insulation or bare wires that can likely cause a short to the ground.
• The upward connector has to be separated and the EGT sensor must be removed. The resistance has to be checked with the help of an ohmmeter.
• Review both the terminals in the connector and you will find 150 ohms if the EGT is good.
• You will have to replace if there is very less resistance that is below 50 ohms.
• Keep looking at the ohmmeter while you heat the sensor with the help of a hair dryer or heat gun. The resistance should go down and go up as the sensor heats and cools. Replace it, if this doesn’t happen.
• If everything works perfectly, then measure the voltage by turning on the key at the engine side of the pigtail. If you don’t find 5 volts at the connector, you must change the computer.
• Another reason why this error code gets stored in the vehicle is that of the catalytic converter which has been changed in favor of the catback system.
• This is an illegal process which is punishable in many states and you must pay a huge fine if you are caught.
• For the removal of this system, it is always best to check the local and state laws since it emits uncontrolled emission to the atmosphere.
• Until this issue is fixed, you can reset the code by buying a 2.2-ohm resistor at any local electronic store.
• Throw away the EGT sensor and fix the resistor into the engine side of the electrical connector.
• Cover it up with a tape and the computer will be gratified that the EGT is working properly.

Common Mistakes When Diagnosing the P2087 Code

One of the common mistakes that happen when diagnosing this error code is that the identity gets mistaken. Most often, instead of the exhaust gas temperature sensor, the oxygen sensor is mistaken or it is understood that the exhaust gas temperature sensor is placed inside the heated oxygen sensor. Definitely, this is wrong and replacing the oxygen sensor will not give way to a proper diagnosis.
