Guide To P2481 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P2481 can be described as Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 5. The error code P2481 would start triggering when the PCM would detect some fault in exhaust gas temperature sensor circuit. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

Don’t worry if P2481 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. The P2481 trouble code would indicate that an exhaust gas temperature sensor circuit which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination in the malfunction indicator light. “Bank 1 Sensor 5” here refers to a particular sensor at a specific location in the exhaust stream.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 5?

• Defaults in the exhaust gas temperature sensor bank 1 sensor 5
• Exhaust gas temperature sensor bank 1 sensor 5 harness might be unlocked
• Exhaust gas temperature sensor bank 1 sensor 5 circuit might have bad electrical connection
• Leakage in the exhaust
• There might be a lot of particulate matter build up on sensor

1. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
2. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
3. Exhaust Gas Recirculation Valve - It is auto part commonly found on many road going automobiles. It is a part of the vehicle’s exhaust gas recirculation (EGR) system, an emissions system that is designed to recirculate exhaust gases back into the vehicle’s intake so that it can reduce cylinder temperatures and NOx emissions. Purchase top notch exhaust gas recirculation valve from us at economical prices.
4. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.
5. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P2481 error with the help of experienced mechanic. Visit us today!
6. Catalytic Converter - Excessive amounts of unburned gas caused by a misfiring spark plug or a leaky exhaust valve can cause overheating of catalytic converter. Replace your old catalytic converter now!
7. 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!
8. Fluid Pump Control Module - Faulty fluid pump control module will result in the fluid pump not working properly. This will cause transmission issue and erratic behaviours. Replace faulty control module immediately.
9. Engine Coolant Temperature Sensor - The most common symptom which is associated with the issues in the engine coolant temperature sensor is the poor fuel economy. Reduction in the fuel economy would also hinder engine performance. Purchase top notch engine coolant temperature sensor online.
10. Exhaust Gas Temperature Sensor - An EGT sensor measures the temperature of the engine exhaust gas to prevent damage to critical components such as the after treatment system, turbines and cylinder head exhaust valves. It can also be used inside the combustion chambers where hot gases are generated. Thus, replace the faulty component now!
11. Diesel Particulate Filter - A diesel particulate filter (DPF) is a filter that captures and stores exhaust soot (some refer to them as soot traps) in order to reduce emissions from diesel cars. But because they only have a finite capacity, this trapped soot periodically has to be emptied or 'burned off' to regenerate the DPF. Thus, replace it now!

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2481 code by mentioning some major symptoms below:

Common Symptoms

• Illumination in the service engine soon light
• Lack of power
• Some drivability related issues

Here are some ways with the help of which you will be able to correct the OBD Code P2481:

• Rehabilitate the defaults in the PCM/ECM
• Make sure to mend the faulty wiring to the EGT sensor
• Repair or replace the quirky EGT sensor
• Carefully adjust the faults in the ECM
• Recondition the non-functioning catalytic converter
• It is necessary to perform proper Diesel Particulate Filter Regeneration procedure with a scanner

Here are some steps which you should follow in order to diagnose this P2481 fault code:

• EPA (Environmental Protection Agency) emissions requirements for catalytic converter systems on diesel engines have been relatively lax, until stricter regulations were implemented between 2007 and 2010. Now as more complicated catalyst systems has been introduced, it is very essential that the mechanic should spend extra time to study the particular system that they are working on.
• First of all a scanner should be connected to the automobile to inspect as well as monitor for all codes and appropriate data should be the first step. There is a different programming of every manufacturer and design specifications that will dictate the procedures to be followed for the diagnosis of their specific system. Here are some steps which the technician should follow:
• First of all the automobile should be scanned for all the stored codes.
• The catalytic converter system should be visually inspected.
• The connector at the affected sensor should be disconnected and inspect for resistance and or voltage specifications provided by the manufacturer. It should be done for the sensor, wiring to the sensor and the PCM.
• There are some manufacturer-specific procedures which should be followed while doing this.
• Run various bidirectional tests with the scanner (just keep in mind that these tests are particular to each manufacturer and can only be carried out by using a scanner).
• After that the technician should evaluate the freeze frame data.
• Observe the exhaust gas temperatures on a test drive to duplicate the conditions shown in the freeze frame data (these codes will often occur under specific conditions, such as towing a heavy load up a steep grade).
• The EGT sensor should be removed and inspect for contamination.

Common Mistakes When Diagnosing The P2481 Code

It might be very difficult to diagnose this error code. That is the reason why there are many shops which won’t work on diesel engines. Keep this thing in mind that the emissions systems for diesels are different from gas engines. The diesel engines are not as common as gas powered automobiles and that’s why there are a lot of shops which do not work on diesels due to their relative rarity in comparison to gas powered automobiles.
