P2486 - OBD Trouble Code

<<See All OBD Codes

Is your vehicle engine performance decreasing and you notice an increase in the fuel consumption and exhaust emissions? Do you notice the Malfunction Indicator Light illuminated on the dashboard? If there are faults in the exhaust system of the car, especially the exhaust gas temperature sensor, then P2486 fault code is definitely going to trigger up.

OBD code P2486 means Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 5 Issue.

This EGR valve is controlled through an EGR temperature sensor. The sensor collects vital information and based on this information, the EGR valve determines when to open and close. When the EGR temperature sensor fails, it causes various issues with the EGR system and the situation should be addressed quickly. Thus, when the PCM notices that the EGT sensor 5 for bank 2 has low voltage output, OBD code P2486 gets stored in the system.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 5?

• Loose or corroded connector or terminals
• Exhaust gas temperature sensor not working
• There might be a cat back exhaust system without EGT provisions installed
• Failure in the powertrain control module

1. Engine Control Module – ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
2. Electronic Control Unit – The ECU coordinates with the temperature sensor to control the blower fan for keeping the battery temperatures under control. So, replace faulty ECU components now!
3. Exhaust Gas Recirculation Valve - Did you just see check engine light flashing on your dashboard? If the computer would detect some fault with the automobile’s EGR valve circuit, then it would set up the check engine light so that the driver is notified about the fault. Don’t waste time and get them replaced or else this fault code can turn up.
4. Fuel Injector - Faulty fuel injector, it will cause rough idles and difficulty in starting. Also, it will affect the fuel economy and engine performance. Fuel injector can also crack or break leading to leakages and should be replaced immediately.
5. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new one from us!
6. Powertrain Control Module – Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
7. Oxygen Sensor – Inspect for faulty O2 sensor that can affect the engine combustion process and the exhaust emissions. Thus, it is important to understand its importance and replace faulty oxygen sensor now!
8. Manifold Absolute Pressure Sensor - The MAP sensor would fail by getting clogged, contaminated, or sometimes damaged. There can be times when the engine heat would “overcook” the electronics of the MAP sensor and can cause cracks vacuum lines. So it is very important to take proper care of the MAP sensor and in case you need a new one, then Parts Avatar is here at your service.
9. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
10. Exhaust Gas Temperature Sensor - If the computer detects a problem with the sensor circuit or signal, it will set off the Check Engine Light in order to notify the driver of the issue. The Check Engine Light can also be set off by a wide variety of other issues, so having the vehicle scanned for trouble codes is highly recommended.

Next important thing you need to know about are the common symptoms for this obd error code P2486 with your fuel volume control.

Common Symptoms

• Check engine light on
• Engine running too rich or lean
• Exhaust leakages
• Knocking sound from the engine

Wish to correct this error code with your vehicle? Do you know what all you should do to make your car free from this code? Well, don’t worry! We are here to guide you.

• Remove and clean excessive soot and ash off of the EGT sensor
• Adjust the faults in the EGT sensor carefully
• Repair or replace damaged wiring and connectors in relation to sensor circuit
• It is necessary to perform proper service of the exhaust leak in the pipe connection above the sensor
• Adjust the flawed electronic control unit

Apart from this, you might need to replace other damaged parts too like Powertrain Control Module, PCM, Exhaust Gas Temperature Sensor, Diesel Particulate Filter, Engine Control Module, exhaust valves, intake valves 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.

Here are some steps which you should follow in order to diagnose this P2486 fault code:

• A qualified mechanic will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After carefully inspecting all the components visually, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Scan as well as document the codes in the engine control module and then the freeze frame data should be looked upon for some failures.
• Inspect the EGT sensor and wiring itself to see if they are faulty or damaged. Examine the exhaust temperature of the EGT sensor 5 for bank 2. After that the sensor should be replaced if its reading are not as per the specifications set by the manufacturer.
• Make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful.
• Check for the faulty in the PCM and replace and reprogram it, if required. Although this problem is rare but can cause multiple codes to set in the system.

Common Mistakes When Diagnosing The P2486 Code

Many a times the mechanic might not remove the EGT sensor and forget to inspect for excessive soot or ash on the sensor. Thus, make sure that the EGT sensor is cleaned properly and it should be retested first before replacing it directly. Also check for faulty wiring and connectors and replace them immediately.
