P20E6 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P20E6 can be described as Reductant Injection Air Pressure Too Low. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. This would also give rise to the illumination of the check engine light.

Here is some more information about this error code. It is the catalyst system which is fully responsible for reduction of all exhaust emissions although certain applications are also equipped with a NOx trap. The exhaust gas recirculation systems go another step further in the reduction of NOx.

What causes this problem with the Reductant Injection Air Pressure Too Low?

• The reductant injection air pressure might be too low
• The reductant injection air pressure sensor system circuit might be opened or sometimes shorted
• There can be distorted reductant injection air pressure sensor
• Some flaws in the SCR controller/PCM or programming error

1. Automatic Transmission Module – Sometimes the automatic transmission module is unable to communicate or correctly anticipate the speed of the vehicle and thus creates difficulty in gear shift leading to sluggish acceleration, throttle response and stalling. Thus can also hamper a lot of components physically and thus must be check for and replaced, if required.
2. 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.
3. 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.
4. Fuel Injector – The fuel injectors are important component of the fuel delivery system that helps in proper utilization of the fuel entering the engine. This not only helps in taking care of the air to fuel ratios in the engine, helping the combustion process but also enhances the performance. Thus, replace faulty injector now!
5. 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.
6. 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.
7. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P20E6 error with the help of experienced mechanic. Visit us today!

Do you wish to diagnose P20E6 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.

• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the reductant injection air pressure itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and reductant injection air pressure.
• If the reductant injection air pressure or other related parts are not faulty, he will then retune the code and test drive the vehicle.

• Now when the car is taken out for a test drive, if the P20E6 code does not return soon, he will know that there is an existence of erratic condition.

Common Mistakes When Diagnosing The P20E6 Code

• The reductant injection air pressure sensor might start failing
• Non observance of the powertrain control module
• Some issues with the car wiring
