Guide To P2050 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P2050 can be defined as Reductant Injection Valve Circuit/Open Bank 2 Unit 1. This trouble code would indicate that there is an open circuit detected by the PCM. This open circuit is generally produced due to a malfunction in the operation of the catalytic converter. Due to the malfunction, the quality of fuel mixture would also get affected.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P2050 error code. The reductant injection valve circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the reductant injection valve circuit would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Reductant Injection Valve Circuit/Open Bank 2 Unit 1?

• Faulty reductant injection valve
• The reductant injection valve control circuit might be opened or sometimes shorted
• Inadequate DEF in the reservoir
• Some flaws in the SCR controller/PCM or programming error

Our main motive is to achieve customer satisfaction as for us our customers are everything and that’s why we will help you to diagnose P2050 code by mentioning some major symptoms below:

Common Symptoms

• The service engine soon light can start lighting up
• Diminishing fuel efficiency
• A lot of black smoke might start emitting from the automobile’s exhaust
• Declining engine performance
• Other SCR related codes might be stored

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P2050:

• Replacing damaged connectors, terminals, or wiring associated with the reductant injector
• Make sure to mend faulty electrical connection
• It is essential to restore the flawed exhaust gas pressure temperature sensor
• Rehabilitate the defaults in the wiring harness
• Carefully adjust the leakage in the exhaust

However, if you face any issue then we have stocked a wide range of best priced catalytic converter, pcm, oxygen sensor, exhaust system, air pressure sensor, reductant injector valve, dpf filter and more to help you out in fixing your car.

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

This is a general type of error code which is diagnosed with the help of a scanner. The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data. If he happens to find any additional error codes, he has to address them as well. Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears. If the error code does not return, then there can be an erratic condition. Then the process of diagnosis should start. The mechanic should visually inspect the reductant heater system harnesses as well as connectors. Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective. After that all the stored codes as well as freeze frame data should be retrieved.

This information should be written down before clearing the codes and then the vehicle should be take out for a test drive unless and until the powertrain control module would enter the readiness mode or the code is reset. Now if the PCM enters readiness mode, then it would that this code is intermittent and might be very difficult to diagnose it. If this is the real case, then you should allow the conditions which have given contribution in storing this code to worsen before the correct diagnosis can be made. Carefully reset the code and then the source of vehicle information to get diagnostic flow charts, connector pin out charts, connector face views, as well as component testing procedures and specifications should be searched. This information would be very helpful in completing the next step of your diagnosis. The DVOM should be used to check the power supply to the SCR control system.

The fuses with the circuit loaded should be inspected so that the misdiagnosis can be avoided. Now if the right power (battery voltage) and ground circuits have been located, then a scanner should be used to activate the reductant injector valve and check the output control circuit voltage. Then if the voltage is not sufficient, then it would that there are some faults in the controller or it might have faced a programming error. If the voltage output circuit is as per the parameters set by the manufacturer, then DVOM should be used to check the reductant injection valve. If the valve is not as per the specifications set by the manufacturer, then it would mean that it has a failure. It is very important to replace it. Parts or components should not be replaced with reference to only a P2050 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P2050 Code

• The technician might not verify the reductant injector air pressure sensor circuit is open.
• He might not perform a thorough visual inspection of the catalytic converter or diesel particulate filter and associated components.
• Sometimes forgetting to clear the P2050 OBD-II trouble code once the problem has been repaired.
• The mechanic might set confused in the identity of the oxygen sensor for the exhaust gas temperature sensor and might restore the wrong component.
