Guide To P206A OBD Error Code Solutions

<<See All OBD Codes

Check engine light flashing on? Don’t know the reason behind it? No worries, Parts Avatar to the rescue! Here’s all you need to know about the error code P206A. This generic OBD-II code wiring issue is also referred to as a reductant quality sensor circuit. It can be seen that the engine computer (PCM) regulates the reductant catalyst system's application of DEF and its capability to alter NOx to nitrogen, carbon dioxide and water. In order to control the performance of the reductant system, the powertrain control module (PCM) utilizes the reductant quality sensor. The code P206A is stored, whenever the sensor transmits an impractical signal.

Do you experience a sinking feeling in the pit of your stomach when the P206A check engine light flashes on? Often, as we know that the light denotes a costly problem like a damaged catalytic converter (although things can be minor at times, like an open gas cap). Most of the times, the flashing light means that you’ll be visiting the dealer to find the error for getting that light off.

What causes this problem with the Reductant Quality Sensor Circuit?

• The harness in the reductant quality sensor disconnected or short circuited
•  A weak electrical connection running in the reductant quality sensor circuit
• A malfunctioning reductant quality sensor

1. Reductant sensor - Is there a fault in your reductant sensor? It should be noted that a lot of issues can arise due to a faulty reductant sensor. An illuminated check engine light and reduced fuel efficiency are likely to accompany a malfunction in the reductant sensor. Tune into Parts Avatar, your one stop destination, to get your new reductant sensor.
2. Powertrain control module - Wishing to combat an error code P206A? A damaged powertrain control module acts as a huge obstacle in overcoming the problems caused by the error code P206A. In addition to the error code, the driver will notice problems with the overall drivability. Visit Parts Avatar for your new PCM now. What are you waiting for? We are just a click away!
3. Diesel exhaust fluid pump - Having problems due to a defective diesel exhaust fluid pump? See the error code P206A? Well, other than the error code, the driver will observe a lot of problems with the DEF equipments. So changing your malfunctioning diesel exhaust fluid pump can be one of the wisest decisions in order to avoid problems. Log into Parts Avatar now to grab amazing deals!
4. Reductant system parts - Having problems with the reductant system parts? Don’t you worry, Parts Avatar has it all. A faulty reductant system parts could end up being the root cause behind the error code P206A and problems related to the PCM programming too. Change or repair now!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P206A here:

Common Symptoms

• At times, the DPF regeneration may not happen

Here are some ways with the help of which you will be able to correct the OBD code P206A:

• Repair or replace a damaged reductant quality sensor immediately
• Make sure you mend or restore the open or short circuited harness in the reductant quality sensor circuit
• Fix a bad electrical connection running in the reductant quality sensor circuit

There is no need to be anxious as Parts Avatar – Car parts online is here to help you out! We have high quality sensor, PCM, DEF, implausible signal, reductant system, fuel injector, fuel injector harness, body control module, injection pump and a lot more for our precious customers.

We have listed here a few simple measures that should be taken in order to solve the error code P206A:

One can always observe banging or grinding noises due to broken or damaged engine mountings. Generally, mounting can be broadly divided into two major types: one in which it is centrally placed close to the bottom of the block and the other one is the one higher up the block which mount on to the inner wings or the frame members. Also, it should be noted that merely just replacing the sensor won't solve the underlying error, if the P206A OBD-II registers a sensor fault. The systems monitoring the sensor or the wirings to the sensor itself might be at fault triggering the error code P206A.

Common Mistakes When Diagnosing the P206A Code

Well, diagnosing an error code can often be a challenging task. So only for our customers, we have listed here a few common mistakes that should be avoided in order to prevent a misdiagnosis:

• A contaminated diesel exhaust fluid (DEF)
• A possible fault in the reductant quality sensor
• A failure in the selective catalytic reduction (SCR)
• Wiring issues in the system
