Error Code P206C: What It Means & What To Do?

<<See All OBD Codes

See the engine light? OBD error code P206C flashing? Can’t understand? No worries, we have got your back! Here’s how you can solve the error code P206C. This OBD-II code wiring issue is also determined as a reductant quality sensor circuit. It should be noted that the engine computer installed constantly controls the reductant catalyst system’ utilization of the DEF and it’s expertise in converting NOx to nitrogen, carbon dioxide and water. The powertrain control module employs the reductant quality sensor to regulate the functions and performance of the reductant system. Whenever an improbable signal is transmitted by the sensor, the error code P206C displays.

This information written here is pertinent for a major part as one can locate the reductant level sensors in the diesel powered vehicles with a DEF (diesel exhaust fluid) storage tank. The DEF urea solution is utilized in diesel engines while performing a number of essential functions of the ECM such as burning exhaust and decreasing the overall vehicle emissions. The total quantity of the DEF fluid level present in the storage tank is updated to the ECM by the reductant level sensor.

What causes this problem with the Reductant Quality Sensor Circuit Low?

• An unsound reductant level sensor
• Presence of a faulty fluid in DEF storage tank
• Electrical short circuit

1. Reductant Sensor - Facing the error code P206C? A defective reductant sensor can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P206C. In addition to this one is likely to observe rough engine signs and excessive black smoke emissions. Tune into Parts Avatar for supreme reductant sensor at economical prices.
2. Powertrain Control Module - Various erratic symptoms are likely to accompany along a damaged powertrain control module. The unit enables the system and transmission to work in tandem. So a faulty PCM can affect not only a few parts but the functioning of the entire system. Tune into Parts Avatar for top notch sets of PCM.
3. Diesel Exhaust Fluid Pump - Problems in the diesel exhaust fluid pump also at times triggers problems with the diesel particulate filter. So changing one can be one of the wisest decisions. Now get your new diesel exhaust fluid pump delivered right at your doorstep with Parts Avatar. Log in now so that you don’t miss any of our amazing deals.
4. Reductant System Parts - Fearing the error code P206C? Inferior quality reductant system parts can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P206C. Tune into Parts Avatar for supreme quality reductant system parts at economical prices.

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

A standard OBD-II trouble code scanner should be used to diagnose this trouble code P206C. The scanner will be used to check and view the freeze frame data and assess the code by a certified technician. The technician should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be restarted to see if the code pertains. If the code disappears it could likely be due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing the P206C Code

Diagnosing an error code can most of the times be a strenuous task. So only to save your hard-earned money and precious time, we have listed here a few common mistakes that should be avoided while diagnosing the code:

• A dirty diesel exhaust fluid (DEF)
• Faulty reductant quality sensor
• A jammed selective catalytic reduction (SCR)
• Wiring problems
