How To Reset Exhaust Fluid Quality Poor

Introduction

Exhaust Fluid Quality Poor is an error message that may appear on your vehicle’s dashboard. This message is related to the selective catalytic reduction (SCR) system, which helps reduce harmful emissions in diesel vehicles. When the exhaust fluid quality is poor, it means that the diesel exhaust fluid (DEF) may be contaminated or the SCR system is not functioning properly. In this article, we will discuss how to reset the exhaust fluid quality poor message and troubleshoot potential causes.

1. Check the DEF Level

The first step in resetting the exhaust fluid quality poor message is to check the DEF level in your vehicle. The DEF tank should have enough fluid for the SCR system to function properly. Follow these steps to check the DEF level:

  1. Locate the DEF tank in your vehicle. It is usually found near the fuel tank.
  2. Remove the DEF tank cap.
  3. Check the fluid level using the DEF dipstick or the DEF level sensor if your vehicle has one.
  4. If the DEF level is low, refill it with fresh DEF fluid. Make sure to use a high-quality DEF fluid that meets the manufacturer’s specifications.

2. Check for DEF Contamination

If the DEF level is sufficient, the next step is to check for DEF contamination. Contaminated DEF can trigger the exhaust fluid quality poor message. Follow these steps to check for DEF contamination:

  1. Inspect the DEF fluid for any discoloration, sediment, or unusual odor. Clean DEF should be clear and free from debris.
  2. If you notice any contamination, flush the DEF system and refill it with fresh DEF fluid.
  3. It is recommended to drain and replace the DEF filter if contamination is detected.

3. Perform DEF System Reset Procedure

If the DEF level is sufficient and there is no contamination, the next step is to perform a DEF system reset procedure. This procedure allows the vehicle’s computer to reset the exhaust fluid quality poor message. Follow these steps to perform a DEF system reset:

  1. Start the vehicle and let it idle for at least 10 minutes to allow the DEF system to warm up.
  2. Once the vehicle is warmed up, turn off the engine and open the driver’s side door.
  3. Locate the DEF system reset button, usually located near the dashboard or in the engine compartment.
  4. Press and hold the DEF system reset button for about 3 seconds.
  5. The exhaust fluid quality poor message should now be reset. Start the vehicle again to confirm if the message reappears.

4. Check for Faulty Sensors or Components

If the exhaust fluid quality poor message persists even after performing the system reset, there may be faulty sensors or components in the SCR system. It is recommended to have the vehicle diagnosed by a qualified mechanic or dealership. They can perform a comprehensive scan to identify any error codes and determine the specific component causing the issue.

Common components that can cause the exhaust fluid quality poor message include:

  • DEF level sensor
  • DEF pump
  • DEF injector

If any faulty components are identified, they should be repaired or replaced as necessary to resolve the issue.

5. Regular Maintenance and Inspection

To prevent the exhaust fluid quality poor message from appearing in the future, it is essential to perform regular maintenance and inspection of the SCR system. Follow these tips to maintain the system’s efficiency:

  • Check the DEF level regularly and refill if necessary.
  • Use high-quality DEF fluid that meets the manufacturer’s specifications.
  • Inspect the DEF tank for any signs of damage or leaks.
  • Replace the DEF filter as recommended by the vehicle’s maintenance schedule.
  • Follow the manufacturer’s recommendations for driving conditions that ensure proper operation of the SCR system.

Conclusion

The exhaust fluid quality poor message is an important warning that should not be ignored. By following the steps mentioned in this article, you can reset the message and troubleshoot potential causes. It is crucial to maintain the SCR system properly to ensure optimal performance and reduce harmful emissions. If the issue persists, it is recommended to seek professional assistance for further diagnosis and repair.
