Causes Of High Exhaust Temp Light
When the high exhaust temp light comes on, it can be caused by fouling of the turbine side of the turbocharger. This can lead to lower airflow and charge air pressure, resulting in higher exhaust gas temperatures. When this happens, it is important to take action to prevent further damage. Regular maintenance and inspection of the turbocharger can help identify and address issues early on, preventing the high exhaust temp light from coming on. It’s also essential to ensure that the engine is operating within the specified temperature and pressure ranges. By addressing these issues promptly, you can keep the high exhaust temp light from coming on and maintain the efficiency and performance of your vehicle.

Significance Of Exhaust Light
When the high exhaust temperature light comes on in your vehicle, it is a crucial early warning of exhaust system irregularities. This warning light indicates that a fault code has been saved to your car’s computer, allowing you to take action before more damage occurs. The exhaust light serves as an indicator of exhaust-related problems, signaling the need for immediate attention to prevent further complications. Understanding the significance of this warning can help you address the issue in a timely manner, ensuring the proper functioning of your exhaust system.
Common Questions About High Exhaust Temp Light
When the high exhaust temp light comes on in your vehicle, it can be a cause for concern. There are a few common questions that people often have when they see this light. One question is whether the exhaust temp light comes on during regen. The answer is yes, it can come on during regen as the system works to clean the diesel particulate filter. Another common question is how long a regen usually takes. The duration of a regen can vary depending on various factors, but generally, it takes around 20-40 minutes. It’s important to note that when the light comes on, it’s recommended to drive at highway speeds and let the system perform an auto regen. Keeping the vehicle in the throttle as much as possible can help maintain proper exhaust temperatures. If you’re experiencing high exhaust temp, it may be due to fouling of the turbine side of the turbocharger, which can lead to lower airflow and higher exhaust gas temperatures.

Frequently Asked Questions On What To Do When High Exhaust Temp Light Comes On
What Do I Do If My Exhaust Temperature Light Comes On?
When the exhaust temperature light comes on, drive at highway speeds for auto regen. Maintain throttle to keep temperatures up.
What Causes High Exhaust Engine Temp?
Fouling of the turbine side of the turbocharger causes high exhaust engine temp due to: – Fouling of turbine causing bad turbocharger performance – Lower airflow and charge air pressure – Higher exhaust gas temperatures. Regular maintenance can prevent this issue.
What Does It Mean When The Exhaust Light Comes On?
When the exhaust light comes on, it indicates a potential issue with the exhaust system. This may require immediate attention to prevent further damage. Check for any fault codes stored in the vehicle’s computer and address the underlying problem promptly.
Frequent driving at highway speeds can help in performing an auto regen to manage the high exhaust temperature.
Does Exhaust Temp Light Come On During Regen?
The exhaust temp light may come on during regen. It is recommended to drive at highway speeds to let the system perform an auto regen without needing to stop and perform a parked regen. Keeping exhaust temperatures up by applying throttle as much as possible while driving helps.
Conclusion
When the high exhaust temp light comes on, it’s important to address it promptly to prevent damage to your vehicle. Checking for fouling in the turbocharger and understanding DPF regen procedures can help keep exhaust temperatures in check. Regular maintenance and immediate action upon seeing the light can ensure a smooth and efficient running of your vehicle.
