For those who own a Ford vehicle, the Ford P200E Code is a critical diagnostic code that indicates a potential catalyst system over temperature (Bank 1) issue. This code is generated when the powertrain control module (PCM) detects an over temperature concern with either the exhaust gas temperature bank 1, sensor 2 (EGT12) or the exhaust gas temperature bank 1, sensor 3 (EGT13). If the EGT12 sensor temperature is greater than 830°C (1,526°F) or the EGT13 sensor temperature is greater then 950°C (1,742°F), the diagnostic trouble code (DTC) is set. When this occurs, the PCM illuminates the malfunction indicator lamp (MIL) and enters a torque reduction failure mode effects management (FMEM), which may result in engine shutdown. To help diagnose and fix this issue, there are a variety of causes and solutions to consider.
Causes and Solutions for Ford P200E Code
| Cause | Solution |
|---|---|
| Diesel particulate filter regeneration during heavy load and high ambient temperature conditions | Check the EGT12 and EGT13 PIDs. If no other DTCs are present, the system is operating correctly at this time. Advise the customer of the conditions that may cause this DTC. |
| Excessive amount of soot or ash in the diesel particulate filter | Diagnose other DTCs first. If no other DTCs are present, refer to the related service bulletins. |
| Damaged EGT12 sensor | Replace the EGT12 sensor. Then, check if the DTC is cleared. |
| Damaged EGT13 sensor | Replace the EGT13 sensor. Then, check if the DTC is cleared. |
| Coolant contamination of the exhaust system | Check for coolant leaks in the exhaust system and repair as needed. |
| Oil contamination of the exhaust system | Check for oil leaks in the exhaust system and repair as needed. |
1. Diesel Particulate Filter Regeneration
When the Ford P200E Code is triggered during heavy load and high ambient temperature conditions, it can be caused by diesel particulate filter regeneration. To diagnose this issue, it is important to check the EGT12 and EGT13 PIDs (parameter identification). If no other DTCs are present, the system is functioning correctly at this time. It is important to advise the customer of the conditions that may cause this DTC.
2. Excessive Amount of Soot or Ash
Another cause of the Ford P200E Code is an excessive amount of soot or ash in the diesel particulate filter. To diagnose this issue, it is important to diagnose any other DTCs first. If no other DTCs are present, it is important to refer to the related service bulletins.
3. Damaged EGT12 and EGT13 Sensors
Another potential cause of the Ford P200E Code is a damaged EGT12 or EGT13 sensor. If either of these sensors is damaged, it is important to replace them. Once replaced, it is important to check if the DTC is cleared.
4. Coolant Contamination
Coolant contamination of the exhaust system can also trigger the Ford P200E Code. To diagnose this issue, it is important to check for any coolant leaks in the exhaust system and repair as needed.
5. Oil Contamination
Finally, oil contamination of the exhaust system can also trigger the Ford P200E Code. To diagnose this issue, it is important to check for any oil leaks in the exhaust system and repair as needed.
Conclusion
The Ford P200E Code is a critical diagnostic code that indicates a potential catalyst system over temperature (Bank 1) issue. This code is generated when the powertrain control module (PCM) detects an over temperature concern with either the exhaust gas temperature bank 1, sensor 2 (EGT12) or the exhaust gas temperature bank 1, sensor 3 (EGT13). To diagnose and fix this issue, there are a variety of causes and solutions to consider. It is important to remember that improper diagnosis and repair of the Ford P200E Code can lead to further engine damage.
