1. Fault Overview
- Fault Code: P011E
- SPN-FMI: E000110-10
- Check Engine Lamp: ON
- Effect: Mild torque reduction (Torque Reduction 1)
Possible Causes:
- Thermostat malfunction (stuck open or damaged)
- Electrical issues, such as:
- Faulty coolant temperature sensor
- Damaged sensor connector
- Wiring harness issues between sensor and ECU
- ECU-related problems:
- Faulty ECU
- Damaged ECU connector
2. Component Location
3. Conditions Required to Run Diagnostic
The ECU will begin checking for this fault under the following conditions:
- Engine has been running for at least 120 seconds
- Coolant temperature at engine start is below 30°C
- Engine speed exceeds 1300 RPM
4. Conditions for Setting the Fault Code
The P011E fault code is triggered when the coolant temperature fails to increase as expected under the following restricted conditions:
Example:
If coolant temperature fails to rise by at least 5°C from a starting temperature of 0°C within 1000 seconds, the code will be set.
5. Conditions for Clearing the Fault Code
The fault code will automatically clear when the system detects the coolant temperature rises appropriately under the same restricted conditions (i.e., above the required threshold).
6. Troubleshooting Checklist
Conclusion
The P011E fault typically points to a coolant heating issue caused by either a mechanical fault (like a thermostat) or electrical signal inconsistencies. Careful step-by-step troubleshooting is essential to avoid unnecessary part replacements.
