When a Ford vehicle’s engine is malfunctioning, the cause may be a Ford P220E Code. This code is a NOX Sensor Heater Control Circuit Range/Performance (Bank 1 Sensor 1) error. This error occurs when the nitrogen oxides bank 1, sensor 1 (NOx11) sensor does not reach the required operating temperature in a calibrated amount of time or when the NOx11 module is not able to maintain the required operating temperature after the NOx11 sensor is warm. Common causes of this issue include corrosion, incorrect connections, and a damaged NOx11 sensor. Diagnosis of this issue may indicate that the vehicle is operating in derate mode and may experience a loss of power. To remedy this problem, the related Service Bulletins SSM44458, SSM45013, and SSM45226 can be consulted.
Causes and Solutions for Ford P220E Code
| Cause | Solution |
|---|---|
| Corrosion | Check the electrical connections for corrosion and repair as necessary. |
| Incorrect connections | Verify that the connections are correct and make necessary adjustments. |
| Damaged NOx11 sensor | Replace the NOx11 sensor with a new one. |
| System warning message | Drive the vehicle until the system warning message is cleared from the instrument cluster message center. |
Corrosion
Corrosion of the electrical connections of the NOx11 sensor can be the cause of a Ford P220E Code. To determine if this is the cause of the problem, it is necessary to inspect the electrical connections for corrosion. If the connections are found to be corroded, they should be cleaned and repaired as necessary.
Incorrect Connections
Incorrect connections can also be the cause of a Ford P220E Code. To determine if this is the cause of the problem, it is necessary to verify that the connections are correct and make any necessary adjustments.
Damaged NOx11 Sensor
A damaged NOx11 sensor can also be the cause of a Ford P220E Code. To remedy this problem, it is necessary to replace the NOx11 sensor with a new one.
System Warning Message
If the system warning message is displayed in the instrument cluster message center, it is necessary to drive the vehicle until the warning message is cleared.
Conclusion
The Ford P220E Code is a NOX Sensor Heater Control Circuit Range/Performance (Bank 1 Sensor 1) error that can occur in Ford vehicles. Corrosion, incorrect connections, and a damaged NOx11 sensor can all be causes of this issue. To remedy this problem, it is necessary to check the electrical connections for corrosion and repair as necessary, verify that the connections are correct and make any necessary adjustments, replace the NOx11 sensor with a new one, and drive the vehicle until the system warning message is cleared from the instrument cluster message center. With the correct diagnosis and the right solutions, the Ford P220E Code can be resolved.
