When it comes to deciphering Ford Code P219E, it can be a tricky endeavor. This code is defined as the cylinder three air-fuel ratio imbalance and is designed to detect minimal differences in the air-to-fuel ratio between cylinders. This diagnostic trouble code (DTC) is set when the minimal air-to-fuel ratio difference in cylinder 3 is greater than a calculated amount. To help diagnose and resolve this issue, it is important to understand the potential causes and solutions associated with the code.

Causes and Solutions of Ford Code P219E
| Cause | Solution |
|---|---|
| Leaking or contaminated cylinder three fuel injector | Replace the fuel injector and ensure proper sealing |
| External noise sources on the CKP circuit | Check the routing of the CKP sensor wiring harness |
| Low fuel pressure or running out of fuel | Check fuel pressure and add fuel as needed |
| Leaking EVAP purge valve | Replace the EVAP purge valve and ensure proper sealing |
Cylinder 3 Fuel Injector
Ford Code P219E can be caused by a leaking or contaminated cylinder three fuel injector. This will lead to an incorrect air-fuel ratio, as the injector is not correctly controlling the fuel flow. The fuel injector must be replaced, and the engine must be inspected for proper sealing to fix this issue.
External Noise Sources
External noise sources on the CKP circuit can also cause Ford Code P219E. This can interfere with the signal the crankshaft position sensor sends to the PCM, causing the air-fuel ratio to become unbalanced. To resolve this, it is important to check the routing of the CKP sensor wiring harness.

Low Fuel Pressure
Low fuel pressure or running out of fuel can also cause Ford Code P219E. The air-fuel ratio will become unbalanced when the fuel pressure is too low. To resolve this issue, the fuel pressure needs to be checked, and, if necessary, fuel added as needed.
Leaking EVAP Purge Valve
Lastly, a leaking EVAP purge valve can cause Ford Code P219E. The purge valve is part of the EVAP system, which controls the air-fuel ratio. To fix this issue, the EVAP purge valve must be replaced, and the engine needs to be inspected for proper sealing.
Conclusion
Ford Code P219E is a diagnostic trouble code set when the minimum air-to-fuel ratio difference in cylinder 3 is greater than a calculated amount. Understanding this code’s potential causes and solutions is essential for properly diagnosing and resolving the issue. Causes of Ford Code P219E include a leaking or contaminated cylinder three fuel injector, external noise sources on the CKP circuit, low fuel pressure or running out of fuel, and a leaking EVAP purge valve. Solutions for this code include replacing the fuel injector, checking the routing of the CKP sensor wiring harness, checking fuel pressure and adding fuel as needed, and replacing the EVAP purge valve. With the right knowledge and tools, Ford Code P219E can be properly diagnosed and resolved.
