The Ford Code P2297 is an error code that indicates that the rear heated oxygen sensor is out of range during deceleration. The powertrain control module uses this code to monitor the rich-to-lean switch of the oxygen sensor. When the measured value is slower than the threshold value, the oxygen sensor is not working as expected. This code can have various causes and solutions; understanding them is important to diagnose and troubleshoot the issue. This article will discuss the different causes and solutions of Ford Code P2297.

Causes and Solutions for Ford Code P2297
Cause | Solution |
---|---|
Faulty Oxygen Sensor | Replace the oxygen sensor |
Poor Electrical Connections | Check and clean the connections |
Faulty Exhaust System | Repair or replace the exhaust system |
Incorrect Oxygen Sensor | Install the correct oxygen sensor |
Faulty Oxygen Sensor
A faulty oxygen sensor is one of the most common causes of Ford Code P2297. The powertrain control module monitors the rich-to-lean switch of the oxygen sensor. If the measured value is slower than the threshold value, the PCM will trigger the P2297 code. If the oxygen sensor is faulty, it should be replaced.
Poor Electrical Connections

Another potential cause of Ford Code P2297 is poor electrical connections. The code can be triggered if the wiring or connectors to the oxygen sensor are corrupted or damaged. In this case, the connections should be checked and cleaned.
Faulty Exhaust System
A faulty exhaust system can also trigger Ford Code P2297. Exhaust leaks can cause the oxygen sensor to read incorrect values and trigger the code. If there is an exhaust leak, it should be repaired or the exhaust system should be replaced.
Incorrect Oxygen Sensor
Finally, an incorrect oxygen sensor can also trigger Ford Code P2297. If the wrong sensor is installed, it can activate the code. The faulty sensor should be removed, and the correct one should be installed to solve the issue.
Conclusion
Ford Code P2297 is an error code that is triggered when the measured value of the rear heated oxygen sensor is slower than the threshold value. It can have various causes and solutions, such as faulty oxygen sensors, poor electrical connections, an exhaust system, or an incorrect oxygen sensor. It is important to understand the various causes and solutions of Ford Code P2297 to diagnose and troubleshoot the issue.
