Identifying the Culprit

Allow us to present a 2016 Jeep Cherokee 2.4L engine as a reference point for our discussion. The P2097 code commonly relates to the downstream oxygen sensor detecting a rich running system. Our diagnostic tool visually depicts the code and the subsequent challenges associated with it.

The downstream oxygen sensor is identified as a potential culprit. While a defective sensor is often to blame, we stress the importance of running comprehensive tests before jumping to conclusions. Our video detailing the testing process for the downstream oxygen sensor can guide you through this critical step.

However, a faulty catalytic converter is another primary suspect in triggering the P2097 code. A deteriorating catalytic converter can significantly impact your vehicle’s performance and lead to the emission of error codes.

Furthermore, a leaking fuel injector could disrupt the air-to-fuel ratio, leading to a rich running system. In addition to that, a malfunctioning fuel regulator, often integrated into the fuel pump assembly, can cause an imbalance in fuel pressure, consequently triggering the P2097 code.


We hope this comprehensive guide sheds light on the common triggers of the P2097 code in Jeep Cherokees. By familiarizing yourself with these potential issues, you’ll be better equipped to address them effectively, potentially saving both time and money.
