Understanding the Kia Soul EX P0171 Code

If you're a Kia Soul EX owner, you may have encountered the P0171 trouble code. This code indicates that your vehicle's engine control module (ECM) has detected a lean fuel mixture in the engine. In this article, we will explore what the P0171 code means, its causes, symptoms, and how Mavyn can assist you in resolving this issue.

What Does the P0171 Code Mean?

The P0171 code specifically refers to "System Too Lean (Bank 1)." This means that the engine is not receiving enough fuel or is getting too much air, leading to an imbalance in the air-fuel mixture. A lean mixture can cause various performance issues and may lead to engine damage if not addressed promptly.
