Understanding the Kia Soul P0174 Code

If you're a Kia Soul owner, you may have encountered the P0174 trouble code. This code indicates that your vehicle's engine control module (ECM) has detected a lean condition in the engine's air-fuel mixture on bank 2. In this article, we will explore what the P0174 code means, its causes, symptoms, and how Mavyn can assist you in resolving this issue.

What Does the P0174 Code Mean?

The P0174 code specifically refers to a "System Too Lean (Bank 2)" condition. This means that the engine is receiving too much air or not enough fuel, leading to an imbalance in the air-fuel mixture. The ECM monitors the air-fuel ratio using various sensors, and when it detects that the mixture is too lean, it triggers the P0174 code.
