Top Makes and Models with DTC P0174

Driving with Code P0174—System Too Lean (Bank 2) is okay, but repairs should happen quickly to avoid damaging critical components, including the catalytic converter. This problem is common to Fords, Nissans, and Chevrolets, but other makes are vulnerable to code P0174-related issues.

Below is an expanded look at how a P0174 code impacts numerous makes and models. This breakdown covers occurrence rates by model year (2001-2023) and separates the frequency into low, moderate, or high levels. The worst of the worst are the five vehicles listed above.

What is the P0174 Code?

A mechanic using an OBD2 Scanner to fix a car — *This AI-generated image may not accurately represent all aspects of the intended subjects whether a person or object.*

The P0174 code indicates that the engine’s Bank 2 is running too lean, meaning there’s too much air or not enough fuel in the mixture. If left uncorrected, this can lead to poor performance, reduced fuel efficiency, and potential engine or catalytic converter damage. Common causes include a vacuum leak, a faulty mass airflow or oxygen sensor, an exhaust leak, a clogged fuel injector, or a problem with the fuel pressure regulator, fuel filter, or fuel pump. While you can drive briefly with this code, it’s best to diagnose and fix the issue promptly to avoid additional complications.

Read the complete article on P0174 Engine Code | System Too Lean (Bank 2) to discover the trouble areas to consider. This resource also offers tips on diagnosing the problem and what a DIYer can do to tackle a P0174 code independently (and when not to).

Top Models for P0174 Codes

Here’s a look at the makes and models most likely to have P0174 codes, according to FIXD sensor data. The absence of a model year ranking indicates no P0174 code was detected among the analyzed years, insufficient data, or the model wasn’t in production.
