Top Makes and Models with DTC P0175

Chevrolets, Nissans, and Fords are most vulnerable to Code P0175—System Too Rich (Bank 2), but other makes and models are no strangers to this problem. Short-term driving with this code is usually okay. However, delaying repairs can affect safety and engine performance and risk expensive repairs.

Code P0175-related issues impact vehicles from a wide array of manufacturers—SUVs, trucks, and passenger cars are all vulnerable. FIXD sensor data reveal that vehicles most likely to experience a P0175 code are:

Below is an expanded look at how a P0175 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 P0175 Code?

Car Mechanic scanning a vehicle at a city street — *This AI-generated image may not accurately represent all aspects of the intended subjects whether a person or object.*

A P0175 code indicates that Engine Bank 2 is running rich, meaning there’s too much fuel mixed with air. This condition results from an excess of fuel or insufficient oxygen. The problem results from faulty sensors (MAF or oxygen), vacuum leaks, fuel system problems (bad injectors, pressure regulators, or filters), or exhaust damage.

While short-term (a week or so) driving is possible, prolonged operation with this code risks:

Engine damage from improper fuel mixture
Failed catalytic converter
Decreased fuel economy
Poor performance and rough running
Increased emissions
Potential stalling or hesitation

The severity depends on the underlying cause of the issue. Simple fixes like replacing a sensor are common, but fuel system issues may require professional diagnosis. Prompt repair prevents more expensive damage.

Top Models for P0175 Codes

Here’s a look at the makes and models most likely to have P0175 codes, according to FIXD sensor data. The absence of a model year ranking indicates no P0175 code was detected among the analyzed years, insufficient data, or the model wasn’t in production.
