Code P2191 KIA Description
When the diagnostic trouble code P2191 appears on a Kia vehicle, it indicates that the engine is running too lean at higher loads on bank 1. This means that there is an imbalance in the air-fuel mixture, with more air entering the combustion chamber than necessary, leading to a lean condition. This can result in decreased engine performance, reduced fuel efficiency, and potential damage to the engine over time if not addressed. The underlying cause of this issue could be related to problems with the fuel delivery system, oxygen sensor, intake system leaks, or issues with the engine control module.
Common Causes of P2191 KIA
- Faulty oxygen sensor
- Vacuum leaks in the intake system
- Clogged fuel injectors
- Dirty or failing mass airflow sensor
- Issues with the engine control module
Symptoms of P2191 KIA
- Rough idling or stalling
- Decreased engine power
- Engine misfires
- Poor fuel economy
- Illumination of the check engine light
How to Fix P2191 KIA
- Scan the vehicle's computer to confirm the P2191 code and identify the specific cause.

Frequently Asked Questions about P2191 KIA Code
1. What does the OBDII code P2191 mean on a KIA?
P2191 indicates that the engine's fuel system is running too lean on Bank 1 during higher load conditions, meaning there is too much air and not enough fuel in the mixture.
2. What are the common symptoms of P2191 in a KIA?
Symptoms include reduced engine performance, hesitation during acceleration, rough idling, poor fuel economy, or the Check Engine Light illuminating.
3. What causes the P2191 code in a KIA?
Common causes include a vacuum leak, a faulty mass airflow (MAF) sensor, a clogged fuel injector, low fuel pressure, or an exhaust leak upstream of the oxygen sensor.
4. Can a dirty air filter trigger the P2191 code on a KIA?
While rare, a severely clogged air filter can restrict airflow and contribute to a lean condition, but it is not a primary cause.
5. How do I diagnose the P2191 code on my KIA?
Start by inspecting for vacuum leaks, checking the MAF sensor for contamination, testing fuel pressure, and inspecting the oxygen sensor and exhaust system for leaks or damage.
6. Is the P2191 code safe to drive with?
Driving with a P2191 code for an extended period can damage the engine or catalytic converter, so it’s recommended to address the issue promptly.
7. How do I fix the P2191 code on a KIA?
Repairs may include fixing vacuum leaks, cleaning or replacing the MAF sensor, replacing faulty fuel injectors, or repairing exhaust leaks.
8. Can a bad fuel pump cause a P2191 code in a KIA?
Yes, a failing fuel pump can result in low fuel pressure, which may cause the engine to run lean and trigger the P2191 code.
9. What tools are needed to troubleshoot the P2191 code on a KIA?
You’ll need an OBDII scanner, a fuel pressure gauge, and possibly a smoke machine to detect vacuum leaks.
10. Can a software update fix the P2191 code in a KIA?
In some cases, a reflash or software update from the manufacturer can resolve fuel mixture issues if the problem stems from incorrect ECU programming.

I had the dealer check this out for me when i was having the oil changed in my 2014 KIA Sorento. Cost me $90.00 to have them tell me that my wife put E85 gas in.

I have a CNG kit installed and i have this code on my Kia Sportage GT 2016.Is that OK?

This code is for insufficient fuel under high load conditions. The suggestions that it could be caused by a leaking fuel injector or fuel pressure regulator or high fuel pressure is contrary. These "causes" for the most part will result in a rich condition.
