What P2192 means
P2192 is the rich-side limit of the bank 1 trim in the upper load zone: the controller has pulled as much fuel as it may and the front sensor still reports excess fuel. Typical sources grow with demand, such as an air mass sensor reading high, fuel pressure above specification, or injectors that over-deliver or drip at high rail pressure; on direct-injection engines a leaking high-pressure injector is a prime suspect. Kia documents the code by name: bulletin ENG 146 (2015) lists P2192 with P2188 and other codes on 2012 to 2014 Rio and Soul with the 1.6 GDI engine and cures it with an ECM software upgrade rather than parts. GM handles the same load range as P2178 with a lower factor limit of 0.78. Expect higher consumption and possibly a fuel smell; P2188 is the idle counterpart, P2178 the off-idle one.
P2192 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P2192
- Check engine light on
- Increased fuel consumption
- Fuel smell or dark exhaust under load
Common causes of P2192
- PossibleECM calibration issue covered by a software update (e.g. Kia 1.6 GDI)
- PossibleAir mass sensor reading too high
- PossibleInjector leaking or over-delivering at high rail pressure
- Less likelyFuel pressure above specification
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2192 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1 | Area: fuel and air metering. |
| 92 | The exact fault in that area. |
What to do next
- Note P2192 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2192
What does P2192 mean?
P2192 means "System Too Rich at Higher Load (Bank 1)". P2192 is the rich-side limit of the bank 1 trim in the upper load zone: the controller has pulled as much fuel as it may and the front sensor still reports excess fuel. It is a generic code, so it means the same on every make.
Is it safe to drive with P2192?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2192 fail an emissions test?
Yes, it can. P2192 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2192 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2192 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
