P2192System Too Rich at Higher Load (Bank 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Check engine light on
- Increased fuel consumption
- Fuel smell or dark exhaust under load
- Likely causes
- 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
- RareFuel pressure above specification
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
