P219DCylinder 2 Air-Fuel Ratio Imbalance
- 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
- P219D singles out cylinder 2. On engines with two banks, whether cylinder 2 sits on bank 1 or bank 2 depends on the maker's numbering, which decides whether P219A or P219B may appear alongside. Bulletins show three very different outcomes. Kia replaced the high-pressure injector and its clip plus the high-pressure and crossover fuel pipes on 2022 Carnival models with the 3.5 GDI V6 when any of P219C to P21A1 had set. Hyundai fixed P219C to P219F on the 2018 Sonata 2.0 turbo with ECM and TCM software and noted that drivers feel nothing. Stellantis found a charge-air cooler with a loose crimp on the 2025 RAM 1500 3.0 Hurricane, which set P219D among other cylinder codes along with a whistling noise and reduced boost. A real cylinder 2 fault is confirmed with an injector balance test and a leak-down test.
- What you may notice
- Check engine light on
- Often no driveability change
- Reduced power or whistling noise if a charge-air leak is the cause
- Likely causes
- LikelyFaulty high-pressure injector at cylinder 2 (direct injection)
- PossibleCharge-air leak upsetting cylinder filling (e.g. RAM 3.0 Hurricane)
- PossibleDetection logic corrected by software update (e.g. Hyundai Sonata 2.0T)
- RareCompression loss at cylinder 2
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
