What P219D means
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.
P219D at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P219D
- Check engine light on
- Often no driveability change
- Reduced power or whistling noise if a charge-air leak is the cause
Common causes of P219D
- Most 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)
- Less likelyCompression loss at cylinder 2
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P219D 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. |
| 9D | The exact fault in that area. |
What to do next
- Note P219D 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 P219D
What does P219D mean?
P219D means "Cylinder 2 Air-Fuel Ratio Imbalance". P219D singles out cylinder 2. It is a generic code, so it means the same on every make.
Is it safe to drive with P219D?
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 P219D fail an emissions test?
Yes, it can. P219D 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 P219D to fix?
Difficulty: medium. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P219D 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.
