P219A on Nissan by model: symptoms, diagnosis and fix
On 2022+ Rogues equipped with the 1.5L KR15DDT variable-compression turbo engine, owners have reported rough idle, oil odor, hesitation, and check-engine lights tied to crankcase ventilation or related air-fuel control issues. These complaints are distinct from outright transmission concerns and appear in owner forums and complaint databases as the newer engine accumulated mileage. In some cases, the issue presents as drivability problems without obvious external leaks.
Common Symptoms
- Check engine light
- Rough idle
- Oil smell from engine bay
- Hesitation on acceleration
- Poor fuel economy
- Occasional stumble after startup
How to Fix
Scan for stored engine and fuel-trim faults, inspect the PCV system and hoses for restriction or leakage, and check for intake tract leaks or oil contamination. Depending on findings, repair may involve replacing the PCV-related components, updating ECM calibration if applicable, cleaning fouled intake components, and verifying fuel trims and idle quality after repair.

Frequently asked questions
What does P219A mean on a Nissan?
P219A stands for "Bank 1 Air/Fuel Ratio Imbalance." This code means the engine computer detected an air/fuel ratio imbalance among the cylinders on Bank 1, the bank containing cylinder #1. The computer compares oxygen sensor data with small variations in crankshaft speed to detect when individual cylinders are running noticeably richer or leaner than the others. An imbalance points to one or more cylinders not receiving the correct fuel or air. It can cause rough running, hesitation, and increased emissions, and over time may lead to a misfire if left unaddressed. On Nissan it is documented across 1 model: Rogue.
What are the most common causes of P219A?
The most common causes of P219A are: Dirty or leaking fuel injector on one cylinder, Vacuum leak affecting specific cylinders, Faulty air/fuel ratio or oxygen sensor, Low or uneven fuel pressure, Intake manifold gasket leak, Carbon-fouled or weak spark on a cylinder, Uneven compression among cylinders. The specific cause varies by vehicle.
How much does it cost to fix P219A on a Nissan?
Published repair estimates on Nissan range from $200 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
