This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble figuring out how much fuel should be sent to the engine. It's like when you try to pour a drink but can't decide how much to pour.
The engine control module (ECM) is detecting an issue with the fuel pressure control system. The adaptive fuel volume calculation is not aligning with expected values for Bank 1.
P3284 indicates that the ECM has detected an implausible value in the adaptive fuel volume calculation for Bank 1. This could be due to a malfunction in the fuel pressure sensor, a problem with the fuel pump, or a fault in the ECM's programming or logic.
• Check Engine Light illuminated
• Poor engine performance

P3284 is a less common code, indicating specific issues with fuel pressure control systems in modern vehicles.
High – This issue can lead to poor engine performance and potential engine damage if not addressed promptly.
Driving with this code can lead to safety issues due to potential engine stalling. Address the problem as soon as possible.
• Engine running
• Vehicle at operating temperature
The fuel pressure sensor is typically located on the fuel rail near the engine.
