This summary uses the existing diagnostic information shown in full below.
This code means the car's computer thinks the engine isn't getting enough fuel when it's idling, which is like when the car is on but not moving.
The P054E code is triggered when the engine control module (ECM) detects that the amount of fuel being delivered to the engine at idle is less than what it expects.
The ECM monitors the idle control system to ensure the engine receives the appropriate amount of fuel to maintain a stable idle speed. If the fuel quantity is lower than expected, it may indicate a problem with the fuel delivery system or a sensor providing incorrect data.

Engine Performance
• Avoid driving the vehicle until the issue is diagnosed.
• Consult with a professional mechanic for accurate diagnosis.
Check if your vehicle is still under warranty for engine components.
This code has been more prevalent in vehicles with high mileage or those that have missed regular maintenance.
Moderate – While the vehicle may still be drivable, it can lead to more serious engine issues if not addressed promptly.
Ignoring this code can lead to increased emissions and potential safety risks if the engine stalls unexpectedly.
• Engine at operating temperature
• Vehicle in idle state
The idle air control valve is usually located on the throttle body of the engine.
Q: Can I drive with a P054E code?
A: It's not recommended to drive with this code active, as it can lead to engine stalling and other issues.
Q: How can I reset the P054E code?
A: You can reset the code using an OBD-II scanner, but it's important to fix the underlying issue first.
