This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the way air is being controlled when the engine is cold. It's like when you try to blow up a balloon, but the air isn't going in the right way.
The code P06FE is triggered when the engine control module (ECM) detects an issue with the intake air flow control during a cold start condition in a diesel engine.
The P06FE code indicates that the ECM has identified a performance issue with the intake air flow control system during the engine's cold start phase. This system is responsible for managing the amount of air entering the engine to ensure optimal combustion and emissions control. A malfunction can lead to improper air-fuel mixture and inefficient engine operation.
• Check Engine Light is on
• Rough idling during cold start
• Decreased fuel efficiency
• Faulty intake air flow control valve
• Wiring issues or poor electrical connections
• Defective ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code
• Inspect the intake air flow control valve for damage
• Check wiring and connections for continuity
• Replace the intake air flow control valve
• Repair or replace damaged wiring
• Reprogram or replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance of the air intake system
• Ensure all electrical connections are secure
• Use high-quality diesel fuel
Engine Performance
• Do not ignore the Check Engine Light
• Get the vehicle inspected by a professional
• Avoid driving the vehicle until the issue is resolved
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been more prevalent in diesel engines with advanced emissions control systems introduced in the past decade.
Moderate – It is advisable to address this issue soon to avoid potential engine damage.
Driving with a malfunctioning air flow control system may result in increased emissions, which can be illegal in some areas.
• Engine must be cold
• Ambient temperature should be below 50°F
The intake air flow control valve is typically located near the air intake manifold of the engine.
Q: Can I drive with a P06FE code?
A: It's not recommended to drive with this code active as it may lead to further engine issues.
Q: How does the intake air flow control affect my engine?
A: It helps manage the air entering the engine for proper combustion, especially during cold starts.

Fitment Required · Vehicle-fitment part
Relevant for airflow, fuel-trim, and intake-metering faults after confirming the sensor is actually at fault.
Airflow and fuel-trim codes can involve the mass air flow sensor after proper diagnosis.
Verify the sensor design and fitment for your exact vehicle.
