P0104 2019 Ford F150 Code - Mass Or Volume Air Flow Sensor 'A' Circuit Intermittent
Quick Answer
The P0104 diagnostic trouble code (DTC) for the 2019 Ford F150 indicates a problem with the Mass or Volume Air Flow (MAF/VAF) sensor circuit intermittently. Common causes include Dirty or contaminated MAF sensor: Dust, debris, or oil buildup on the MAF sensor can interfere with its readings, Faulty wiring or connections: Loose or damaged wiring connections between the MAF sensor and ECM can disrupt the signal, Air intake leaks: Any leaks in the air intake system can affect the MAF sensor's readings, leading to incorrect air-fuel mixture. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0104 2019 Ford F150 Description
The P0104 diagnostic trouble code (DTC) for the 2019 Ford F150 indicates a problem with the Mass or Volume Air Flow (MAF/VAF) sensor circuit intermittently. The MAF sensor is a crucial component that measures the amount of air entering the engine to determine the correct air-fuel mixture for combustion. When this sensor malfunctions or detects intermittent issues, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions. This code specifically points to a problem in the circuit that connects the MAF sensor to the vehicle's Engine Control Module (ECM), causing irregular readings or signal disruptions.
Common Causes of P0104 2019 Ford F150
- Dirty or contaminated MAF sensor: Dust, debris, or oil buildup on the MAF sensor can interfere with its readings.
- Faulty wiring or connections: Loose or damaged wiring connections between the MAF sensor and ECM can disrupt the signal.
- Air intake leaks: Any leaks in the air intake system can affect the MAF sensor's readings, leading to incorrect air-fuel mixture.
- ECM issues: A malfunctioning ECM can also cause intermittent problems with the MAF sensor circuit.
- Environmental factors: Extreme temperatures or humidity levels can impact the MAF sensor's performance over time.
Symptoms of P0104 2019 Ford F150
- Rough idling or stalling: The engine may experience rough idling or even stall unexpectedly due to incorrect air-fuel mixture.
- Reduced acceleration: The vehicle may struggle to accelerate smoothly or feel sluggish when accelerating.
- Poor fuel economy: A faulty MAF sensor can result in decreased fuel efficiency, leading to more frequent trips to the gas station.
- Illuminated Check Engine Light: The Check Engine Light may illuminate on the dashboard to indicate a problem with the MAF sensor circuit.
- Engine misfires: The engine may misfire or hesitate during acceleration, affecting overall performance.
How to Fix P0104 2019 Ford F150
- Inspect and clean MAF sensor: The MAF sensor should be inspected and cleaned using MAF sensor cleaner to remove any contaminants.
- Check wiring and connections: Ensure all wiring and connections related to the MAF sensor circuit are secure and free of damage.
- Repair air intake leaks: Any leaks in the air intake system should be repaired to prevent incorrect readings by the MAF sensor.
- Test and replace MAF sensor: If cleaning the MAF sensor does not resolve the issue, it may need to be tested and replaced if necessary.
- Reset ECM: After completing repairs, reset the ECM and clear the DTC to ensure the issue is resolved.
Cost to Fix P0104 2019 Ford F150
The typical cost for repairing a Mass or Volume Air Flow Sensor 'A' Circuit Intermittent issue on a 2019 Ford F150 can range from $100 to $400, including parts and labor. However, actual repair costs can vary depending on the location, dealership rates, and the specific diagnosis required. It's recommended to obtain quotes from local auto repair shops to get a more accurate estimate.
