P0112 2000 Ford F150 Code - Intake Air Temperature Sensor Circuit Low Input
Quick Answer
The P0112 diagnostic trouble code (DTC) for a 2000 Ford F150 refers to the Intake Air Temperature (IAT) Sensor Circuit Low Input. Common causes include Faulty IAT Sensor: The sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM, Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the signal between the IAT sensor and the ECM, ECM Malfunction: A problem with the engine control module can also cause a low input signal from the IAT sensor. 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 P0112 2000 Ford F150 Description
The P0112 diagnostic trouble code (DTC) for a 2000 Ford F150 refers to the Intake Air Temperature (IAT) Sensor Circuit Low Input. This code indicates that the engine control module (ECM) has detected a lower than expected voltage signal from the IAT sensor. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for determining the air-fuel mixture and ignition timing. When the ECM receives a low input signal from the IAT sensor, it can lead to incorrect fuel and ignition settings, resulting in poor engine performance, reduced fuel efficiency, and increased emissions.
Common Causes of P0112 2000 Ford F150
- Faulty IAT Sensor: The sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
- Wiring Issues: Corrosion, damage, or poor connections in the wiring harness can disrupt the signal between the IAT sensor and the ECM.
- ECM Malfunction: A problem with the engine control module can also cause a low input signal from the IAT sensor.
- Air Intake Blockage: A blocked air filter or intake duct can affect the temperature of the incoming air, leading to erroneous readings from the IAT sensor.
Symptoms of P0112 2000 Ford F150
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Poor Fuel Economy: A malfunctioning IAT sensor can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Rough Idle: Incorrect air-fuel mixture can result in a rough or unstable idle when the vehicle is stationary.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to incorrect fuel and ignition settings.
How to Fix P0112 2000 Ford F150
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a visual inspection of the IAT sensor and wiring.
- Test the IAT Sensor: Check the resistance of the sensor at different temperatures to determine if it is functioning correctly.
- Inspect Wiring: Check for any damage, corrosion, or loose connections in the wiring harness and repair as necessary.
- Replace IAT Sensor: If the sensor is faulty, replace it with a new one and ensure proper installation.
- Clear DTC: Clear the DTC from the ECM memory using a scan tool and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0112 2000 Ford F150
The cost of repairing a P0112 code on a 2000 Ford F150 can vary depending on the cause of the issue. On average, the cost of replacing an IAT sensor ranges from $50 to $100, while the labor cost for diagnosis and repair can range from $100 to $200. Overall, the total repair cost for this issue may fall between $150 and $300. It's important to note that labor rates and part prices can vary based on location, the specific repair shop, and the availability of parts. It's recommended to obtain quotes from multiple auto repair shops to ensure a competitive price.
