P0112 2015 Ford F150 Code - Intake Air Temperature Sensor 1 Circuit Low Input

Quick Answer

The P0112 diagnostic trouble code (DTC) for a 2015 Ford F150 indicates a problem with the Intake Air Temperature (IAT) Sensor 1 Circuit, specifically a low input signal. Common causes include Faulty IAT sensor: The sensor itself may be malfunctioning and providing incorrect temperature readings, Damaged wiring or connectors: Corrosion, fraying, or loose connections in the wiring harness can disrupt the signal, Intake air leaks: Air leaks near the sensor can affect temperature readings. 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 2015 Ford F150 Description

The P0112 diagnostic trouble code (DTC) for a 2015 Ford F150 indicates a problem with the Intake Air Temperature (IAT) Sensor 1 Circuit, specifically a low input signal. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the ECM detects a low input signal from the IAT sensor, it means that the temperature reading is lower than expected, which can lead to various performance issues.

Symptoms of P0112 2015 Ford F150

  1. Decreased fuel efficiency: The ECM may adjust the air-fuel mixture incorrectly, leading to poor fuel economy.
  2. Rough idling or stalling: Incorrect temperature readings can cause erratic engine behavior at idle.
  3. Engine hesitation or lack of power: The engine may not perform optimally due to inaccurate temperature data.
  4. Check Engine Light: The P0112 code will trigger the Check Engine Light on the dashboard.
  5. Reduced performance: The vehicle may feel sluggish or have difficulty accelerating.

How to Fix P0112 2015 Ford F150

  1. Diagnostic scan: Use an OBD-II scanner to retrieve the trouble code and confirm the issue.
  2. Inspect IAT sensor: Check the sensor for any visible damage or signs of malfunction.
  3. Test wiring and connections: Inspect the wiring harness for damage and ensure all connections are secure.
  4. Replace IAT sensor: If the sensor is faulty, replace it with a new one.
  5. Clear codes and test drive: Clear the DTC, reset the ECM, and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P0112 2015 Ford F150

The cost of repairing a P0112 code on a 2015 Ford F150 can vary depending on the location, parts needed, and labor rates.
