Code P1112 2002 Ford F150 Description
The P1112 diagnostic trouble code (DTC) for a 2002 Ford F150 indicates an Intake Air Temperature Sensor Intermittent issue. The Intake Air Temperature (IAT) sensor is a crucial component of the engine's air intake system, responsible for measuring the temperature of the incoming air. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency. An intermittent fault with the IAT sensor can lead to incorrect temperature readings being sent to the ECM, resulting in poor engine performance, reduced fuel efficiency, and potential drivability issues.
Common Causes of P1112 2002 Ford F150
- Faulty Intake Air Temperature sensor
- Damaged or corroded wiring/connectors leading to the sensor
- Poor electrical connection at the sensor
- Intake air leaks affecting sensor readings
- ECM software or hardware issues
Symptoms of P1112 2002 Ford F150
- Check engine light illuminated on the dashboard
- Engine running rough or misfiring
- Decreased fuel efficiency
- Difficulty starting the engine
- Engine stalling or hesitation during acceleration
How to Fix P1112 2002 Ford F150
- Begin by locating the Intake Air Temperature sensor, typically located near the air filter housing or intake manifold.
- Inspect the sensor and its wiring for any visible damage, corrosion, or loose connections.
- If the sensor or wiring is damaged, replace the sensor and repair or replace any faulty wiring.
- Clear the DTC using an OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, further diagnosis may be required to check for ECM issues or other underlying causes.
Cost to Fix P1112 2002 Ford F150
The cost of repairing an Intake Air Temperature Sensor Intermittent issue on a 2002 Ford F150 can vary depending on the specific cause of the problem and the labor rates in your area.
