P1507 2010 Ford Fusion Code - Idle Air Control Under Speed Error
Quick Answer
The P1507 code for a 2010 Ford Fusion indicates an "Idle Air Control Under Speed Error." This code is triggered when the Engine Control Module (ECM) detects that the engine idle speed is lower than expected and outside of the specified range. Common causes include Faulty idle air control valve: The IAC valve may be stuck open or closed, leading to idle speed errors, Vacuum leaks: Leaks in the vacuum system can disrupt the air-fuel mixture and affect engine idle, Dirty throttle body: Build-up of carbon deposits on the throttle body can restrict airflow and cause idle issues. 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 P1507 2010 Ford Fusion Description
The P1507 code for a 2010 Ford Fusion indicates an "Idle Air Control Under Speed Error." This code is triggered when the Engine Control Module (ECM) detects that the engine idle speed is lower than expected and outside of the specified range. The idle air control valve (IAC) is responsible for regulating the amount of air that enters the engine at idle, ensuring that the engine runs smoothly and maintains a consistent idle speed. When the IAC fails to operate properly, it can lead to erratic idle speeds, stalling, rough idle, and poor engine performance.
Common Causes of P1507 2010 Ford Fusion
- Faulty idle air control valve: The IAC valve may be stuck open or closed, leading to idle speed errors.
- Vacuum leaks: Leaks in the vacuum system can disrupt the air-fuel mixture and affect engine idle.
- Dirty throttle body: Build-up of carbon deposits on the throttle body can restrict airflow and cause idle issues.
- Malfunctioning throttle position sensor: A faulty TPS can send incorrect signals to the ECM, affecting idle speed.
- ECM issues: A problem with the Engine Control Module can result in incorrect idle speed control.
Symptoms of P1507 2010 Ford Fusion
- Rough idle: The engine may idle erratically, with fluctuations in RPM.
- Stalling: The engine may stall when coming to a stop or at idle.
- Poor acceleration: The vehicle may exhibit sluggish acceleration or hesitation.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard.
- Reduced fuel efficiency: The vehicle may experience decreased fuel economy due to inefficient engine operation.
How to Fix P1507 2010 Ford Fusion
- Diagnostic scan: Use an OBD-II scanner to retrieve the fault code and perform a comprehensive diagnosis of the idle air control system.
- Check idle air control valve: Inspect the IAC valve for proper operation and clean or replace it if necessary.
- Throttle body cleaning: Clean the throttle body to remove any carbon deposits that may be affecting airflow.
- Check for vacuum leaks: Inspect the vacuum hoses and connections for leaks and repair or replace as needed.
- Throttle position sensor inspection: Test the TPS for proper operation and replace if faulty.
Cost to Fix P1507 2010 Ford Fusion
The typical repair costs for addressing a P1507 code on a 2010 Ford Fusion can range from $100 to $500, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the cost of diagnostic scans, replacement of components such as the idle air control valve or throttle position sensor, and labor charges. It's important to note that actual repair costs can vary based on the location of the repair shop, the make and model of the vehicle, and the extent of the repairs needed. It's recommended to consult with a trusted mechanic or auto repair shop for a more accurate cost estimate based on the individual circumstances.
