P0507 2012 Ford Fusion Code - Idle Air Control System RPM Higher Than Expected
Quick Answer
The Powertrain Control Module (PCM) controls the engine idle speed to a specified level through the fine adjustment of the air, which is let into the intake manifold, by operating the Electronic Throttle Actuator Control (TAC). Common causes include Dirty Throttle Body, Faulty Electronic Throttle Actuator Control (TAC), Electronic Throttle Actuator Control harness is open or shorted. 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 P0507 2012 Ford Fusion Description
The PCM controls the Electronic Throttle Actuator Control so that the engine speed coincides with the target value memorized in the PCM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the PCM is determined by taking into consideration various engine conditions, such as during warming up, deceleration, and engine load (air conditioner, power steering, and cooling fan operation, etc.).
The Diagnostic Trouble Code (DTC) will set the idle speed is more than the target idle speed by 200 rpm or more.
What are the Possible Causes of the DTC P0507 2012 Ford Fusion?
- Dirty Throttle Body
- Faulty Electronic Throttle Actuator Control (TAC)
- Electronic Throttle Actuator Control harness is open or shorted
- Electronic Throttle Actuator Control circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)

Frequently Asked Questions about P0507 2012 Ford Fusion Code
1. What does the P0507 code mean on a 2012 Ford Fusion?
The P0507 code indicates that the Idle Air Control System's RPM is higher than the expected range, meaning the engine is idling too fast.
2. What are the common symptoms of a P0507 code?
Symptoms include a high idle speed, rough idling, poor fuel economy, possible stalling, and the Check Engine Light turning on.
3. What causes the P0507 code in a 2012 Ford Fusion?
Common causes include vacuum leaks, a dirty or faulty throttle body, a malfunctioning idle air control valve, a damaged PCV valve, or issues with the Engine Control Module (ECM).
4. Can a dirty throttle body cause the P0507 code?
Yes, a dirty or clogged throttle body can disrupt airflow and cause the engine to idle faster than expected, triggering the code.
5. How do I fix the P0507 code on my Ford Fusion?
Start by checking for vacuum leaks, cleaning the throttle body, inspecting the idle air control valve, and ensuring the PCV valve is functioning properly. If those don’t resolve the issue, further diagnostics may be needed.
6. Is it safe to drive with a P0507 code?
While the vehicle may still be drivable, a high idle RPM can lead to reduced fuel economy and potential damage to engine components if left unaddressed.
7. How do I check for vacuum leaks that could cause a P0507 code?
Inspect all hoses and connections for cracks, looseness, or wear. You can also use a smoke machine or carb cleaner to identify leaks around the intake system.
8. Can a faulty idle air control valve cause the P0507 code?
Yes, a malfunctioning idle air control valve can fail to regulate the engine's idle speed, resulting in a higher-than-expected RPM.
9. Will cleaning the throttle body clear the P0507 code?
If the throttle body is dirty and causing the high idle issue, cleaning it often resolves the problem and clears the code.
10. Do I need to reprogram the ECM after fixing the P0507 code?
In some cases, an ECM reset or relearn process may be necessary to recalibrate the idle speed after repairs are made. Check your vehicle’s repair manual for specific procedures.
