P0507 KIA Code - Idle Air Control System RPM Higher Than Expected
Quick Answer
The Engine Control Module (ECM) 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 electric throttle control actuator. Common causes include Dirty throttle body, Electric throttle control actuator misadjusted or damaged, Faulty Electric throttle control actuator. 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 KIA Description
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the ECM 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.)
What are the Possible Causes of the DTC P0507 KIA?
- Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

Frequently Asked Questions about P0507 KIA Code
1. What are the common symptoms of OBDII code P0507 in a KIA?
- Common symptoms include high engine idle speed, engine stalling at idle, and increased fuel consumption.
2. What can cause the Idle Air Control System RPM to be higher than expected in a KIA?
- Possible causes include a dirty or faulty idle air control valve, vacuum leaks, a stuck throttle plate, or issues with the engine's computer.
3. How is the idle air control valve related to OBDII code P0507 in a KIA?
- The idle air control valve regulates the amount of air entering the engine at idle. If it malfunctions, it can cause the engine to idle at a higher RPM than expected, triggering the P0507 code.
4. What are some DIY repair tips for fixing OBDII code P0507 in a KIA?
- DIY repair tips include cleaning or replacing the idle air control valve, checking for vacuum leaks, inspecting the throttle body, and resetting the engine's computer.
5. Can driving with OBDII code P0507 in a KIA cause further damage to the vehicle?
- Driving with a high idle speed due to OBDII code P0507 can potentially lead to increased wear on engine components and reduced fuel efficiency if left unresolved for an extended period.
6. How can a mechanic diagnose OBDII code P0507 in a KIA?
- A mechanic can diagnose the issue by using a scan tool to read the code, performing a visual inspection of the idle air control valve and related components, and conducting tests to identify the root cause of the problem.
7. Is it safe to continue driving a KIA with OBDII code P0507?
- While it may be safe to drive in the short term, it is recommended to address the high idle speed issue associated with OBDII code P0507 promptly to prevent further damage and ensure optimal vehicle performance.
8. Will resetting the ECU resolve OBDII code P0507 in a KIA?
- Resetting the Engine Control Unit (ECU) may temporarily clear the code, but if the underlying issue causing the high idle speed is not fixed, the code is likely to reappear.
9. How long does it typically take to repair OBDII code P0507 in a KIA?
- The repair time can vary depending on the exact cause of the high idle speed. Simple fixes like cleaning the idle air control valve may take a short time, while more complex issues could require more extensive repairs.
10. Can a high idle speed due to OBDII code P0507 affect the KIA's emissions?
- Yes, a high idle speed can impact emissions by causing the engine to run inefficiently, potentially leading to increased emissions of pollutants such as carbon monoxide and hydrocarbons.
