Causes of the P0507 Code

The most common cause of the P0507 code is a dirty or faulty Idle Air Control valve. The IAC valve is located in the throttle body, and it controls the amount of air that bypasses the throttle plate. When the IAC valve is dirty, it can get stuck, which can cause the engine to idle too high or too low. A faulty IAC valve can also cause the engine to stall.

Other causes of the P0507 code include:

  • A vacuum leak in the intake manifold
  • A faulty throttle position sensor
  • A faulty MAP sensor
  • A faulty PCM

Symptoms of a Malfunctioning IAC System

The symptoms of a malfunctioning IAC system can vary depending on the underlying cause. However, some common symptoms include:

  • Rough idle
  • Stalling
  • High idle speed
  • Low idle speed
  • Poor fuel economy
  • Check engine light

How to Fix the P0507 Code

If you’re seeing the P0507 code, the first step is to clean the IAC valve. To do this, you will need to remove the IAC valve from the throttle body and clean it with a carburetor cleaner. Once the IAC valve is clean, reinstall it and see if the code goes away.

If cleaning the IAC valve does not fix the problem, you may need to replace the IAC valve. To do this, you will need to remove the IAC valve from the throttle body and install a new one. Once the new IAC valve is installed, clear the codes from the PCM and see if the code comes back.

If replacing the IAC valve does not fix the problem, you may need to have the PCM reprogrammed. The PCM is the computer that controls the engine, and it may need to be reprogrammed to recognize the new IAC valve.
