P0507 code definition

P0507 is a generic OBD2 diagnostic trouble code (DTC) referencing a fault within the idle control system. This code is related to P0505 and P0506.

What the P0507 code means

The P0507 code means the idle control system has excessively high RPM. The ECU has a specific rpm range the idle is allowed and when it is higher than expected the ECU sets the P0507 code. Once this code is triggered it puts the vehicle into a failsafe mode and the Check Engine Light is illuminated on the dashboard.

What causes the P0507 code?

  • Intake air leak
  • Faulty or clogged IAC valve
  • Carbon buildup on the throttle body
  • Faulty power steering pressure switch
  • Alternator that has failed

What are the symptoms of the P0507 code?

  • Check Engine Light being illuminated
  • High engine idle
  • Fluctuating idle
  • Vehicle hard to start
  • Rough idle

How does a mechanic diagnose the P0507 code?

  • Hooks up a scan tool to the vehicle's DLC port and check for any codes present.

  • Notes the DTC freeze frame data for use on the test drive and clears the codes.

  • Performs a test drive of the vehicle to duplicate the malfunction.

  • Performs a visual inspection and checks for any torn vacuum line or outside air leaks

  • Inspects the throttle body for excessive carbon buildup and proper opening and closing function

  • Uses a scan tool to check the RPM while the IAC and power steering pressure switch are tested

  • Tests the charging system

Common mistakes when diagnosing the P0507 code

Mistakes are made when simple items are overlooked due to not following steps in the proper order or not performing them at all. A few different systems are involved in the P0507 code and if one system is overlooked parts that are working properly may be replaced.

How serious is the P0507 code?

P0507 should not prevent the vehicle from driving to a safe location once the malfunction occurs. The idle fluctuations may cause the vehicle to have trouble running but in most cases the engine will not die.

What repairs can fix the P0507 code?

  • Replacing or cleaning the idle air valve
  • Repairing the intake air leak
  • Repairing the charging system
  • Cleaning the throttle body
  • Replacing the power steering pressure switch

Additional comments for consideration regarding the P0507 code

The idle air valve and the throttle body can build up excessive deposits of carbon over time usually over 100k miles. This buildup can cause issues with the operation of these parts by clogging them or stopping proper movement. A throttle body cleaner can be used to removed the carbon buildup.

Kenneth is clearly a first-rate mechanic. He thoroughly inspected our vehicle and found that the engine light was on because of a crack in the filler neck hose.
