P0507 – Meaning, Causes, Symptoms, & Fixes

What Does P0507 Mean?

The P0507 code is triggered when the Engine Control Module (ECM) detects that the idle control system is operating outside of the specified rpm range. Once this is detected, the engine goes into a safe mode triggering the P0507 code.

P0507 Symptoms

  • Check Engine Light
  • Harder to start engine
  • Rough engine idle

P0507 Causes

  • Faulty Idle Air Controller (IAC) Valve
  • Intake air leak
  • Faulty power steering pressure switch
  • Faulty electric throttle control actuator
  • Carbon buildup on the throttle body

Code P0507 Severity – Low 

This trouble code will not prevent your vehicle from driving, the most common results are fluctuations in your vehicle while running idle. However, this can lead to increased problems with your vehicle running overtime.

Code P0507 Common Diagnosis Mistakes

Prematurely replacing the power steering pressure switch before attempting to visually inspect and clean the carbon buildup in the idle air valve and throttle body.
