P0507 Code - Idle Control System RPM Higher Than Expected

What Does P0507 Mean?

Is the fuel pump sometimes not priming when you turn the key to ON(II)? Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. The mechanical timing is also something that you should check, as we mentioned above. When you see P0507 engine fault code on your engine code reader this description will help you.

What are the common causes of P0507 ?

A carbon coked throttle body bore is by far the most common cause of this code. Other causes include shorted or open electrical circuits, a faulty idle air control valve, a large vacuum leak, or a bad PCM. PCM failure is rare.



How do you troubleshoot P0507 ?

If all testing has passed so far yet you still have the same code, check your scan tool and see if it can open and close the IMRC valve. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
