P0507

What does P0507 mean?

Idle speed is higher than the computer commands.

Can I drive with P0507?

A steady check-engine light with the car otherwise behaving normally usually means you can drive carefully to get it diagnosed — but a flashing light, shaking, lost power, or a strong fuel smell changes that. When in doubt, treat it as more serious. See Can I Drive It? for a quick read on your exact symptoms.

Common symptoms

• Check engine light
• Idle too high or too low
• Stalling at stops
• Surging idle

Possible causes

Possible causes include — not “the part is definitely bad”:

• A vacuum leak
• A stuck idle-air or throttle control
• A throttle-body issue

What P0507 does not prove

It does not prove a single idle-control part has failed — vacuum leaks, throttle-body condition, or the control circuit can all upset idle.

What you can safely check

• Whether idle is high, low or surging
• Whether the light is steady or flashing
• For obvious disconnected hoses when safe

What a shop may check

An example diagnostic direction, not a guaranteed procedure:

• Scan tool and live idle and airflow data
• The idle-air or throttle control
• A check for vacuum leaks
• The throttle body condition

What not to do

• Don’t assume one idle part without checking for vacuum leaks
• Don’t keep driving if it stalls in traffic

Generic OBD-II guidance — manufacturer-specific codes and causes vary by make, so always confirm against your vehicle. A code identifies a system or condition; it does not, on its own, prove which part has failed.
