P0507 on a Nissan: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

Drivable, but the engine idles too fast, which wastes fuel and makes low-speed driving feel odd.

What P0507 means on a Nissan

On a Nissan, P0507 means the engine is idling faster than the computer expects. Too much air is getting into the engine at idle, often from a vacuum leak or a dirty throttle body. The car still drives, but it idles high and uses more fuel.

Is P0507 common on Nissans?

P0507 shows up on Nissans like the Altima, Sentra, Rogue, and Pathfinder, usually on higher-mileage cars. Rubber vacuum hoses crack with age, and carbon collects in the throttle body and idle air control valve. A leaking PCV hose is another common trigger.

Commonly reported on: Altima, Sentra, Rogue, Pathfinder.
