What does P0507 mean on a Nissan?

On Nissan vehicles, the P0507 code indicates: PCM commanded idle RPM is lower than actual idle speed — engine idles faster than target.

Is it safe to drive my Nissan with a P0507?

You can drive for a short distance, but you should inspect your Nissan as soon as possible to avoid further damage.

P0507

Nissan Idle Air Control System RPM High

Specialized diagnostic report for Nissan owners dealing with the P0507 fault code.

Technician's Overview

🟡 SERVICE SOON

PCM commanded idle RPM is lower than actual idle speed — engine idles faster than target. When this code is triggered in a Nissan, the engine control module (ECM) has detected an issue with the Idle Control system.

Common Symptoms

High idle — 1,000–2,500 RPM at warm idle when in park in my Nissan
Engine surges and hunts at idle in my Nissan
Transmission clunk into Drive — higher than normal idle RPM at stop in my Nissan

Probable Causes

Vacuum leak (most common) — cracked intake boot, disconnected vacuum line
Dirty throttle body — carbon buildup preventing blade from seating
IAC (idle air control) valve stuck open
Throttle body actuator fault (electronic throttle — DBW vehicles)

Recommended Fixes for Nissan

Inspect intake boot for cracks, especially near throttle body clamps
Remove and clean throttle body with throttle body cleaner — do NOT use carburetor cleaner on MAF
Perform throttle body relearn procedure after cleaning (many GM/Toyota models require it)
Test IAC valve resistance (spec: 10–14 Ω typical); replace if out of spec
