A rough idle when stopped on your 2016 Nissan Rogue combined with code P0507 indicates the engine is idling higher than expected. This high idle code, counterintuitively, often causes rough or hunting idle as the system struggles to maintain proper idle speed.
Understanding P0507
Code P0507 indicates the engine idle speed is higher than the expected range programmed into the computer. The ECU attempts to compensate, creating unstable idle that feels rough or surging. The cause is typically an air leak that bypasses the throttle body, making the computer unable to properly control idle.
Common Causes in 2016 Rogue
The Rogue's 2.5L engine commonly develops high idle from vacuum leaks at intake manifold gaskets, cracked or disconnected vacuum hoses, stuck-open IACV (idle air control valve), throttle body carbon buildup preventing full closure, leaking brake booster creating vacuum leak, and PCV system leaks.
Symptoms Beyond Rough Idle
P0507-related rough idle includes RPM bouncing between 500-1200 at stop, car seeming like it wants to move forward in drive, surging or hunting idle, occasionally stalling when coming to a stop, and possible lean condition codes accompanying P0507.
Diagnostic Approach
Start with a smoke test to identify vacuum leaks - this is the most common cause. Inspect all vacuum hoses, especially small lines to sensors and the brake booster. Check throttle body for carbon deposits and clean if needed. Test IACV operation. Listen for hissing sounds that indicate air leaks.
Common Repairs
Many P0507 issues resolve with vacuum leak repair - replacing cracked hoses or tightening loose connections. Throttle body cleaning helps if carbon buildup is present. IACV replacement may be needed if it's stuck. Intake manifold gasket replacement addresses gasket-related leaks. Address all leaks for proper idle.
