P0507 on Chevrolet
Idle Air Control System RPM Higher Than Expected
P0507 on Chevrolet vehicles indicates idle air control system rpm higher than expected. Au7o has documented this code across 1 Chevrolet model — most commonly on Sonic. This code means the engine is idling faster than the computer's target idle speed, typically by a set margin such as 200 RPM above commanded. The engine control module manages idle by metering a small amount of air around the throttle plate (via an idle air control valve or electronic throttle), and when it can't bring the RPM down to target it flags this code. The most common real cause is unmetered air sneaking into the intake — a vacuum leak — that the computer can't compensate for. It generally indicates extra air entering the engine or a problem with the idle/throttle control system. Typical repair costs on Chevrolet range from $150 to $500, depending on the specific model and root cause.
Common Causes of P0507
- •Vacuum or intake air leak (hoses, gaskets, intake boot)
- •Dirty or sticking throttle body or throttle plate
- •Faulty or stuck idle air control valve
- •Leaking intake manifold or throttle body gasket
- •Stuck-open PCV valve or cracked PCV hose
- •Dirty mass airflow sensor giving false readings
- •Failing throttle position sensor
- •Leaking brake booster or its vacuum hose

Chevrolet Sonic(1 issue)
- 1.4L Turbo PCV Valve Cover Diaphragm Failure2012-2020
The 1.4L turbocharged Ecotec engine in the Sonic shares the notorious PCV system failure with the Chevrolet Cruze. The PCV regulator diaphragm integrated into the valve cover ruptures, causing massive vacuum leaks. Additionally, the intake manifold check valve (small red/orange valve) fails, compounding the issue. This affects virtually all 1.4T Sonics eventually, typically between 50,000-100,000 miles.
