P0507: Idle Air Control System RPM Higher Than Expected
11 vehicles · 9 makes · $30-$2,200 repair
Most Reported On
P0507 is an OBD-II diagnostic trouble code meaning “Idle Air Control System RPM Higher Than Expected.” 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. This code is most commonly reported on 2012-2020 Chevrolet Sonic, 2007-2014 MINI GP, and 2022-2024 Cadillac CT4 (V Blackwing, V-Series Blackwing), plus 8 other vehicles, with repair costs ranging from $30 to $2,200.
