P0507 fault code: what it means

P0507: Idle speed is higher than the engine computer wants.

Engine and gearbox (powertrain) · Minor

Usual causes, most likely first

vacuum leak
dirty throttle body
stuck idle air control valve

P0507 by make

Audi

Idle speed higher than expected. Usually an air leak or a dirty throttle body; on 2.0T check the crankcase breather valve.

Usual causes: vacuum leak (often PCV / breather valve on 2.0T); dirty or faulty throttle body (J338); throttle body wiring or plug

Haval

Idle speed higher than expected.

Usual causes: vacuum leak; dirty throttle body; idle relearn needed

Honda

Idle speed higher than expected. Common on CR-V and Accord; usually fixed by cleaning the throttle body and doing an idle relearn.

Usual causes: dirty throttle body or idle air control valve; idle relearn not done; vacuum leak

Mazda

Idle speed higher than expected on SkyActiv-G. Check vacuum hoses first.

Usual causes: vacuum hose off or split; purge solenoid valve stuck open; throttle valve stuck open; MAF reading wrong

MG

Idle speed higher than expected.

Usual causes: vacuum leak; dirty throttle body; idle relearn needed

Mitsubishi

Idle speed higher than the ECU wants.

Usual causes: vacuum leak; dirty throttle body; ECU needs idle relearn after cleaning or battery disconnect

Nissan

Idle speed higher than target. On Nissans usually after a throttle body clean, replacement or battery disconnect without the idle air volume relearn.

Usual causes: carbon build-up in the throttle body; idle air volume relearn not done after cleaning or battery disconnect; vacuum leak

Skoda

Idle speed higher than expected. Usually an air leak or a dirty throttle body; on 2.0T check the crankcase breather valve.

Usual causes: vacuum leak (often PCV / breather valve on 2.0T); dirty or faulty throttle body (J338); throttle body wiring or plug

Subaru

Idle speed is higher than the ECU wants. On Subaru usually a vacuum leak rather than the idle control itself.

Usual causes: vacuum leak (PCV hose, intake gaskets); dirty throttle body or idle air control valve; ECU needs idle relearn or software update

Volkswagen

Idle speed higher than expected. Usually an air leak or a dirty throttle body; on 2.0T check the crankcase breather valve.

Usual causes: vacuum leak (often PCV / breather valve on 2.0T); dirty or faulty throttle body (J338); throttle body wiring or plug

Before you clear it

Write the code down or photograph the scanner first. A code that comes straight back after clearing points to a fault that is still there. A car whose codes were cleared just before you arrived may be hiding one: the scanner's readiness monitors show "not ready" for a while after codes are cleared.
