What is the code for idle air control overspeed?
What is the code for idle air control overspeed?
We start with the code. DTC P1506 is “Idle Air Control Overspeed Error (see P0506)”. DTC P0506 is “Idle Air Control System RPM Lower Than Expected”. amckane July 5, 2016, 7:31pm #4 Update: Did more research, and most opinions pointed toward cleaning the throttle body.
How to relearn Mazda idle air control overspeed?
Disconnect the car battery, remove the valve, clean, re-install valve, and drive the vehicle for about 5 minutes with the headlights and A/C ON to get the idle relearned. Also, check for intake leaks or stuck PCV Valve.
What to do if your idle air control is not working?
Sometimes the Idle Air Control (IAC) may have carbon built up. Disconnect the car battery, remove the valve, clean, re-install valve, and drive the vehicle for about 5 minutes with the headlights and A/C ON to get the idle relearned. Also, check for intake leaks or stuck PCV Valve. If the problem persistss, the IAC valve may need to be replaced.
What causes IAC system overspeed error P1506?
PS the error code has always been “p1506 IAC system overspeed error”. A vacuum leak will also cause the “overspeed” error code. The only thing the computer knows is that there’s too much air getting into the engine and it’s causing it to idle too fast.
Error Code P1506 is defined as Idle Air Control Overspeed Error. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Ford.

What does the idle air control code P1506 do?
The P1506 code sets when the Powertrain Control Module (PCM) detects an engine idle speed that is greater than the desired RPM. The Idle Air Control Valve (IACV) valve assembly controls the engine idle speed and provides a dashpot function.
