What does P1506 mean?
Error Code P1506 is defined as Idle Air Control Overspeed Error. This code means that the engine idle is out of factory specification. 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.
Why does my car have a P1506 trouble code?
Air leaks into the engine AFTER the MAF has already metered the incoming air. So the oxygen sensor sees a very lean exhaust. Since the vehicle is at idle, the computer tries to reduce incoming air by shutting down the IAC. Once it commands less air and stills sees an idle that’s too high, it sets a P1506 trouble code.
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.
What causes a P1506 Ford to overspeed?
P1506 FORD Possible Causes 1 Faulty Idle Air Control (IAC) valve 2 IAC valve harness is open or shorted 3 IAC valve circuit poor electrical connection 4 Intake leaks 5 Stuck PCV Valve
How much does it cost to repair a P1506 Ford?
The cost to diagnose the P1506 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
