P1507 2002 FORD F150 Code - Idle Air Control Under Speed Error
|P1507 2002 FORD F150 code possible causes
- Faulty Idle Air Control (IAC) valve
- IAC valve stuck closed
- IAC valve harness is open or shorted
- IAC valve circuit poor electrical connection
|How is the P1507 2002 FORD F150 code repair?
Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|P1507 2002 FORD F150 code tech notes
The P1507 code means that the engine idle is out of factory specification. 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.
If the problem persistss, the IAC valve may need to be replaced.
|What is the cost to diagnose the P1507 2002 FORD F150 code
The cost to diagnose the P1507 2002 FORD F150 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. Most auto repair shops charge between $75 and $150 per hour.
|When is the P1507 2002 FORD F150 code detected?
The P1507 code sets when the Powertrain Control Module (PCM) detects an engine idle speed that is less than the desired RPM.
|What are P1507 2002 FORD F150 code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|What is P1507 2002 FORD F150 code meaning?
The Idle Air Control Valve (IACV) valve assembly controls the engine idle speed and provides a dashpot function. The IAC valve assembly meters intake air around the throttle plate through a bypass within the IAC valve assembly and throttle body. The Powertrain Control Module (PCM
) determines the desired idle speed or bypass air and signals the IAC valve assembly through a specified duty cycle. The IAC valve responds by positioning the IAC valve to control the amount of bypassed air. The PCM
monitors engine RPM and increases or decreases the IAC duty cycle in order to achieve the desired RPM.
