On the 2002 Ford F150, the P1507 is a fairly straight forward code pointing to a fault with the Idle Air Control (IAC) Valve. Inspect the air duct tubes for any cracks, holes or loose/missing connections. Visually inspect the electrical connector to the IAC for any loose, broken or damaged wires. Inspect the throttle body for any binding, build-up or air leaks. If the visual inspection checks ok, replacing the IAC Valve should solve the problem. You can find the IAC located on the top, driver’s side, mounted to the side of the throttle body. Sometimes the IAC Valve can be cleaned with the use of some throttle cleaner and a toothbrush. Try to get as much carbon build-up out of the valve body and piston. If the cleaning does not solve the problem or the problem returns after a short while, then the IAC Valve will need to be replaced. Remember to use a new gasket and to make sure that both mounting surfaces are thoroughly clean and free of any debris. Any air leaks here will result in engine performance issues.
