Idle position sensor
Anyone know where it's located on a 2001 5.4? Truck won't idle now that it's cold until it warms up. Thanks

It's not a sensor, it's an IAC (idle air control) valve and it's attached to the throttle body.

Pull it and clean it. Spray some WD-40 into it and work the plunger with a screwdriver till it moves freely. See if that helps.

Motorcraft IAC is $65.79 at rockauto.com, and a gasket is $1.11.

it could be the throttle position sensor also.

Mine went out and it wouldn't idle well plus the jacked the transmission all up.

It's on the throttle body. Easy fix.
