It is exactly what it says. There is a big heating element in the middle of the five way manifold on top of the motor. You might need to worry about it. If it just quit working it's no big deal, you don't need it anyways....but if the element is crumbling/breaking apart then the chance exists that it could push it's way into the engine.
Several of us have simply removed the heater and the wiring for it and installed a plug in it's place.

"To reduce white smoke during long idle periods at low ambient temperatures, the PCM will activate the intake air heater. Specific conditions must be present before the heater is activated: "
-ambient temperature must be below 0 deg C (32 deg F)
-engine oil temperature must be below 55 deg C (131 deg F)
-vehicle power must be between 11.8 and 15 volts
-parking brake must be applied on manual transmission vehicles
-the transmission must be on park or neutral on automatic transmission vehicles
-glow plugs must be off
I think it's completely useless, and it blocks approximatey 20% of the arflow through the manifold. Can't say that I've ever missed it in four years of running without it.

I am getting a DTC code PO-0541 - Manf Intake Air Heater Circ Low. What is this and do I need to worry about it?
Thanks,
