Intake heater relay

I have an e99 (5/98) and seem to have an intake heater relay next to GP relay. My truck came with a "cold weather" package. Anyone else have this set up? The relays look identical and I was also wondering what exactly the heater is? Is it more glow plugs or an actual heater of some kind? Thanks in advance.

it for preventing white smoke at idle when its cold.

its pretty useless there is a ton of parameters that have to be present for it to kick on.

most of us get a AIH delete plug and get rid of it, its just a restriction.

My baby girl is asleep on my lap and I'm waiting on her momma to get home from work... nothing better to do than dig up old threads!

Here's a pic of an AIH...



I would delete it and make sure you have a hi-idle tune... I use my 1200 rpm hi-idle a lot in the winter, but I never see -15.

Question AIH delete

I was just reading thru the threads and saw that the E99 didn't come With an AIH. Now this link says they do. Am I missing something here, or do some of the E99 come with them. My truck was built in August I believe.

The OP's account of an early '99 with possible AIH is the first I've heard of... would be nice if they could post some pictures of what they have.

The early 99s did not have an AIH. If the OP's truck has one, it's been added by swapping parts, or an engine transplant. If that's the case, it probably doesn't do anything since there was no provision for the PCM to activate it, nor will the wires be in the main harness. Even if the PCM was swapped and the appropriate wires added, it's probably never even turned on due to the parameters for its activation being so narrow.

Question on the intake of the E99. There is some type of sending unit in the middle of the Y between the cold air and hot air tubes. It has an couple of wires coming from it. So I am guessing that it is some type of sending unit. At first I thought it was an intake heater. Any one know what it is. Thanks. Ron

That is the MAT, manifold air temperature sensor.
