I have a 2002.5 ZX5. I recently purchased a pre 2000 intake manifold and I purchased a FC 65mm Throttle Body. Question I have is what setting should I put hooking up the TPS too since the manifold is an 00 but the car is an 02.5 I dont know wether it is using and 02 part or an 03 part. I was told the TPS should be set to whatever my ECU is, well is my ECU an 03 ECU or an 02? They changed alot of the parts on my ZX5 since it was the late model. I dont know how far that list goes as to what was changed though. Only thing for certain I know is the transmission, wheels and headlights were 03 versions.
Here is a picture of a TB with the positions in question. Although I doubt it would be a deciding factor since whoever know about this does not need a picture I would asume.



and here is mine

Is yours an ATX or 5 speed? You can test the voltage in each position but I forgot what the voltage is supposed to be. Do a search on tps voltage and you will find where it's supposed to at idle and WOT.

Its a 5 speed but how is voltage suppose to tell me which position to put the TPS sensor at? Where would I test it at? Its a 50/50 shot from the looks either the 00 5speed or the 03.

Take a multi meter, and do this. Try the first position according to your app on the TPS.

Turn your key on but do not start the car. Put the black probe into the neg post on the battery. Take the pos probe and stick into the white wire on your TPS. At "idle", you should get a reading between 0.4v - 0.9v. To test WOT, open up your TB all the way, and you should get a reading between 4.7v - 4.99v.

If you get those readings then you TPS is in the correct position. If you don't get these readings, move the TPS to a different position and do it again.

Here is a video of someone testing their voltage just to give you an idea.

check the exact date ur car was produced. go to a dealer and give them ur VIN, or, i don't remember if it is here, but check the inside part of the drivers door, there should be a decal there that gives you some info!!

The guys at my favorite shop know what they are doing and he let me know that he knows about the different positions and to use the volt meter. Should be installing them either monday or tuesday.

How can you install a intake manifold in 5 mins. Its impossible. If it were just the TB I would do it myself.

hehe, well if I bought one I need to install it.
Quoting myself from above "Should be installing them either monday or tuesday." Notice the word "them"?
Its cool man, 4 hour job for $170 is way below standard hourly rates. He quoted 4 hours since he thinks he might have to take the alternator off to get into the area. If he doesnt then it wont take that long.

Generally an IM install doesn't take more than an hour but it's all preference...whether you're comfy getting into that level of work or not.

I had my IM on and off for porting in 1 hour, you do not need to remove the altrenator. it is very easy and you can do it yourself to save $$$$

Well, considering when I looked at where it is on the engine and how I was going to get back there and not knowing where all the hook ups and things are at that need to be disconnected, I will happily have them do it for me while I watch and help. I have never done that kind of motor work before.
