apparently the sensor for the 1989 turbo trans am, which is the actual vehicle with the 3 bar map sensor - not the grand national, has a new part number. i went to the dealer to get one and it was superceded with the following part number: 12223861. the connector number that was given on this site in another thread remained the same at 12085502. it is a three wire pigtail but all the wires are white. on the back of the sensor there are three letters C B A which i assume are the designations that are needed to be known for each wire. have to check nocab's post about the proper wiring.

 

this forum is acting up again!!!! i can't attach any pics of what i'm talking about. better remain calm - don't want get banned again.

ps if this posts w/out a hitch, i will be officially pissed. tried to attach the pics and after 5 miutes of waiting and waiting and waiting, it says document has no data. .... BULLSHIT!

Thanks for the updated part number. I'll have to write that down. What did both peices cost you if you don't mind me asking?

 

Mine just arrived from http://www.gmpartsdirect.com/. This place charges a lot for shipping, but it seems trustworthy and the parts prices were by far the cheapest I found. It is probably as good a deal as you are likely to get overall, even with the expensive shipping.

The new part number (12223861) has the same list price and price as the old number (16040749). I wonder what the difference is.

The connector (12085502) just looks like a standard 3 conductor WeatherPack connector to me. I think you can get them cheaper at AutoZone or something, but this one comes pre-wired and even includes some butt connectors, so perhaps it is worth it for the convenience.

I posted my invoice details here:

The total was $81.23 including shipping.

a customer of mine is a mechanic down the street at the local pontiac/gmc dealership. he got them at his cost.
the sensor lists at $98.15 --his cost $56.44
the connector lists at $28.76 --his cost $16.54

total w/tax $78.09

i guess it would have been the same as ordering from max's source, but i got it cheaper(na na na na naa na) anyways, good luck guys hope this is of help
