so the car is rebuild

new trans, front sheetmetal

motor is original

1.check engine light-code 120 TPS

replaced and played with light stays on

2.a/c fan runs from key on allways

3.doesnt shut off right, roll's off ,dies slowly

runs good, trans seems good, i cant find anything wrong with throtle body

to effect TPS in bad way

code 120 is the only code

any help

The code is for the sensor circuit, not the sensor. Check the wiring to the sensor for a faulty connection.

will do, i did mess with the harness a bit when swaping the trans

i hope its an easy find,

any ideas about the rest..........

Check the relay for the AC fan and see if the relay is bad or if something is turning the relay on.

i was thinking that too

update

the TPS problem was related to an loose engine harness main plug

i will check the fan relay monday

the "soft" shut off is still confusing me

does anybody think the ignition switch could coase a "soft" shut off???

Good to hear you are making progress. Try pulling the fuse for the ignition system to see how the engine shuts down then.

DId you replace the tranny or did a shop?

i am the shop

 

why???

why???

 

Was just wondering if the green diagnostic connector under the dash was hooked up, and then never disconnected. That is usually the reasons the fans are always on, along with other weirdness.

well i will look and see,

i bought this car from the junk yard

along with 5 other legacy's( i flip them)

and have done a tranny swap and rad support

front metal, and 60k service to motor

and some interior work, but i havent touched the connectors myself

but i will look and see

*whew*

 

i didnt want to cast doubt on your technical skill, at least now we can blame the junkyard

ok, so i looked at the connectors

( i am now in pain, dont ask)

they are not hooked up

darn it, i was hoping on that

Just for giggles, do you have another ECU you can swap in?

yes i do, will try in the morning

Weird fan action, without the green connnectors together, is one of the reasons to suspect the ECU.

so i swaped the ecu, no change, swaped all the a/c relays in the front fuse box, no change, when i pull the 10amp fuse in the underhood box the fan shuts off,

 

both ecus acted the exact same

 

everything on the car works fine, well a/c needs freon

but thats it

and frreon level should not turn on the fan

this one is stating to bug me

next idea.........

Check the relay for the AC fan and see if the relay is bad or if something is turning the relay on.

 

what could be turning the relay on

im confused on this

i have swaped all 4 little relays in the under hood fuse block

with no change, also pulling the 10amp a/c fuse stops the fan

a/c doesnt actually work---no freon

and the switch on the inside is off, and the defrost is not on

Something may be hooked up incorrectly. You could try disconnecting things to see if that will shut the fan down. There may be a problem within the AC controller that is causing this also.

what and where is the a/c controller??????

I think there is a module under the dash for the AC system. That is what I meant by controller.
