i have a 96 itr engine in a hatch 96. I didn't have the air intake temp sensor connected for about 4 months because when I got it swapped I didn't really check for anything. But now when i wired it up and reset the ecu the car starts fine with no codes, but when i rev it up a couple of mins later i throw the knock code. But if don't connect the air intake temp sensor the knock doesn't go off. Can anyone please help i just adjusted my valves and they needing adjusting but it's still knocking.

 

You sure you have the right plug plugged in to the IAT? There are about 2-3 plugs in that area that look the same. Better check that, you can fry a portion of your ECU if the wrong plug is plugged in. Trust me, I know from experience.

d0h!!

 

Isnt the IAT the same as the map and TPS?

 

I beleive the knock wire is the same too.

 

i think i connected everything right i went off a helms manuel and here is what i know. connector D; Knock sensor wire is red/blue so i know i didn't connect IAT sensor to that, the IAT wire color is red/yellow and the other ground SG2 wire color is green and black. both wires i got from the harness, i opened it up near where the battery goes and got the wires from there and ran the to the IAT sensor. I was talking to my friend and he said maybe i need better gas i'm running 91 always have, i'm going to try an octane booster this weekend. any ideas


here is a link to explain what i'm talking about.

bump

 

1) no bumping
2) This doesnt belong in this forum in the first place
3) What ECU are you running?
4) If it wasnt throwing a code in the first place, why mess with it?
5) I take it this is a JDM motor?

 

what forum does it go in yes it is a jdm motor I'm running the stock ecu for the motor. is was throwing a code. code 10 then i fixed that code and it starting code 23 knock. i would start it no codes step on the gas and go around block then the knock code goes off. so i check everything and my valves need adjusting so i adjusted them. reset ecu, same thing started the car no codes go around the block and knock code again. BUT if I unplug the IAT senor, i just throw that code BUT no knock. So i don't know whats going on. I mean Knock or IAT, it's one or the other but not both. any explanation for this. because i wanted to get some work done and buy some parts but i want the engine running good. I don't want to blow it up or hurt.
