inlet air temperature sensor were is it????

[noney82]

hi iv a j reg 325i e30 can anyone tell me if it has an inlet air temperature sensor? if so where is it. if possible can some one send me pics of it and where it is thank you, the email addy is nonny82@hotmail.com

also my Upload Avatar from your machine is disabled can you help with that one to pls as i want to add a pic of my beema to my avatar thingy like most people have at the end of their replys

fairly sure there is no such a thing as intake air temp sensor. you have an air mass meter which measures and regulates the amount of air going into the throttle body and the computer adjusts fuel to suit. you have an engine temp sensor which basically measures water temp and adjusts the fuel / air mixture accordingly. this is situated near the front of the fuel rail and is blue (the brown one in same location is for your temp guage)

IAT is built into the AFM before the flap dude

hmmm never knew that!! does it alter the feul/air ration much? what happens if they dont work?

[Project_E30]

They don't tend to fail really. I know people try to play with these to fool the ECU into thinking its freezing cold outside meaning it pumps in more fuel.

[mrLEE30]

but i thought the ECU got its temp readings for fueling from the Blue temp sensor alone, you can fool the engine in the same way by using a resistor instead of blue temp sensor, but why you would want to is beyond me unless you had a extreamly large TB on there otherwise would run too rich????

i am not being funny if anyone thinks so just quite interested in how it works, knowledge is power and all that!!

thats why im after the ATS to use on of them resistor things iv been told they increase power and other things to has anyone heard of this before or shed some light on this please thank you all for your replys

I'd seriously steer clear of things like that...I think this this thread from the other week is probably talking about something along the same lines:

Hopefully this should give you the advice you need!

i think i will follow your advise and bin it thank you all for your help on this, how do get pics at the end of my replys like when people put there beemas on
