hellpp please, engine turns off by itself Options

[immortal]

hello boys
i have a 98 jmd celica ss3 and i have a big problem and i am wondering if you can help me
basically when my car reaches its normal temperature and i am stopped in traffic lights the rmp is going up and down and after few seconds my engine turns off itself
did anobody have the same problem before?

[celicaGT96]

Do you have a cel, if so it might be your throttle positioning sensor.
at least thats what I would look into

soo guys i reset my ECU and everything works fine now

[creis]

^ weird. and how do you reset an ECU?, is there a reset buttom.

mine does that a little when I first turn it, it kinda struggles for a sec, and sometimes just sits at low rpm (like 500 ish) but it runs just fine if I rev the pettle up even just slightly makes a diff. I think mine is that the throttle cable is to lose or something)

no unfortunately there is no reset button.
follow the link above chanh55 posted and i think you will see improvemenets of your celica
do anybody knows how many rpm the engine must work when it its idle?

hello guys
it seems that my problem didnt solved by reseting the ecu
i still have the problem unfortunately
did anybody knows more about coolant sensor?
a friend told me that the problem maybe is here

[azian_advanced]

yes, you may have a faulty coolant temp sensor. mine was faulty and i was getting a low idle.

what happens is since the coolant temperature sensor isn't reading the temperature (seeing that's it's faulty or broken) that the ECU uses a fail-safe temperature (probably around 40 oC) and assumes the coolant is at that temperature (which really is NOT). and because of that, you would get a low idle.

usually this is the case during a cold morning start-up but this shouldn't be the case if your engine is already warmed up.

i'm guessing your injectors may need cleaning.. because if that's the case, you'd get anywhere between a low idle to a normal idle.. and bounces up and down in that range. if that's the problem, just take your car to a mechanic and have the injectors cleaned, or buy a bottle of the injector cleaner which is only about $6

clean your AIC too. my car stalled when warm, replaced my aic and no more stalls. but your can clean it with degreaser or cleaner.

does ur car turn back on after it turns off??? or does it just crank but not fire?

bboy

hello and thanks for the reply
basically i have the problem when my car is hot after driving in town and when the traffic lights are red and i stop and leave the petrol pedal idle the rpm is going up and down and after 2-3 sec. it turns off.
i can turn it on with the switch but when i leave the petrol pedal idle again is turns off again:(
i try the stp injector cleaner but nothing happens.
a friend told me that the problem maybe the coolant sensor and if i disconnect it he told me that the car would be ok
is it true? do anybody knows where is the coolant senor?
please help me guys i have a big problem here

[immortal]

LewFX what is AIC? can you please tell me?

[immortal]

guys unfortunately i still have the problem:(
i took it on a garage and put the car in the dignostic tool and it shows that there is a problem with air intake circuit
do anybody knows how to fix it please?

[immortal]

nobody guys?

[Agent21]

You need to clean or replace the idle air control valve. It is on the bottom of the throttle body...atleast it is on the 5sfe not 100% sure about the beams 3sge. You can clean it with any intake cleaner or even carb cleaner if you are strapped......or you can just send the car to me and I'll give it s good home.

[immortal]

you mean the air intake sensor located next to the air filter?
thats the problem i get with diagnostic tool : ---> P0110 Intake Air Temperature Circuit.

[Agent21]

Oh that sensor. Yeah I'd just replace that or make sure it is in good and tight. Didn't think it would mess up the running of the engine though.

[immortal]

yes agent i think here is my problem..
i will try to find another sensor from a friend`s celica and put it on my car to see if the problem occur again..
but i think my sensor is bad and that makes the problem occurs
how much is a brand new sensor if you know?

[Agent21]

Dunno off the top of my head and since I live in the US I probably can't help even if I did, sorry. Atleast you got it diagnosed.

[immortal]

are you sure is the airflow sensor the problem?
