hi everybody

my service engine soon light came on and code reader is saying it's TPS,so i'd like to know where is it exactly located...is it on the tb or somewhere else...
i took of my tb and cleaned it with tb cleaner as i was advised but nothing happened... so if anyone knows anything about this or how to fix it please let me know...right now when i step on my gas pedal nothing's going on
it's 2004 g35 coupe


thanx

 

Are you sure that isn't the Tire Pressure Sensor? I'm not sure if 04's have them or not.

 

I'm having a similar problem.

car starts and idles at around 1000rpm

no throttle response

error codes show bad throttle pedal sensor... tried a new one... same problem..

tried a new throttle body... same problem...

Did anyone ever figure this out?

 

is your car running now?
mine is not,it starts and idles but it doesn't go...when i turn it on i can rev it up 2-3 times and then it looses throttle response...the other day i've cleaned my tb and took it out for a spin and it worked just fine, yesterday same problem again...i don't know what's going on

 

it's throttle position sensor,i just found out it's located on tb...i've got low k's on mine just over 60k's this shouldn't go that soon

 

i dont have any throttle response at all... its like the pedal is disconnected

 

did you disconnect the TB harness when you cleaned the TB? how did you clean the TB?

 

just took off four bolts,without disconnecting tb pulled it to the side and cleaned both sides...with my car off of course...
but i had problem with it couple years ago,left the car in my garage over winter
and in spring time it was just fine i didn't do anything to it...got fixed by it self i guess...

 

could it be that you shifted the buttlerfly valve too much when cleaning the TB and now your ECU is way out of wack and wont respond properly?

 

if you have a friend with the same car, try taking his throttle "known good sensor, stick it in your car and see if your car runs normal, if it does run normal then i would say u need a new tps. imo.

 

^ that wouldnt do anything. the ECU has been programed to the last proper position of his TB. If he sticks someone else's Tb on his car it'll still misread the position

 

if its NOT the pedal or throttle body what could it be?
