tps problem

jamesls · #1 (**permalink**) 01-10-2008, 08:22 AM

2001 prelude is throwing a tps code on the computer. Its turning over but its not getting any spark when its cold outside so i took it to honda and of course they say its the tps cause thats what the computer says. Who gives a **** where the throttles at when you turn the key over no spark = no spark. Has anyon e had this prob before oh and of course the tps is rivited on the throttle body and a new one from honds $700 ha ha ha. Can you put a throttle body from a 97 on a 01 are they capatable??

They are actually not rivets, they are bolts with the heads cut off/flattened. You will have to drill out or grind off the tops to get the tps off then take vice grips and unscrew the rest of the bolt. You have to be careful, if the bolts break when you are trying to turn them out you will have to drill them out the rest of the way then make new threads with a kit from the auto store. Or you can use a tap and die set like I did. You also have to calibrate it. I didnt calibrate mine though; I just turned it until the car shifted smoothly. You have to look in the 5th gen service manual to find out how to calibrate it. I get much better gas mileage with the new tps as well. Dont forget the throttle body gasket. You can find screws that will fit at the hardware store, they are size M5x0.8

edit-I also dont think the tps is the reason why your car doesnt start. Mine ran fine without my tps even connected.

edit #2- that second link is also very helpful

how do you calibrate it because i got a tps from a 91 prelude. then i put it on and restarted the ecu but it was still throwing the code?
i got a 4g. and also how do i get rid of code 36??

fix what you know is wrong first.

You need a multimeter to make sure the voltage is correct at closed and WOT. You can also test continuity to make sure there are no shorts in the harness.

take the red lead and backprobe the connector into the middle pin with it connected to the throttle. Touch the black lead to a body ground and test the voltage at fully closed and fully open. you should get ~.5 volts at closed and and ~4.5v at WOT. You can buy used throttle bodies much cheaper than replacing the sensor. www.omniman.com sells TPS sensors separately.

^ what he said

yea if you can find a throttle body on ebay with a tps go for that, its a PITA to change the tps

there is no code 36...maybe you have 3 and 6? your talking about the orange cel right?

its not really hard for me to take of the tps(my friend did the hard part) well i just wanna know if my tps work and ima try to get a multimeter to cheak it out my car idles when i started and stays at 800rpm then when its hot it gose up to 1000-1200rpm so I'm thinking is the fitv rite?
and i have a jdm ecu and code 36 traction control I just don't know hot to get rid of it.

hojemwod i agree sure my cars throwing a tps code and you clear it out it comes back. Who cares i think its the distibuter i fought one for $100 at a junkyard ill try it tommorow. The mechanic at honda says that the tps sends info to the computer to send spark im not buying that.

mizlude · #9 (**permalink**) 01-10-2008, 07:28 PM

Oh and here is a cheep brand new tps if you end up needing one bro.

it definitely doesnt send spark info...at least not on mine lol...the cars have a backup system for when something like the tps is disconnected, then engine will run, and shift at preset speeds etc. at least the 4th gens do and i dont see why the 5th wouldnt.

$100 for a distributor?....do you mean $10...my jy sells em for $10...i hope you dont mean 100

its in Pa, there are definitely no 5th gens in there though, if there were the distributor would still be $10

damn i got jacked for a $100 today and put the distibuter on and still no spark. Ill probually never fix the prob.

hojemwod · #14 (**permalink**) 01-11-2008, 07:08 PM

see if it starts with your tps disconnected..because then it would go to the backup settings..also maybe your not getting any gas..maybe your spark plugs are bad, maybe you got another bad distributor?

jamesls · #15 (**permalink**) 01-12-2008, 07:06 PM

its gettin plenty gas you can smell it. It has new plugs. Im sure the distibuters good. Ill try and unplug the tps the next 70 degree day we have its probually gonna be in about a week.
