Been having a problem with my tps I connected the stock ecu and the car ran fine but put the emange harness ad I throw the tps code I checked everything an in the parameter It keeps saving .25v for the throttle anybody have any insight on this anything is helpful

 

Have you tried to recalibrate the TPS?

 

How do you do that?

 

First you'd find the volts that it's supposed to be set at for closed and WOT. Then you'd check the volts, off the sensor. If they're not what they're supposed to be, then loosen the bolts on the TPS and adjust it until it's right.

I put a bigger TB on my Prelude without calibrating the TPS. It ran fine, except for the drop in gas mileage. Once S300 was installed, I found out that my TPS was off by like 10%. You live and you learn.

 

Thanks I guess I'll try that

 

I tried it and nothing... I hit the throttle all the way when the car is off and I get 4.40v and when I let off I only get.25v same v when the car is on.. Switched 3 tps anybody got a clue cause I'm lost I even changed the tb

 

Sill having the problem can anybody help

 

Did you adjust the TPS or did you just throw a different one on? You should be able to loosen the bolts and twist it some.

 

im having a similar issue i went from going 30miles and throwing the cel to 70miles just from a adjustment on this screen emanage screen.if you do not have a a/f gauge i wouldnt suggest doing this. if your injector size is correct then you need to change the i/j lag time.if you go 0.0 it will run richer 0.5 will run lean so im trying .3 and it seems to be ok.let me know how it works out for you,i also thought it was my tps

 

any luck?
