Calibrate Tps

[Flash89]

hey guys and gals, a quick one

how is the tps calibrated on a rb20?

[Flash89]

its been a while does anyone know??

I don't think there is any calibration as such? The sensor senses how far open it is and feeds the signal to the ECU as far as I know.

Adjusting your cable is another story. Take out the slack, and you could use a consult cable and software to confirm WOT. (with the car ignition on, but not running)

what i mean about calibration is so the tps is sending the right signals to the ecu cause at the moment i think the tps is out of its right position, meaning that is prob sending a signal that the throttle is like 5% open when its actually closed.

i just want to know how to set the tps back to the right position so its like 0% thorttle and the ecu is actually reading 0% thorttle

get me?

CONSULT should be able to display TPS position %

[Flash89]

there has to be another way, like using a voltimeter using the resistants on it etc etc

It can be done that way, you will need to find out the correct voltage for it (EG: the 300zx tps is set to 0.45v at 0%) the easiest way to do it is to find the correct voltage for closed throttle and then get a multi metre in there and set it to it. If you have someone with either a consult cable or an ecutalk lcd display this can be done easily (5 mins)

yeah you can just use a multimeter to check the voltage. the voltage should be around 0.45v when closed. this is pretty standard for a lot of nissans. pretty sure the sr20 is also the same. there will always be a slight variance though. i'm not sure exactly what the allowable margin is, but if yours is dramatically different then i'd have a play around with it. if i get time i'll have a look through some stuff i have and see if it says.

Sorry for dig up this topic, hopefully i'm in the right place to post my problem. Currently my car(bnr34) MFD show the throttle reading at 1-2% when idle, for what I know it should be 0% when idle, I pop-up my bonnet and check the stop-screw, it is backed off without touching the throttle linkage(1mm gap), but why the reading show 1-2% when idle? Will TPS cause the MFD throttle reading like this?

you can turn the sensor on the throttle which will adjust the voltage the tps is sending to the ecu.

Okie~ thanks bro~ ^^

your MFD is probably guessing what '0%' means. e.g. if it has decided 0.44v is 0%, then if its reading 0.46v then it will show as 1-2%. maybe there is a setting in the MFD to calibrate the 0/100% throttle voltages?
