Correct voltage settings for the TPS ?
on: 12 June, 2019, 01:04:30 PM
Can anyone help? Diagnostic highlighted incorrect settings/voltage ie dodgy tps. Without going into replacing the entire throttle body, I bought a replacement TPS from China. As far as I know itís the same model/serial all correct. Put on bike and calibrated etc and the bike ran ok for almost 100 miles then the surge/lumpy jerky throttle and stalling on idle started. Can anyone give me the correct voltage settings for the TPS so I can check or and any advice pls. Honda dealer is no help and garages donít want to get involved. Iím not sure what this could be? The bike is charging correctly. Also, if anyone knows a good independent garage/mechanic that could help diagnose this. Thanks

Thanks so much mate. That is slightly different so I shall try that and cross my fingers. Hopefully the issue is just a case of tweaking.

you can go almost up t o 4,49 i usually set to 4,3 to 4,4 and then reset ecu. if over 4,5 you get a check light

remove battery terminal (either)

let for 5 mins to forget its troubles

connect battery terminal

start bike and let idle for over 3 minutes without touching throttle. it now learns how to idle correct.
(idea is to let it reach 102c and fan to kick in but it works also like this)


also tps reset is done with switch on and slowly turn accelerator to max and slowly release close ignition switch and test.

Hi mate. Your a legend! Btw what reading  are you getting on closed throttle?

Really appreciate your time mate.

Thanks again

the voltage readings for my original tps were
closed throttle 0.49v.full throttle 4.46v
 checked before i removed itso that i had a basic setting.

I normally set it at 0.5v closed throttle
using the 2volt scale on the meter

The TPS is a potentiometer of approx 1,5kOhm.
Applied voltage is approx 5VDC.
Output should be, according workshop manual:
0.4 Ė 0.6 V (throttle fully closed)
4.2 Ė 4.8 V (throttle fully opened)

You might also check the TPS by (ignition off) disconnecting the TPS and just measuring the resistance with a multimeter.

Well, anyway, either checking voltage or resistance, it is also important to check the value goes up corrosponding the gas throttle position.
in case you see the value make sudden jumps  :005: when slowly turning the gas throttle, the sensor is bad and needs replacement. :003:

Have fun,

You're replying to a year and a half old post   :087: 
I think it is sorted (and referenced elsewhere) by now.
Only do it right - no bodging please.   Keeper of the failed stator list.   John.
