i have seached but im unsure as how to adjust the tps sensor. this really sucks because when the engine light comes up i lose vtec. i need my vtec!

so if anyone has a how to adjust guide it would be most appriciated. what kind of tools do i need as well. im just lost when it comes to sensors. is the tps bypassable? just curious.

thanks much

 

You need a volt meter and a Helm manual would help.
Voltage should be at .5v at closed throttle and I think 5.v at full throttle. I'll check my helms though. When it's within spec tighten down with allen screws.

 

TPS? Did you get the memo?

 

It sounds wonderfully easy on paper, but in practice, using a voltmeter/multimeter - especially a cheapa$$ one like from the local Crappy Tire - is just not going to work. It's completely inaccurate over such a broad range.

I haven't really figured out how to adjust the TPS while taking into account the inaccurate voltmeters yet I'm trying to get mine adjusted right also (currently the voltmeter says 0.3V closed, 4V at WOT, adjust it higher and the engine races on idle and during deceleration).

I figure the best thing to do would be to use Hondata S200 with datalogging option or at least digital dash and adjust the TPS based on the volts the ECU is seeing. But that's impractical due to expenses

 

well it doesn't sound too easy, guess i'll go to he shop and try to adjust it today.

thanks for the help....

if anyone has a helms and they can look up the exact spec volts for the tps please post them.

THANKS!

 

Fully closed throttle, appx 0.5v (with vacuum applied to dashpot.)
fully open throttle 4.5v no vacuum applied.
there sholud be a smooth transition from from 0.5 to 4.5v as throttle is opened to wide open position.

That is correct... Hondata can tell you how to adjust the TPS correctly

I just can't do it right, that's all

 

I got mine on the first try I'm lucky. I used a craftsman DVOM.

well its going to the shop tomarrow for some brake work anyways so i'll have them look at it while im there. i could do it, but why not just have my gear heads do it while they have it ya know. thanks for all the input.

 

I hate it too! putting it at 0.5V and 0.45V as some people say didn't help my idle problems so now I have mine set at 0.32V which seems to be better.
