^ I've been fiddling with my TPS lately, thinking it could be the reason for my running issue. When I was playing with the adjustments, if you go too far (example: 4.5v at closed throttle) the idle will drop out after revving and even stall. so If you've just replaced your TPS perhaps the idle voltage is set too high/low.
I'm going to try cleaning the throttle body/MAP as well as continue fooling with TPS settings.
Right now I believe it's at 2.7v at "idle" (closed throttle) and it's idling/dropping back to idle fine.
I'm getting this bucking on take-off in 1st at about 1500rpm and even sometimes at around 2000-3000rpm when I let off the gas ever so slightly.
It's not a miss but it feels like a random fuel cut-off or something. Seems to be related to how much the accelerator is depressed.
Totally annoying and fairly embarrassing when driving this type of car haha
You will not get a CEL if your TPS has a glitch in it, because it doesn't happen all the time so the ECM won't trigger the code. You will only get a TPS code for high/low input circuit.
If you suspect your TPS has a glitch, stumbles on acceleration and then returns to normal, then you would need a lab scope and do a snap test to see the voltage drop (the glitch). Or you may try using a DMM, and what the voltage rise and if you see a drop in voltage while opening the throttle, then the TPS is no good. But that method is very hard to catch the glitch, lab scope works best, but it's an expensive tool.
All I've done so far is plug in the Solus and check the voltage at Closed Throttle and at WOT. Haven't spent too much time on it but it's becoming more annoying so I want to get it taken care of.
We have the Verus as well so I can try out your scope test. It only does it under load so I'll have to take it for a drive while recording or have a buddy watching.
I'm also going to pop out the MAP and see if cleaning it and the throttle body helps at all. As the rest of the maintenance on this vehicle was lacking, I'm sure cleaning anything wasn't a priority.
bringing back the old thread better than starting a new one.
I have an 06 DBW and currently having the hesitation problem so I'm suspecting the TPS since I already replaced the APP sensor. The TPS on my 06 does not look the same as the pictures provided on the first page. will the Omni or the civic/integra TPS work with an 06+? if not then will I have to replace the throttle body?
So I was having the jerky hesitation problems that many have reported, but the car would never throw a DTC. Mine would occasionally stumble only when cold and only between 2500-3000 rpms. After it warmed up it was fine. I checked TPS V at idle and WOT, MAP, PHOS, every piece of the secondary air injection, plugs, coils, fuel - all checked fine. Finally I checked the TPS again, but this time I slowly rotated the sensor and monitored the voltage - found a ratty section that was very unstable. So now I start looking for a new TPS, but you have to buy the whole throttle body . The local dealer wanted $550, and majestic (online) gets $476. That's alot of coin for a 0-5V potentiometer. So instead I bought an OmniPower TPS for $75, and buzzed off the flanges so that I could rotate it to .30V at idle. Works great and voltage at WOT is correct also.
UPDATE: Omni Power now has a TPS that fits the S2000 directly - no need to cut off the plastic flanges now.
Do they ? Can't find F20/F22 TPS at http://omnipowerusa.com/tps_sensors.asp What Which one did you use ? I have big problems due to interferances at idle, it's jumping about 1-3%
