When I was using hondata everything was fine and dandy. But it X'd itself and isn't working right now. Currently working on getting it sent to hondata to see if it can be fixed.

Closed V- .47v
WOT V- 4.75v

Source going into the sensor is at 5.04 but its the same for my MAP so maybe my meter is a little off.

When I clear my ecu and start it no cel. But the second I go to rev it it throws a CEL and will not rev over 2000 when I hit the gas. It just sounds like its hitting a rev limiter. Go WOT and it does the same but doesn't rev, just bogs down, slight backfire. AFR's go to 17.5 till I let it go back to idle. Throwing code 7 for TPS. I checked the voltage and pressed gas pedal slowly and the voltage is smooth and consistant.

Is it possible the sensor is bad even though its not reading crazy? thanks in advance.


edit: Car is on crome now. TPS calibration within the program has been set to what the sensor is giving me at the ecu. The car at one point did bog out till I got far enough into the throttle that it was smooth and normal and I was able to drive it, but it was like 30% or more. Anything lower was like an on/off switch with it bogging and then going.

 

where did you do the voltage check? at the sensor or the ECU? or are you using Hondata to read the voltage?

double check and clean thermostat grounds?

 

How dose the data read in the ecu? If its not 100% open in the data you could have some resistance in the signal wire leading back to the ecu

 

Checked at ecu. same at the sensor., going to try an OEM tps later today. Gonna run through grounds again as well.

 

Tried a different sensor, same result. Thought maybe it was wiring. So I wired straight to ecu and still the same issue. I'm starting to think its crome since when I was able to sync up the tps with sManager it was all gravy.

 

Since Crome is the only variable really before and after, it's pretty safe to assume it's something with the program. Have you fiddled with the duty cycle or anything else just to see what happens?

 

I have no idea if this is even relevant, but you didn't post which motor you're running ...

Im a crome user by chance are you running no iac? I have had problems with running no iac and bogging at lower rpms with crome.

 

I can't mess with that. i don't have a burner so I can't do that.
sorry its an h22(h2b)
no iacv. It bogs but it never clears up. Unless it'll clear up when the car reaches operating temps? The IAC was disable in crome. thoughts?


I edited my original post the other day to show that it did work at some point. I also read that crome doesn't datalog tps voltage. But the only time the car ran fine. It was logging my TPS on my tunerview which is weird. When it doesn't work, it just shows 15% all the time. I may tow it up to tuner and see if I can just start out clean with a new map and what not. I'd just hate to do that and have it not be it.

 

Set closed to .45v and open to 4.5v

 

With new sensor. It is .45 and 4.46. I'm not sure how I'm gonna get another .05 out of it. It's cranked all the way to one side.

 

Be sure you hold your mouth right.

 

Lol, I'll adjust it again to see what I can do.

 

Crome plus no iac for me anyway always = fail. It always bogs till about 1500-2000 rpms. Crome has tps voltage and % in pro anyway. Just take it to your tuner.

 

My bogs to 2000 and doesn't want to go over that if I hold my foot on the pedal. I seen others unplugging the tps and having their car run as far as being able to rev without bogging/bucking. Mine just does the same thing. I know it's gotta be a crome issue. If anything, I know he'll have an s300 I can try out there as well. Although I've never tried to let it sit idle till it warmed up to see if the problem cleared. Whatever it is, Regardless of which sensor i'm using, voltage going in and signal is consistent and not jumpy nor does it have dead spots. It actually didn't start throwing 7 till I disabled IACV. So maybe I'll turn it back on and see if the problem persists. I'll have to set something up with my tuner next weekend when I can tow it over to him.

 

Sounds like something in Crome, TBH... I would try a fresh chip to start with and if it doesnt fix it, try making a new tune and copying the maps and settings over from the previous tune.

 

That's what I'm gonna end up doing. I tried going back to a fresh map since the last time it actually went was when I had iacv enabled. So I went and did that and i'm still having the same issue. Voltage is on the nuts at the sensor and at the ecu as well as being calibrated. My tuner had an s300 unit chillin in his office so I took that and threw it in the car to see what would happen. Plugged it in, loaded a map. Started with ease and the "tps" issue was now non existant. Just a little rough in the mid range as the car hasn't been tuned on the new setup. But i'm able to rev it up, no CEL's.

I'm gonna talk to him tomorrow to see what he thinks about me towing it up there next sat and throwing it on the dyno and start fresh with a brand new map. Since the tune that's on there is from a friends h2b setup, but close to being identical. It drove me crazy. If it doesn't work, I'm gonna just buy an s300 unit and move on.

I know it seems strange that it works, why don't I just do it? race season is coming up quickly and I still need drag wheels/skinnies. At this point if I could squeeze in an s300 last. That's what i'd prefer to do. But sometimes **** doesn't go as planned and might have to do it the other way. Been itching to drive this thing over the last month or so, driving me crazy as i've been dicking with this issue for the last few weeks without success.
