I have a 96 accord lx it was swapped with a f22b1/poh-l01 ecu. Vtec is wired in. The only code im throwing is p0141. Which is because the sensor is not there. The car revs in between 4500-5000rpms. It does not bounce off a limiter but just sounds like its wide open like if its all shes got. I just did the fast idle air valve which fixed my honda idle. And once i wired vtec in the car was more responsive. But i dont kno where else to go looking for problems. Timing belt water pump all gaskets and seals where just done. Any ideas ? Where to even start. Im thinking a clog mainly because the fast idle air controller was clogged to hell. And the lines too. Which i cleared.

Edit:
4500rpm rev in any gear.
6500rpm redline in neutral or clutch in. It even bounces off.

What happened to the second oxygen sensor ?

myaccord1993

It looks like it was never put on and the cat is further from the motor then normal i think anyways. Usually from what ive seen its manifold, downpipe. And the cat is just behind the front tires. On this one it closer to the front of the back wheels. Either way the sensor wire is near the front tires and my cat is towards the back. So they dont line up to even plug in.

holmesnmanny

Im guessing you think you have a cat but you dont. They may have put a test pipe on it.

myaccord1993

Ill take a picture and show you. It dosnt look like a test pipe but you may be right. Ill post a pic in the morning

Sounds like the object that you are referring to is the B pipe resonator. Somewhere over the years someone may have done a cat delete and replaced it with a straight pipe. AKA test pipe!

myaccord1993

You are 100% correct i looked today. There is no cat. But this does not resolve my issue. I just ran half a can of seafoam threw the vacume and half into the gas tank. 1/2 full. I just dont know what my problems is. Not enough fuel, not enough air... The car doesnt have a miss. I just dont understand.. I really wish i just had a list of things to start checking. Thats why I came on this forum. No better way to troubleshoot then to put 100s of brains together. Hopefully we are all just on the same page lol.

The secondary Os sensor is not a PGM-FI required sensor. It is more of an emissions sensor. It is only there to ensure that the catalyst system is working properly. Not to mention the P0141 is for the secondary heater circuit. It would definitely not put your ECU into limp mode.

One other thing I can think of would be to check your TPS and MAP sensor connections. They are both round 3 wire connectors and they can be mixed up.

TPS
GRN/BLU
RED/BLK
YEL/BLU

MAP
YEL/WHT
GRN/WHT
WHT/YEL

The sensors are both in the right position and functional. The car lately as of today at 5pm is reving and bouncing off at 6500 in nuetral or with clutch in. In gear im lucky to get to 5. Narrow anything down? The issue seems to be when the motor is underload. And when its at a high demand for fuel and air. Also i believe vtec kicks in between 25-3500 for the f22. Whcich i pinned into the ecu my self. Only reason i assume it is working is due to improvement in performance. And i have no cel for it. Also my car does not use the oil pressure switch for its vtec. I have the stock bolt in its place. I even thought maybe adjusting the throttle cable. But im feeling the car fall off. Not stay.. Am I correct by asumming its fine?

myaccord1993

Honestly i wanna try getting rid of p0141 and see if it fixes it. Its the only code and from what i understand there has to be a code if there is a limp. Everything seems to be in order except o2. And maybe timing adjustment. Ive been googling o2 simulaters. But i really need some recomendations before i start fiddiling with that.

holmesnmanny

Im not entirely if that code would cause your issues but i would severely doubt it. Try this, disconnect the primary oxygen sensor and see how it runs. Yes it will throw another code but it shouldnt go into immediate limp mode.

Im curious if the swap itself is done correctly, in terms of tdc/crank sensors etc etc. On obd1 cars it wont always throw a code but on obd2a i would imagine it would but not necessarily.

Check again that the crank sensors assmbly is hooked up properly.

myaccord1993

This car is obd11 what exactly am i looking for when i look at these sensors?

GhostAccord

I was just going to mention that is sounds more like an RPM related sensor is sending improper signals... then again the Accord redline is 6200RPM so you really aren't going to get it to do much over that.

myaccord1993

I will say speedometer and tach work. Odometer does not. If it plays any roll or shows a sign. Now again the car revs to 62 6500 w.e the exact redline is and bounces off all day mo problem. Aslong as the motor is not underload. (Driving) im gonna take a video and try to post it so you all can get a clear picture of what is going on. And im currently at work and it will be to dark for me to really check anything untill tomorrow. Also everyonce in awhile the idle will spike around. And lately it been 30 40 degreese out side and the car has been idling high even when the motor warms up. But i think that just needs timing done. And the thing that bothers me about it is all my gears are 2000 rpms shortter


Video of my problem. Anybody able to aprove the link for the video?

Your car is obd2 or it wouldnt be spitting out an obd2 code.

Look down at the crank and see if the crank sensor harness doesnt appear to be plugged in. It will have two connectors, one at the crank and another near the front balance shaft.

myaccord1993

Ill have to do it in the morning when i have sun. Where you able to watch the video?

Edit:

Ok so i really have no harnesses unplugged at all. Everything seems to be plugged in although i couldnt find exactly what you where talking about is it in cased in any thing? Here are some pictures.




The cable for the o2







Its a poj.

myaccord1993

Im still lost for things to look at could there be any other possible mix up of connectors

HonBeer

Someone did a hack and whack job on your car. Looks like there are unknown wires and non oem splices in the mix. Goodluck.

Cheers!

myaccord1993

Not really? Everything is in its place and plugged in
