I have a 99 auto integra with a p1106 code. Barometric pressure
I replaced cat and ecu. Still throwing code. When I mash gas to the floor it bogs and accelerated really slowly and won't go last around 4k rpm unless I downshift to third. I dunno what else to check I'm very frustrated.

Check the MAP sensor. Most of the Honda ECUs have a barometric pressure sensor built into the ECU itself, and you've replaced the ECU so that is obviously not the problem. But, some engine management strategies compare the barometric pressure sensor reading with the MAP sensor reading before engine startup (the MAP sensor reads ambient pressure when the engine isn't running). So it's possible that you actually have a MAP sensor problem. I'm not sure if that's something that Honda does as part of their engine management strategy, but it's worth checking the MAP sensor to see what you find.

So it could be the map sensor? That's the one on top of the throttle body right?

Fabrik8

Yes, could be the MAP sensor. I can't remember where it is, but that sounds about right.

Ive got an extra ill switch it late tonight after work and see.

If it doesn't work, check the wiring also. It doesn't matter what condition the sensor is in if the wiring is broken or otherwise faulty.

Thanks! Will do and report back! I guess its possible but if its map sensor why no map sensor code?

dcninja757

I'll switch it probably Monday night and post back.

i switched it just now. drives the same.

cliff's notes... barometric pressure code p1106
replaced: ecu, MAP sensor, catalytic converter...

did not replace TPS, should I do that even tho it's not throwing a tps code? Also, i did replace the throttle body at one point so is it possible that the code or no passing gear kicking in when i mash the gas is because the auto tranny cable is out of adjustment? i mean everything else seems to shift fine so I don't get it. I'm really lost on this one... anymore help would really be appreciated, it's like my car has a ghost I can't see lol

Hmmm. I don't ever touch auto tranny cars, so you're on your own for the transmission problem. Did you replace the throttle body gasket when you replaced the throttle body? I'm trying to think if there is anything that would cause a strange baro code having to do with a manifold or throttle body leak. I've heard of some people getting baro codes when they have filter blockages and vac leaks, but I've never experienced that personally so I can't really say if that could cause the problem you're having.
