very odd, first is started off with a TPS code, which i replaced, than with some help of honda tech users INCLUDING "klungemonger" who helped me out a lot! i tricked the stock 99-00 Si ecu into thinking i have the crank sensor and the vtec presure sensor, which i got rid of those 2 codes, and of course i fixed the TPS, i ordered a brand new one from street imports

now when i drive it sometimes this baro CEL comes up and i gota diss. the battery or wipe the code to get rid of it, this is happening on Si ecu, and last nite it CEL was coming on on the jdm ecu aswell but im not 100% if its the same code, never troubleshooted it with the jdm ecu but im sure it is... anyone have any idea what this is? this started happening since i installed the new TPS

is the tps installed correctly? have you tried to open the tps to see if the valve is adjust rright? how is your idle?

alien

i must say the TPS is not yet calibrated, i thought that would be the problem?

happen to my car. i installed a tps off of my friends civic but it was still throwing the code. after i readjusted it the code went away. when you let your car idle how high are the rpms?

the BARO code is for the atmospheric pressure sensor and its inside the ecu. there is no diagnostic procedure for this code other than to replace the ecu. this info from mitchell on demand so your looking at an ecu problem

its funy, when i crack vtec and lay off, rpms will stay at 2k untill i come to a complete spot. but after high rpm it does sometimes idle really rough, low like .2 or so

.. i know its not ecu, i just passed deq with a working Si ecu, and the jdm that came with the hmotor motor? that no good too?

it be crazy if both are burned

So what is the code off the jdm ECU. the idle problem you describe isa little vague and could be any number of sensors. im not sure of what kind of diagnostic tools you own or have access to but a digital oscilliscope would be the most precise and error proof way to start testing things. but for starters TPS should be taken care of first.
