i put a b18b swap in my 91 crx hf. im throwing a code 13. baro sensor. this is the first time ive ever got this code from a swap that ive done. does anybody know wtf that sensor looks like or where it might be located. o yeah im running a pr4 ecu.

 

same boat looking for an answer on how to fix this too.

 

bump

 

ok maybe a little more info. its a obd1 motor wired with my hf harness. there is a black sensor on the top right of the intake manifold. my harness did not have a plug that i could plug into it. i left my factory map and the other sensors on the firewall plugged up. today i went ahead and extended the map wires so they would reach the one on the throttle body. is one of the other sensors on the firewall like the one one the maniflod? also i cant get it in time. i have to advance the dizzy all the way just to get it close to the correct timing mark. if i put it in the middle(on the dizzy) it is almost at tdc. took the valve cover off to check the timing and it seemed to be correct. could my ecu or the code 13 be effecting that?
