So, i had another CEL pop on last week sometime(willing to bet its the insane wireing job on the swap).... i checked the code on the ECU and it flashes 1 long, 1 med, and 3 short (23? 13?)

Code 13 being Atmospheric pressure sensor...
Code 23 being Knock sensor

ive reset the ecu twice, and it still comes right back on.... the light doesnt come on until the car is warmed up...

also on a side note, ive looked at about 4 diff CEL trouble code lists and non show a code 23.... but all have the 13

Someone wanna point me in the right direction?

its a b16a sir swapped into an 88 crx w/ the pr3 ecu
 
did both lights go away? the atmospheric pressure sensor(barometer) is actually built into the ecu-on obd-0's(dont know about obd 1-2.)

yea, all is well... the PA sensor is actually on the pass side kick panel in the crx's.... it wasnt a PA code after all, just a knock sensor (in which the connector was just unplugged)
 
88-91 CRX have external PA sensor
88-90 Integras have external PA sensor
89-91 DA8 / EF8 B16A1 PW0/PR3 have external PA sensor

91 OBD0 Integra PR4 have internal PA sensor
92-95 USDM OBD1 Civic/integra ECU have internal PA sensor
90-93 USD Accord have internal PA sensor

JDM ECUs lack PA sensor.
