Hey I got a 91 Integra with a 94 Integra LS motor wired for OBD0. I keep getting Code 13 - Barometric pressure sensor. Does anybody know what this is and how to diagnose it so that I can get rid of the check engine light.

 

if im not mistaken thats inside the ecu and you need to replace the ecu. of have it repaired. better off getting another ecu

 

Hey man you know what I forgot to mention that I actually did replace my original ecu and this new one is still kicking back Code 13. So I don't know man this is confusing the hell out of me.

 

try resetting your ecu if that doesnt help use a known good ecu and see if it goes away then you know your ecu is the problem

 

Cool I managed to get yet another ECu and sur enough the code 13 ceased to keep flashing. BUT, and there is always a but, code 43 is now showing regarding the fuel pressure system and a possible O2 sensor. Thats cool i can handle that with no problem i am sure. I'll let you guys know what happens. Thanks for the advice I appreciate it.

 

Hey, sorry to bring an old thread back, but what happened after this? I'm also having this problem.
