I have a 91 Integra and the idle keeps going up and down. The ECU is showing an error code 13 (1 long and 3 short). All the charts I've seen say thats a BARO sensor. Does anyone know what or where this is? Any help would be greatly appreciated.

 

Where you modifying your car in any way, or did it just come on?
Did you try and reset the ECU?

 

i looked in my haynes manual and it said to have it checked out at the local dealer repair service shop??? so i dont know if that helped you or not but i tried???!!!

 

It's a stripped out race car, but I raced it for a couple of years before it started doing this.

 

:rofl: That's the advice you get when you purchase a Haynes manual. I just brought a Helms yesterday.

 

Try resetting the ECU first, it might have just gotten a random wierd signal from the sensor. If it comes on again and does the same thing, replace the sensor.

Oh, and get a Helms.

 

does anyone know where the BARO sensor is...i have heard that it is behind the dash, but that could be a lot to look through. 91' integra...just turbo'd trying to figure out why i'm getting code 13. Is it actually whats wrong, or is it something like the MAP sensor?

 

The baro sensor is in the ECU/ECM, and the book says to replace with a known good ecu. If the problem persists I don't knwo what to tell you as I have been dealing with the same problem for 3 months now. Anyone have an ECM that they want to trade for any other ecu's I have lying around???
