baro pressure sensor keeps going off i've tried 3 different ecu's and it keeps going off in my 91 integra which is completely stock

 

try a new throttle body/map sensor. and you will be good.

 

Thanks man I"ll give it a shot

 

Nah the barometrics pressure sensor isn't in the throttle body. It depends on which ecu you are using. OBD1 cars had the sensor INSIDE the ecu. Older cars had an external sensor under the dash. I'd check the service manual for your car to verify the location of the sensor.

All the sensor is is a map sensor that reads open atmosphere all the time (to get the TRUE map reading by comparing it to manifold vacuum).
