I have code 13 (atomosphere pressure sensor) and 3 (map sensor) on my ecu. I know where the map sensor is but the manual show's nothing on the atmosphere pressure sensor. Does anyone know where it is?

 

i belive the pressure sensor is built into the map sensor

 

I think you might be right. There's 2 connectors on the map sensor. Any one else have any info?

 

I think the PA (Atmospheric Pressure) sensor is located inside the car, passenger side, near the side vents. You know how the Main Relay is located on the driver side, the PA sensor is located at the same place, but on the passenger side.

 

In the 4th gen, it's located on the passenger side right side panel, just above the plastic. The diagnostic connector is there, too. On later gens, the PA sensor is inside the ECU.

 

yeah i read somewhere that its right by that little plug on the passsenger side behind the plastic stuff.

 

:shrugs:

 

I have a '89 Civic, is it going to be inside the ecu?
