i have a 90 computer in my 91 integra. In a previous post i made, i stated that the check engine light is on because of ecu code 13: atmospheric pressure sensor.

Another member replied and told me that the 90 PA is external, and the 91 is internal

I just need to know if it is safe to drive around without harming anything! Please help!

 

no one knows?

 

You should be fine the sensor mesures the outside air to give a correct air fuel mixture. Higher altitude less air lower more air. The car will just go into a fail safe mode and you should be able to drive it. Worse possibility is you will be running rich and get bad gas milage other then that your fine.

 

thanks
