I’ve come to understand that the atmospheric pressure sensor (code 13) is inside the ECU in my 1991 GS. However my mechanic isnt so sure so I told him I’ll find the picture of the inside compairision of the two ECU’s showing the Baro sensor inside the ECU and not outside the ECU as his LS paperwork on honda acura repair is showing him.

At one time someone threw me a link to a picture of the innerds of the 1991 GS ECU and I was hoping someone else could please be so kind as to provide this info 4 me.
Thanks

it is inside on the 91 ecu but out side on the 90 ecu if you look above the passanger kick panel you will see it are you sure your is a 91 an not a 90 might be an early switch over

so my 1991 gs has the barometric pressure sensor on the outside of the ecu ?? If it is it isnt where it should be.
Man I need to searchg for a 1991 GS ECU for sale. Either online here or from any vendors . Know of any ?
