Ecu Code 13 Fix?

I have an 89 Civic LX 4DR with a 92 LS B18A1 with 92 GSR YS1. I am running a 90 PR4 ECU with a 90 Integra GS Underdash and engine harness. I am throwing a code 13 on the ECU which is the baro sensor. I have swapped out the ECU from a friends 91 and same code 13. The baro sensor is built into the ECU. the Helm says to troubleshoot the auto control box but the harness and ECU are 5-speed. Any help is appreciated as I am stuck driving my 95 Civic LX until I get this problem fixed and ref'd so I can drop in the B20 and VTEC it.

why don't you stop crapping on other ppl's thread's crx-1.8?

LXVTEC: open your PR4 ECU. Honda made two different revisions of PR4s - one has a PA sensor mounted internally, one does not. the PA sensor is a box about 1.5" x 1" x 0.25" that will be very clsoe to the mddle of the ECU if it is present at all.

There are ways to force a PR4 to run off an internal or external PA... after you figure out whether you have an internal or external one, we'll take it from there.

He's right. While he may have been a dick about it, don't threadjack other peoples' threads. Just start a new one. It isn't that tough.
