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 drving my 95 Civic LX until I get this problem fixed and ref'd so I can drop in the B20 and VTEC it.
Thanks
