So I've finally got my h22 swap into my teg start! Hooked everything up for the engine to run and now checkin cel's. I get code 3 which is the MAP sensor, I checked to make sure everything's good and it seams fine, I'm using the map sensor from my old engine b18b1, hope that doesn't cause a problem. So I tried a few things, the wiring harness I have is from hasport and some of the colors from the wires are differen't so I can't really check them in a wiring manual, so I switched the TPS and MAP sensor connectors to see if that would change anything. I started it up and I got code 7 TPS sensor but the map sensor code went away. Then I hooked it back to how it originaly was and started the car and the code 7 TPS sensor went away but the code 3 MAP sensor came back again. Any help would be greatly appreciated!

 

could have gotten dirty when switching over.. or maybe its just gone bad at an inopportune time. map sensors are around 160 dollars... so maybe you could get a friend to lend you his, hook it up, clear the codes and see if it comes back, ive had this happen b4, bought a new one and the code was gone...
