Hey all. I swapped engines in my 2009 Subaru Impreza 2.5I with a JDM boxer engine. After the swap I went through some of the codes (there are a few) and one that stuck out is P1491 which is a PCV function problem. The JDM motor I threw in didn't even have the sensor itself that connects somewhere on the intake so the ECU will never get a signal from the boxer engine wiring harness. I've read online that the sensor is essentially useless as it only checks for voltage making sure the thing is plugged in. Can I just rig up a little jumper cable between the two pins on the cars ECU so it completes the useless circuit? If so, does anyone have the pinout for the 09 Impreza 2.5I? The car is also throwing some ABS codes (0316, C0057. C0072) but I wanna take this one step at a time. Thanks!
