    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!

    Hey all. Starting a new thread because it's been awhile since my last post about this topic. Long story short - I have a 2009 Subaru Impreza 2.5I that I did a JDM boxer engine (EJ253) swap with. Everything went smooth except I am getting a P1491 code (PCV sensor error). This is because the boxer engine I put in physically does not have the sensor itself and therefore the ECM from the car is not picking anything up on its end. So after some digging through the FSM I think I found the correct pins where I can put a resistor or jumper on the ECM to artificially complete the circuit and bypass the code. The only problem is that those pins are currently occupied and I am nervous that they may be running to something else. Could JDM just have capped the ends of these two wires somewhere in the harness or are they actually being used? Does anyone have any experience with this? I'm attaching some photos for reference. Picture 1: Wiring diagram found in the FSM. My plan is to put a resistor between pin 41 and pin 45 on B21 (wiring harness from the boxer engine) Picture 2: The back of the wiring harness from the boxer engine. Note that pin 41 is occupied by a yellow / red wire while pin 45 (hard to see) is occupied by a solid orange wire. Appreciate all the help and let me know if my logic is flawed! - Geoff
