Asked by AJADEN Oct 02, 2015 at 12:05 AM about the 2004 Subaru Legacy

Question type: Maintenance & Repair

The 2005 Legacy 2.5 L was an electronic carburetor while the 2004 Subaru Legacy is manually activated. The engine was installed and all the necessary wiring was swapped but the car would not start despite that I drove the 2005 Subaru Legacy that the new engine came off. Rather, my mechanic friend received a P0336 error code (cam shaft sensor code). He suggested we should take it to the dealership as it seems like a timing problem. Please could someone help with any input. Thanks.

A 2004 Subaru Legacy does not have a carburetor. It has MPFI Multi-Port Fuel injection and a throttle body. I think you are referring to drive-by-wire with a servo motor on the throttle body vs. a cable. The ignition timing is controlled by the ECU and not adjustable. To shorten the story yes just take to dealer

Yes, you were right. I am a novice when it comes to cars and that was the best way I could describe it. Also, could it be we have to replace the ECU with the one the new engine came off? Thanks for the input.

Sorry, didn't mean to sound like a 3rd grade teacher lecturing you. It's all good. But actually the ECU from the old engine might still recognize your keys... or will have to be programmed to recognize your keys
