Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your Question.
No you can't just plug it in. With this P0505 code you will need to replace the Ecm and Idle Air Control Valve both at the same time.
Once the Ecm is installed, then the keys will need to be programmed so the car can be started. Once started then it will need to go to the dealer for a Idle Relearn to verify the repair.
A mobile locksmith can come program the keys for you after you replace both parts. Make sure they are both done at the same time, other wise you will never get ahead of resolving the issue.
If you have any more questions on this, please feel free to ask.
