Customer Question

Customer: hello, I have a 2000 maxima 2000. I have replaced the iac and the ecm but am unable to make the relearn procedure work. Is there a way to test the new iac? I have worked through the nissan fsm flow chart and still no luck
JA: Thanks. Can you give me any more details about your issue?
Customer: yes, p0505 code was set with bad idle. checked the ecm and it was burned. ordered ecm from ebay and new aftermarket iac. My neighbor is a nissan mechanic, he took it to the shop for free to use the consult but it would not relearn the idle. I have worked through the fsm and still no luck
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $20) to post your type of question to Nissan Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: I have worked two days, 20.00 would be very good if you have the magic answers
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

just checking, are you still there?

All IA Volume Learning conditions were met. Procedure was tried at least 5 times. Step 9 on page EC513 indicates a buzzing should be heard at the iac solenoid valve when the key is switched on, I do not hear this. Procedure indicates if no good, go to step 10, either replace iac or perform IA Volume Learning. I did purchase another new iac from Advance Auto but no sound from it either.

After each Re-Learning, idle remains at 1100 +/-.
