P1065 Nissan Code - ECM Power Supply Circuit
Quick Answer
Battery voltage is supplied to the Engine Control Module (ECM) even when the ignition switch is turned OFF for the ECM memory function of the Diagnostic Trouble Code (DTC) memory, the air-fuel ratio feedback compensation value memory, the idle air volume learning value memory, etc. Common causes include Faulty Engine Control Module (ECM), Engine Control Module harness power supply circuit is open or shorted, Engine Control Module harness ground supply circuit is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

05 maxima 3.5 started running rough and white smoke that smelled of fuel coming from exhaust, replaced injector that was just pouring gas into cylinder, restarted, smoke stopped after a few minutes but car still wouldn't idle well and got service engine soon light code P1065 why?
-
There must be something else causing the problem (e.g. Air Flow Meter), when there is a problem with the ECM and the P1065 code is set, there are no engine performance problem.
-
My 04 Maxima 6spd lost all throttle couple of months ago and I've done pretty much everything in my knowledge but it seems like this will have to be sent to someone with knowledge. Won't rev pass 1400rpm and I have about 6 codes. P1126, P1122 "throttle body relay", P0300 "random/multiple misfire" and new added P1065. Any help will be appreciated.
-
Have you checked all the fuses? if all the fuses are OK then the most likely problem is the throttle body. Problems with the ECM (P1065) or a cylinder misfire code (P0300) wont cause the lost of throttle response.
-
I've replaced the entire IPDM, swapped the throttle body with the OEM one "I'm using an 09 MAXIMA tb" still limp mode.
-
I doubt using a TB from a 09 Maxima is a good test. If all the fuses are OK, then my best guess is that the problem is the TB, and after the TB has been replaced, the idle learn value needs to be reset.
-
The car worked for a while, raced and drove around like normal and suddenly the car just lost throttle. I took the throttle body and installed it in a friends car and it worked np. I wish it was the TB because it's the easiest thing to swap. I hope it's not the ECU or the ipdm because they're both expensive to replace.

Engine starts up and cuts off, but if you hold accelerator for start up then release it the engine will stay running with no problem.
