Discuss the causes and fixes for P1065 2005 Nissan Altima Sedan OBDII Code
-
"ecm power supply heater" No idea what that is.
The "ECM Power Supply", is the supply wire (circuit) that supplies power (voltage) to the Engine Control Module (ECM).
If the engine start and you have the code, then the problem is more than likely the ECM itself.
-
If my car reads code p1065 does it mean I have to replace computer on car ? Cars been sitting for roughly 7 months
-
Is the engine starting? any other symptoms? have you try clearing the code?
If the no other symptoms, but the code is clearing, then you do have to replace the Engine Control Module (ECM).
-
I have a 05 Nissan Altima 2.5 after replacing the head I started it and it ran about fast idle and then turned off, I got a code P1065. Maybe a ground issue or a open or shorted hardness? Maybe a MAP sensor?
-
You replaced the cylinder head? how long did you had the battery disconnected? I would recommend checking all the connectors and make sure the battery is fully charged. The MAP sensor is part of the ECM.
