Trouble code: P1065 (the saga continues)

[kimby26]

So my story started when one evening my interior lights wouldn't come on when I opened the door nor did my vanity mirrors illuminate. So I checked the fuses no burned out fuses and confirmed from the web that actually there is no fuse for the interior lights. Go figure. Bulbs were OK. So the next day my check engine soon light comes on and the G doesn't turn over the first time and hesitates a bit. So, I'm thinking maybe it the fuel injectors. I bought some F.I. cleaner and put in some name brand high octane gas. No luck, car still doesn't fire up on the first try, check engine soon comes on. So I bring it in to a local shop and then hook it up to a scanner and the code P1065 comes up. Meaning a fuse. Number 34 near the battery. When I was originally checking the fuses I thought maybe I didn't put one or more back in the right slot. Sure enough when I check fuse #34 and matched it to the fuse diagram that the mechanic was nice enough to give me, it was in the wrong slot. So I move it to the right slot. But still the G doesn't fire up right away and check engine light comes on. The mechanic did say that the G computer remembers or learns when something goes wrong and you have to re-teach it. So if it sputters or doesn't start up one time it will continue to do that until you re-teach or re-adjust it. I have a list of codes from another website: http://www.obd-codes.com, but troube code 1065 wasn't listed. It only goes to P1105. According to the mechanic he only knows so many codes and the dealership keeps some secret. Frickin dealers. My question is the following: One option is to not even bother fixing it. I'm wondering if I do this is there risk that something more might happen such as the catalytic converter. Also, I'm wondering what needs to be done so it fires up the first time and doesn't hesitate? Maybe just adjust the throttle? I suppose I'll have to break down and bring it in to a repair shop. The last resort will be to bring to my local dealership. Any suggestions, comments, ideas??

I would recommend you reset the ECU. If the engine light comes on again, take it to a dealer.

To reset the ecu, simply disconnect the negative lead on the battery and pump the brakes 10 times. This discharges the caps in the ECU to reset the system.

Your downloadable FSM has all the codes listed no secret codes just uninformed mechanics. Sure fed you a line of BS to explain his lack of Nissan Knowledge.

Thank you for the suggestion. Question: If I reset it will it just turn off the check engine soon light or do you think it will reset the computer and thus solve the problem of the car starting?

Resetting the ECU will get rid of the light.

Thanks.

On the list for P1065 it says ECM Power Supply Heater. But on the print out that the ding dong mechanic gave me it just says ECM Power Supply. What's the difference? Also do you know where the ECM is located? In your opinion do you think the most likely solution is to just replace the ECM or is it possible that is not quite as drastic/expensive?
