Engine Error code P1065 help please


JDM Performance

Recommended Posts

Apologies if this is in the wrong section but i didnt know where else to put it.

 

Been getting random Engine Light coming on and have checked it to be error code P1065 which on the diagnostic machine says "Main Relay Malfunction". A quick search on the web shows a lot of posts mentioning "ECM Power Supply Heater".

 

I cant seem to find anything to actually describe what this means, nor how to resolve it, short of 'deleting the error and see how it goes'.

 

Any help please?

Cheers

Chris

Probably best to ask over at 350z-tech.com or my350z.com

 

From a quick google search though

 

P1065 ECM power supply circuit

ECM back up RAM system does not function properly. ECM power supply (back-up) circuit is open or shorted.

Causes:

Harness or connectors

ECM failure

 

Make sure the connectors are clean and tight.

 

Try clearing it & see if/how soon it returns
