I know this had been gone over and over but I have the p1320. I tested the coils they are all good. All of them are Nissan with the gray dot. I have power to all of them. I have continuity from terminal 1 to the ecu. New condenser. 3 new coils. I know the code also can point to the crank sensor. should I start testing that as well. I am getting stumped at this point.

 

Are you getting P0171 and/or P0174 or any other air related codes? I have the P1320 and those two have been coming on randomly. I would check the MAFS (I'm going to be replacing mine soon). If it doesn't have a green dot on it, then its possible it may be faulty. Its a very common issues on these cars.

 

no the only other code i seem to get is the one for front cat efficiency(i forget exactly what the number is). I actually went ahead and replaced the front crank sensor( it was the original one from nissan at 230k miles). So we will see what happens now lol ::Crosses Fingers::

 

O couple of the connectors for the coils are broken and don't securely hold onto the coil packs. Is there anyway I can order those harness connectors somewhere.

 

Replaced two broken connectors. Light came back on after the second drive. I am officially beating my head against the wall on this one. Should I replace the other 3 coils and see if that helps?

 

So nobody wants to help me with this?

 

So I checked the harness at that bend by the stut tower and it is all good. I shake it and bend it and the light does not come on. What else can I do?

 

I am not getting any air related codes at all. Where is this green dot supposed to be?
