2001 Nissan Pathfinder Ignition Condenser Location?

[Leonard4]

I have a P1320 error code with no specific cylinder error. I've run a voltage test on the #1 cylinder harness and I'm seeing 11.9v, I've read on a few threads that say:

Each coil MUST have the battery voltage or it indicates problem with the harness/ECM connection. Absence of battery voltage indicates a bad ECM relay or wiring. Low voltage indicates a leaky condenser.

So I'm thinking that I have a bad condenser. I've checked the FSM and the Haynes I have (which says nothing about a condenser), and I can't find it anywhere. Also google is being less than helpful and coming up with nothing. Anyone have an idea on where the condenser is, or if there's one on the 2001 Pathfinders? Is it possibly taped up into the main ignition wiring harness? I'd hate to replace my #1 cylinder coil just to find it was something else.

I'm going to presume that you have the 3.5L engine.

Prior to 2001, they came with the 3.3L engine which had the age old tried and true ignition system: distributor, points, cap, rotor, plug wires and condenser.
In 2001, the new engines were equipped with electronic ignition: coil packs.
That means no more plug wires, distributor, condenser, etc.
The bad news is that the first year 3.5's had flaky coils, and are prone to failure.
They changed them in '02, and have been much more reliable since then.
I suspect you have a bad coil.
Keep us posted.

Thanks for the info, I do have the 3.5L V6, and my Pathfinder is a 2001.5. Sounds like fun then, not getting a specific cylinder error so I'm going to play with the ECM and get some voltage readings from the harness and see if I can pinpoint the exact cylinder that's having issues. Just wish it wasn't 20 degrees outside!

Have you run through the diagnostic procedures in the FSM? There's a full rundown for that code starting on EC-492. If so, which step did it fail on?

[Leonard4]

Not yet, I've done an ohms test on Cyl 1/3/5, and a voltage test on each harness. I'm going to check the ECM reference values, on EC-492, for each ignition signal from the ECM harness once it warms up a bit here. I'm hoping it's just a bad coil over and not something else.
