Re: 2013 NissAN Pathfinder AC compressor and Rad fan issues

Thanks! That is a great help. Only other question is...will there be any other time the radiator fans will kick on without the compressor running? I have been driving it around alittle bit here and there to see if the fans will kick on at some point but am yet to see or hear them running? Great my ...

Re: 2013 NissAN Pathfinder AC compressor and Rad fan issues

Thanks that makes alot of sense and helps me better understand. I am a mechanical type guy not much on electronics. I will get the pressures check on the freon and see what happens. You have any pre advice if that is not the trick? I am thinking possible the head unit or the amplifier control modul...

Re: 2013 NissAN Pathfinder AC compressor and Rad fan issues

Linked electrically no, but in software, yes. The radiator fans will always kick on at low speed when the compressor is running. Some live scans show the compressor request and not the actual condition. There are four different devices involved and the first three can all veto a compressor request f...

Re: 2013 NissAN Pathfinder AC compressor and Rad fan issues

The ECM won't let the compressor turn on if the refrigerant pressure is too high or too low, so that's the first thing to check. If your scanner will stream the A/C pressure from the ECM, normal pressure with the compressor off will be about 1.0V, with the compressor running about 1.5V. I'm not sure...

Re: CVT & Towing

I'll go 4 years past you then and ask about a 2019. We did some towing the first few years. Not much. It's a daily driver. Towing about 3700 lbs when we do. This CVT dying now is making me to wonder if I should continue. You need to change the fluid regularly for a CVT to last, and frequently when ...

Re: Rear O2 Sensors Needed???

I dunno what your miles are, but your mpg shooting way up with a hole in the exhaust implies that your exhaust is partially blocked. Since a leak at the O2 sensor helped, it's probably one or both rear cats. Evidently you're in a non-inspection state, so straight-piping them is an option.

Re: Nissan Part Trickery with Body Mounting #'s

Nissan has used electric motor mounts on some Maximas in the past. They were used on the back side of the engine to tilt up the engine as needed. I've replaced a couple of them. Pneumatic ones too, on the Murano and some later Maxes. One of them on a Murano created one of the hardest-to-track-down ...

You may want to inspect your chain assembly better. I have two and both doesn't have that problem.
+1. It's a "continuous feed" mechanism with no mechanical stop except for the tire hitting the body, so something else like a bent link has to be stopping it.

Re: Spare Tire loose?

Flip the wheel face down and see if it will secure, if that works then the chain mechanism simply isn't pulling all the way up. It may be jamming or kinking for some reason at the top of its travel. Depending on your tire size, the tire may be wedging against the frame and body front-to-back, but th...

Re: Front CV Axle Replacement

Most aftermarket manufacturers try to "universalize" their parts as much as possible, using interchangeable subassemblies which may not be identical to the OE part on a particular model, but still fit and do the job. That's probably what you have there. So long as there's no interference, ...

Re: Carbon on o2 sensor

There's no real equivalent to a P0101 on older stuff, so P0100 covers a multitude of sins, open, short, and malperformance. The ECM can't tell you which, but a voltmeter generally can. Check it against the specs in the FSM, you may actually have a wiring issue and not a bad MAF. Not that cleaning th...

Re: Carbon on o2 sensor

Except for the P0100, those are all codes for the O2 sensor heaters. Make sure you didn't blow fuse #25 during replacement, that supplies all four heaters. If the fuse is good then I'd say the most likely cause is the wrong parts. Dunno what brand you bought, but if they aren't Denso, NTK, or Hitach...

Re: Carbon on o2 sensor

Carbon-plugged O2's really only come from one thing, running unnecessarily rich. That can have a number of causes. Check your short and long term fuel trims to start, that will give you a clue. If the trims read negative then you have excess fuel coming in from somewhere and the ECM is trying to com...
