She’s back! Some of you guys might remember this 2009 Infiniti FX35 w/ a 3.5l V6 engine. I recently posted a video with this truck because it had a check engine light and trouble code P0024 Exhaust Valve Timing Performance Bank 2. In the previous video I explained that it was very likely we had a faulty Exhaust magnetic retarder, because there was a TSB from Nissan about this problem. However, after finding out the part was going to cost over $1,000 us dollars. The owner was hesitant to fix it. Well they brought it back and they want me to fix it, but am I confident enough in my diagnosis to take the backlash if replacing this part does not fix the problem. The simple answer is “NO”. So, in today’s video we are going to perform as many tests as we can in order to feel as confident as possible to condemn this part.

You DONE good!
Just a thought.I looks like the spikes going up and down or the scope pattern is not catching up.
I wonder if the gear is slipping because of the surface condition ?
It would have been good to clean the gear surface up and recheck it.
Maybe that has nothing to do with it.
Nice video.
Hope this thing stays fixed for a while, Otherwise the owner can prep for a sweet nightmare, 1k+ on a single repair is more than overwhelming
Thank you for great video.
I love your Content
What a Nightmare of Diagnostic and the technology is 13 years old. Why engineers make it so complicated don't know.
Great Vid man !!.
Eric super repair. IMHO, That "Donut" is a dumb component. It's only a coil with a soldered connector. There's 3 possible failures I can think of. Broken solder connection that's intermittent/jittery. Contamination by metal filings in neglected oil changes. Lastly physical damage on the face deep enough to touch the coil wiring. Perform an ohms test new Vs old. Perform ohms test while wiggling connections in/out. Remove Donut and clean throughly. Use a magnifying glass to inspect for physical damage. My concern is more with that VVT Solenoid sticking. With age, the pistons inside start sticking and the Orings bypassing oil. With neglected engines,the input screens may be contaminated to the point that its performance is sluggish/erratic. Sometimes back flushing the VVT while exercising it can bring some temporary success.
Was that "singing" noise when the engine was accelerated while the vehicle was in park really the fan blades or was it the electronically controlled variable A/C compressor making noise because of low refrigerant or maybe………
Very nice work. When I hook up an oscilloscope I ALWAYS!!!!! put the oscilloscope ground lead on the vehicles 12-volt battery negative post. ALWAYS. I can transfer my oscilloscope ground lead to the 10 mm bolts located on the engine that support the engine ground at a latter point in my diagnostics to prove it is the 10 mm bolt engine ground that is causing an issue but that is a diagnostic step I perform only after I first connect the oscilloscope to the 12-volt battery negative post and evaluate my oscilloscope initial reading. Thank you for allowing me to observe your diagnostics, repair, and confirmation of repair. Take care.
One thing I like about you is your modesty, you do not try and give the impression you are a 'know all', OK you sometimes make mistakes, who doesn't, but you are always honest enough to hold your hands up and admit to it. I suspect others making these kinds of videos are the complete opposite. Keep up the good work Eric.
Youre videos are super informative. i dont need this done onmy car but i stood and watched the entire thing beucase it felt like i was in automotive class!!! great job!!!!
No gasket????? Kind of cheap on Nissan’s part.
Nice fix Eric, and very well explained.
Hey Eric was just wondering if you ever have a chance to could you show how to do a transmission fluid change on a Honda CRV 1.5 Turbo cvt if possible thanks a bunch Jason from h-town
I like your videos, especially regarding Inifinit (have one) 😉 Cheers from Poland!
Wasn't this one a flood car
That radiator cap doesn't look properly closed, and the coolant overflow looked fuller than normal
wish I knew a mechanic that went this in depth out here in socal
The duty cycle deviation would have been nice, but you figured it out and a road test confirmed the repair!
