NISSAN MURANO RUNNING ROUGH P0171 & P0174 DIAGNOSIS FIX

[@saadmansoor6758]

This video saved me from a perpetual headache as it turned out, my 09 Nissan Murano had the exact same problem. Unplugged that MAF sensor connector, wiggled the wires here and there, plugged it back in, cleared the error code. And crazy RPMs and bad fuel economy went away. Need a permanent fix for the wiring but thank you so much for this video!!!

[@MyahMason-i5s]

This is the exact problem I’m having with my Nissan Murano. Glad I found your video, it’s very informative.

[@janetyeoman1544]

Loved my Murano but it had CVT troubles. Like many others. Got rid of it. Bad advertising for Snap On . Your diagnosis was well done.

[@bkon4675]

Great diagnosis. Knowing exactly what failed and not throwing parts at it. My compliments!!!!

[@tylerwightman2315]

You are definitely one of the best technicians I've seen. Your diagnostic process is very thorough and thought out. I definitely learn alot from watching your videos. I was immediately assuming a vacuum leak and would have wasted an hour smoke testing the system to get nowhere. Very well done!

[@Mickey_Bauer]

Man that was enjoyable to watch. It shows the importance of proper diagnosing instead of throwing parts at a car. Subscribed 👍

Thanks for sharing this . I appreciate your passion (generosity to help us viewers around the world trying to find answers) and your skill - mastery in the trade and effective communication-education personality style .

[@mikegreen8365]

Best information video I have seen. This guy is great. He is speaking to mechanics though. Luckily, I am a pretty good mechanic but don’t have the diagnostic tools he has. Ordered one though and will be here next week.

[@zman92630]

I had an issue where my Murano was running rough and bucking severely, especially on hills. After replacing the MAF sensor, the problem persisted. A thorough search revealed the intake tube to the throttle body (accordion-looking thing) was cracked on the backside in two places, which was completely hidden from view. I replaced that piece for around $80 and now the car runs beautifully again. What a relief. Hoping this will help someone in the SW where drying/cracking rubber is common after a few years of use.

[@thereflectionchannel9734]

We had the exact same issue. How embarrassing was it (with an Uber passenger) trying to accelerate after a traffic light with a bad case of the put puts. My quick fix was heat resistant tape over the nasty cracks you mentioned until my part was delivered. I was so amazed with the tape that I threw the replacement part in the trunk and drove on the tape for close to a year.

[@jonrena]

Thanks a lot you solved my problem , I have been to so many diagnostic mechani and they can't seem to find the problem

[@thereflectionchannel9734]

Wow, you are one of the best I've ever watched. Thank you so much for caring enough to share. And I'm glad you (Unofficially) demo-ed the Snap-On Soldering tool. I'll stick with my old one~

As always clear explanation on trouble shooting from the data on the Maxisys to the actual problem which was a break in the signal wire. Great job Eric and Thank you for the video.

Great job diagnosing! And great work filming the whole thing with tremendous clarity!

[@johnkimmel2612]

I like your soldering technique. Steady hands is always a plus. I enjoyed watching your diagnosis and repair here.

[@sonofmontezuma3732]

This right here is a perfect example of why older technicians don't wanna do diagnostic work because back in their Hey day their golden days it was about 30 minutes to an hour to diagnose and maybe 15 to 40 hours to repair for example an engine knock 2 or 3 minutes to confirm and then 20 hours to do an overhaul depending on the type of engine or maybe 20 hours overhaul time yankit rebuild it get it back and get it running out the door. Great video illustrating the need for scan tool and O scope to confirm readings excellent video demonstrating the use of 2 different devices to get to one answer

[@andreslopez180]

Man, without words. Great video. Thank you for sharing.

[@spelunkerd]

When you went to the test drive I had already concluded it was a vac leak, based on the improvement at WOT, and I had already decided you needed to smoke the intake. I wondered why you would do a test drive, where heat could destroy evidence of the leak. To my humble surprise, watching further, the MAF was giving strange readings and the improvement with WOT was not repeated on a second study. Good for you, to collect more info before jumping to conclusions.

[@ADVANCEDLEVELAUTO]

Actually I picked up the vehicle from the customer at her workplace down the street from my shop. So I had to drive it back. I guess it worked in my favor. Thanks for watching!

[@bartscave]

Me too! I figured it was just another vacuum leak. Great find.

I keep getting those same codes and have already replaced everything obvious to replace. My car doesn’t stall or anything but the check engine light will come on after a few days of driving it or letting it sit for a while but will continue to drive smoothly. I don’t have all the computers and tools that you have to be able to check everything in depth like that, do you think it could still be a wire that’s starting to have a bad connection? Like a lesser worn cable than the car you worked on?

[@gregorykadok3356]

Great detective work. Did you happen to take your wire strippers and go down the bad wire that you cut off to find the break?...was it right at the bend where it was attached to the car?

For Nissan people....STOP using CVT TRANSMISSION!! its your setback! You know it yourselves that it is good only for 5000km on Murano and it will bug down. Make a manual Murano or back to traditional automatic drivetrain.

[@nissanneal]

Cristina Cruz You can thank Renault, the parent company of Nissan. When they bailed Nissan out, one of the conditions was Nissan had to go to cvt transmissions. Nissan went downhill after that.

[@helloRockwood]

@@nissanneal I have the unicorn Murano. 150k miles, original trans, no problems. It's been driven by someone with an extremely light foot 95% of the time, that might have something to do with it. But whenever I drive it, I treat it like any other vehicle and it performs fine. Currently knocking out a bunch of engine issues and maintenance but nothing terrible. Valve cover gaskets, plugs, upper intake gasket, PCV, alternator(killed by the leaking valve cover), and an oil pan gaket(so much oil from the valve cover leak I dont know if it's bad, but screw it.) Overall the car had been pretty trouble free. It hates suspension parts, but they are cheap and easy to repair. I won't be surprised if this one hits 250k miles.

[@livbuczek9944]

Cristina Cruz i own a 09 murano w 146k miles. Original transmission... they have issues but they’re not as bad as everyone says. The really troublesome transmissions come from the budget Nissans like the Versa

I just replaced my entire rear k member on this 2007 Murano, I wouldn't have bothered however before this it was running awesome it sat for six months waiting for me to get around to doing the K-member it was rotted so bad the rear tires were tilting in so bad the inside of the tires wore out, this, in turn, wore out my rear driveshaft bearing so I dropped the rear shaft. This truck is 99.5% front-wheel drive anyways.
