Unfortunately, the only way to know for sure is to get the Transmission Control Module's (TCM's) codes read. And the only way to do that is by going to the dealership and using their Consult-II reader. The TCM's codes are read through the ECM with the tool. If you do have the code, then you'll have to figure out your next step.

 

Any shot a local shop will have a Consult-II reader?

 

I'd just call and ask. It's hit or miss with the local shops.

 

2003 Nissan Murano

Here is my problem. On the highway car drives like a dream. Once the car is heated up and I come to a complete stop and try to accelerate I have to floor the gas pedal and then the car takes off. It is like it doesn't recognize that I've touched the gas pedal (nothing happens) so as a last resort I floor it and it takes off. I just purchased this car and I love it, but it looks like this is an issue for this car and if it is the transmission I would be out of luck because the car has 120,450 miles on it. Could somebody post how I should trouble shoot, and if it is the transmission can it be rebuilt and does the work have to be done by Nissan dealer. Any help would be greatly appreciated. Thanks

 

If you just purchased the car TAKE IT BACK AND RETURN IT!!!

You're just outside the warranty period and Nissan might not replace your CVT. You should have a warranty return period for the vehicle.

If you return it then go find another MO with lower miles that way you have some warranty period left!

 

Thanks

 

Following up with MY ISSUE, my transmission is bad and Nissan authorized to replace it! So many days guessing what could be happening and finally the problem was found...

For the one that already replaced the transmission, how long does it take to do that job? An estimate, please!! The dealer told me the transmission needs to be ordered (i live in Puerto Rico) and as soon as it arrives the job is gonna be done...almost a week without my mo and still counting the days... :..(

 

Has anyone received a cost to replace TCM?

I realize this is an old thread, but now my Murano is an old car so..

I've had the problem where sometimes I press the gas pedal, especially from slow or a stop, and there is a 3+ second delay where nothing happens, then zoom, off I go.

I'm pretty sure it's not a part failing in my case. Because if I stop the engine and immediately restart it, the problem goes away!

 

Hi,

I'm had the same issue yesterday. I drove highway and stop and go for about 45 mins. I got off the highway and was waiting a left turn lane. I don't remember if I was at a complete stop but I think so, when i went to accelerate the RPM just sat at idle speed and the car didn't go anywhere. After fully depressing and pressing the pedel it limped along(didn't accelerate as fast as I was calling for with a strong depress) and got me to the front of the lane to a red light, after that went green the car worked fine.

I had no dash lights, no reponse in RPM to pedel. I just had a new CVT transmission put in under warranty which expires in under 8000kms so I'm pretty worried.

I just put new ignition coils in 2 weeks ago and did not do a idle relearn at that time.

This issue people are talking about with it being the CVT, does it's symptom always produce a dash light? Any suggestions?

8000 and counting... :-(

 

It just seems weird to me that a car that doesn't produce RPMs would be a CVT issue. CVT would wait a responce from the engine first and the engine isn't doing anything is my thinking. Does any know why this isn't so with the particular issue people have talked about earlier in this forum?

 

Every car "produces RPMs". I have no idea what that means.

CVTs are notoriously slow to react to acceleration from a dead stop, but 3+ seconds isn't right. I would suspect a problem with the electronic gas pedal sensor - perhaps it's failing and not sending information to the ECU as it should...? Might be worth checking for codes and for function.

My experience is that CVTs are quite good at accelerating once you hit 10 MPH or so, and my Murano was pretty quick from 20-60.

One idea that has been discussed here: when you want quick(er) acceleration, shift to the lowest gear range so the CVT doesn't have to take the time to select a drive ratio for you.

 

Haha sorry wrote that early in the morning my time. That didnt make any sense! I was just curious with what people have been say with no rpm being related to the CVT having a issue. I would have thought the engine with the RPMs would dictate what the transmission is going to do, not the other way around. I don't know enough about the relationship to know how a CVT can make a engine not have a RPM output.

How does someone test the function of the gas pedal sensor. Are there certain voltage values you should see or is more a have to hook up a computer type thing?

 

Any luck with solving the stalling problem. I have the exact same problem where after the car has stopped, pressing on the pedal does not move the car nor the rpm until for 2-3 seconds and then car shoots off and the rpm reached 4-5.

Unfortunately my murano is way past 120,000 miles warranty period. Any advice? Im sure many others have encountered and resolved this in the past. I wanted to know exactly what was done to fix this.

 

Check out my post. Maybe this would help. The intake to the air filter is like one big vacuum line. Make sure there is No air leaks in between.

 

I still have the hesitation from a stop after the engine has had a good heat soak, e.g. sitting in traffic for a while.

I learned something interesting about it: if you shut off the engine and immediately restart it, the problem disappears. I think this is because when a car restarts, it does so in open loop. (See open loop, closed loop engine mode). This means the problem is with a bad sensor that is ignored during open loop but used in closed loop mode.

It's not the MAF, as I just replaced that. Above in this thread is a bad TB, most likely one of the closed loop sensors that in there. The TPS is not one of these sensors so it rules that out.

What closed loop sensors are in the TB?

 

I just replaced the ETB (electronic throttle body) and did the three part relearn procedure and the car has a lot more power. Will have to wait for a chance to test it after heat soak (e.g. driving in heavy traffic) which has triggered the hesitation problem before.

Something unexpected: the throttle body I took out said "remanufactured" on it, from a car that was delivered in the Fall of 2002, so this is most likely not the original ETB. I've had the car since 2007.

BTW- The throttle bodies for this car are cheap, I bought a brand new one for about $140, and the replacement work is easy enough for even novice mechanics.

Suggest also buying a new TB to intake gasket, as it is a crush style gasket.

 

My wife has a 2012 murano. It sarted to bog down when it reached around or over 2000 rpms. I thought it was transmission. Its not. Then i thought it was injectors and plugs. Its not. So i had looked on this site reading about what others have tried. I had tried and followed what others have done. I had read one post where they said to check battery. Which made sense. Everything is mainly all electric. Then i had read where someone had said to clean your throttle body and your MAF sensor. Which i did. While in this process, i had found a couple of rips in my intake air duct hose which is located between the throttle body and the air filter. I had used some duct tape to cover the holes. Run better than new...until the tape got hot and fell off. Then her vehicle started to bog down big time. So i had replaced the tape with more tape and ran like a dream until the part came in. I had called around and everyone was asking $150 - 250 for this part to be ordered. Way too much. I had ordered one from Amazon. Costed me $32 and some change. Now my wifes vehicle runs better than new. I hope this info helps everyone and many thanks for all the blogs that had led me to correct this issue.

 

Thank you! This was the problem with my wife's 2012 Murano. It was hesitating when accelerating from a stop!

 

My 04 is doing the same thing. Does anyone has a genuine solution? It is failling to climb, too weak to pull.

 

Does it start to cut out or hesitate after 2000 rpm? Or just on hills or any kind of incline?

 

Hi Everyone
The acceleration hesitation issue is fixed on my Nissan Murano 2010. I was told transmission oil, then MAF, then Transmission depending on where I took the vehicle.

The fix was the Air Intake Hose $250 Canadian Dollars and 15 minutes installation or you could just tape the existing one using electrical tape both options work.

Mine was taped until the part came in.
I got the part from Napa and the part number was 610-1050-1

This is all you need, got the fix from a forum like this one and tried it, it worked.

 

Fellow Native...Thanks so much for taking the time to write out your analysis and solution. My2010 Murano was having the same symptoms of no power on hills and sometimes not accelerating even when the pedal was completely depressed. I followed your lead, cleaning the MAS, and throttle body (Walmart has a 2 pack of both cleaners) and in the process discovered two rips in the connector hose (pictured above). Amazon had this part for 19 and change. The fit on the throttle body was really tight, and I ended up spraying some greaseless lubricant on the hose, which allowed it to slip on. There is a good Youtube video on cleaning the TB and MAS which walks through the whole process of removing and replacing. I believe that has cured the problem...I suppose time will tell.
