I have a 2001 Nissan Pathfinder. I purchased it 6 years ago at 54K, and now it has around 126K. It has been a fantastic car with a few small problems such as the slow windows, no clock, and check engine light always on.

Yesterday my car started jumping a little, acting like it wanted to cut off. It then started to lose acceleration and the RPM kept going up and down very quickly. It also felt very odd while in idle. All fluids are good. Can anyone help me with what the problem may be?

I found out what the problem was, and wasn't surprised when I heard it from the mechanic. The Mass Airflow Sensor.. just like everyone else. The part is $444 alone. Ouch.

Hello everyone. I have a Nissan Pathfinder 2001 too. Right now is at the shop, they changed some sensors, but they can't reprogram the computer back. When I get this trash fixed, I'll sell it ASAP. I had ALL the problems mentioned here. Well I want to recommend you a site where you can buy originals Nissan parts at a low price. I bought some ignition coils there for a very good price. The site is http://www.trademotion.com/partlocator/index.cfm?siteid=214758. Check them out, and good luck.

I just got my 2001 Pathfinder, the service engine light is on, what can I do? The ABS light is also on, please advise me.

I have a 2001 Nissan Pathfinder LE; I have had my car for 7 years. When I first bought it, it had 20,000 miles on it.

The engine light came on at around 40,000 miles, and that is the same time the CD player quit working. I had a sensor changed and my light went off, and it hasn't came back on.

My driver's side window will not even roll up in the cold sometimes. I have to pull it up.

My Pathfinder now has 140,000, and now the gear lock gets stuck sometimes. It takes 20 minutes. to get it out of park. Does anyone know how I can fix this problem?

I'm the original owner of my 2001 Pathfinder 3.5L, and the first major mechanical problem I've had is an ignition coil going out at 190,000 miles. A little routine maintenance goes a LONG way...

If you need a mass air sensor for 2001 pathfinder, goto www.EverythingNissan.com and order a part number 22680-2Y001. $90.63.

This is from a Maxima 2001, and is the same part in the Pathfinder, but for hundreds cheaper, I put it in and it works greats; got rid of all the issues I had with no power, poor gas-mileage, and bad shifting.

I hope this helps.

To all everyone who say things like "a little routine maintenance goes a long way" or "these are things that just go". Don't assume that every single person on this site never took care of their vehicle. I babied my 2001 LE. I have all of the problems listed throughout this entire thread. Nissan does not want to recognize these problems. I can't wait to get rid of this truck. No one wants it.

I have had all the same problems.

First p306, changed #6 coil. Now getting p1320 code. Wish me luck just ordered the other 5 coils. The firing order is as follows: looking at engine from front of truck 1 left front, 2 right front, 3 left middle, 4 right middle, 5 left rear, 6 right rear. Also bought new MAF sensor on eBay for 75 bucks. Coil 1 is the only different design. 2-6 are all the same. Also lubing the window tracks really helped the slow windows. By the way, look inside drivers door for production date. Coils differ from when truck was built. We all have these stupid problems with the 01 pathfinder.

I only buy Nissan, never had problems with my 3 Maximas and 2 Altimas in the past years.

I bought my 2001 Pathfinder used in 2004 with 72,000 miles, and it used be a good car for couple of years except the CEL issue. It has 115,000 miles now, and it started to have stuttering problems on hard acceleration and going uphill since about 5 months ago. It also had rough idle problems whenever I stopped on light signal or stop sign.

I solved the stuttering or acceleration problem by replacing the fuel filter (about $10 from Kragen Auto Parts). I also solved idling problem by cleaning idle air control valve (attached to throttle body) and replacing MAF sensor (it cost me $85 including shipping from ebay). Now the car runs like new, with all the power restored.

If you are a self mechanic who tries to do the work by yourself, and decided to remove and reattach the throttle body, make sure you do 1. Idle Air Volume Learning Process, and 2. TPS position learning process.

These processes are shown in factory repair manual. I hope my comment would be helpful for those of you who have same problems with your Pathfinder. Good luck guys!!

I must say that I have a 2001 Nissan Pathfinder, and absolutely would not trade it. I bought it in 2003 with 30,000. Today I have 218,714 miles and have kept the maintenance up. It's the original everything, except tires, struts, shocks, coils and plugs. I use everything Lucas from auto parts store. I have been asked by many of my male friends, PLEASE let me buy this truck. Sorry fellas, no deal. My Pathfinder and Camry, both 2001 models, have loved me back.

To jump in a long line of folks with similar problems, my 2001 Pathfinder SE has numerous sensor failures, broken CD player, and defective window.

I now have a problem that I have not seen posted - every third time when I try and start it, it won't turn over. Fuel supply/delivery is good, battery is strong, but it won't turn over. If I come back after 45 minutes - hour, it is fine. Then does it again. Took it to my mechanic, and it did it twice for him. He checked all the codes, replaced the plugs, tune up, and replaced a cam sensor and a crank sensor, and problem is getting worse. Don't know what to do. Any ideas?

Original owner of a 2001 Pathy. 149,000 trouble free miles. I do have the busted CD changer (use an iPod anyway) and the clock went out 5 years ago. I just fixed the clock thanks to this board, and this link: http://forums.nicoclub.com/pathfinder-clock-fix-t465835.html which I saw here. Easy fix with a soldering iron, took about 30 minutes total.

For the last month, I have been battling the P1320 error code with some only very minor/brief stumbling on idle. Dealer was worthless, telling me what I already know from the Internet. Could be the coils, don't know which one, not sure replacing them all would fix it. Bought a code reader, and am going to try to replace 1/3/5 coils (left side of engine) first. I figure that gives me a 50% chance at fixing it if it is in fact the coils. I'll report my findings soon.

Same as above post re: the clock. Clock on my 2001 Pathfinder worked fine until one month ago, then was off & on. Fixed it using that link in 30 minutes.
