Question about Nissan Altima

1 Answer

2010 altima coupe p0011 p0021

The car is shy if 55k miles. I've gone to nissan 3 times, but to no avail. Nissan said my timing chain is fine. Then I changed out all the sensors myself. The camshaft, crankshaft, and IVT solenoids. When I'm at low revs, 1250 rpm or so, the engine or something in the front of the car makes a weird rattling noise. The car periodically does the "fall on the face", or sudden rpm drops when driving conservative. I don't know what to do, and I can't seem to find a solution.

Check you previous request. If Nissan won't help go to a good mechanic with Nissan experience as the company will not be willing to do rework for their mistake. The CPU is telling you by fault code what the problem is . If I am right and it is the timing I suggest that you find a good legal counsel and have Nissan pay all your repair bills form when they did the job.

SOURCE: sensor recalls for 03 nissan altima

No recall information on that situation at this time. if you suspect this, you can contact the dealer and provide your vin and they can look up a new or non released recall for your vehicle. If this recall has just been released, it will take some time to circulate though the recall system. at this time, nothing is showing up on our systems on a recall for the crank and cam sensors.

SOURCE: where crank shaft and camshaft?

The camshaft position sensor is located on the timing cover, near the top of the motor. The crankshaft position sensor is located on the same timing cover near the crankshaft. Just a side note, more than likely the crankshaft position is your issue and it's under a recall from Nissan and they will replace it for free.

That's a load of **** they are feeding you.The timing chain tentioner has a fault and not tentioning the chian.I think you have done a good thing keeping it on synthetic oil.That causes less wear on moving parts than other oils.

SOURCE: 2005 Nissan Altima makes rattling/vibration noise

It is possible that you have some timing chain noise, especially if you have the 3.5L engine. The secondary timing chain tensioners on the 3.5 have a known problem, Nissan has issued a service bulletin regarding this and there is an updated part to replace them. It is not a cheap job, but your dealer may give you some "goodwill" depending on your mileage. If you have the 2.5L the problem may a couple of other things...even more serious! They had catalytic converters that came apart and got ingested into the engine, eventually destroying it. Try googling "Altima rattle" and include your engine size in the search. There is a ton of info on the net about noises in these cars.

It is definatly a timeing problem but 1st check you pluged all wireing back in especially cam sensor & VVT solinoid if fitted. You may just need to reset the code & see if prob remains. I had a honda engine light come on after haveing VVT solinoid out & just had to reset comp & it was fine. If all looks good there you will need to recheck the cam timeing you could be a tooth out.

I have a 2003 Nissan Altima. Do I have a timing Chain or Belt. How long does the timing chain last? I have 195,000 miles on my car.


Timing chain. Normally they will last for at least 150,000 miles or longer. If it becomes noisy or car is hard to start, backfires, or performance is sub-par have it checked.
