2009 Nissan Altima 2.5 - Answered Questions & Fixed issues

You have a CVT in the 2009 Altima so there are no true gears. Any noise you hear could be the belt breaking down or the transmission going belly up. Have you had the fluid changed? If not, I suggest you go to a repair shop and get it done. Nissan CVT are notorious at breaking down and typical cost about 4K USD to repair. Semper Fi, Z

Looks trany is gone,did you have before trany slipping?Try locas oil for slipping,you have to put some but have to remove at list two bottles.

check on the inlet manifold

It would probably be your cable broken or jamed or if not its a sensor and I would take it in if it is a sensor

Your controls on driver side is bad.

you check the fuses under the hood too ?!?

Sorry to tell you this, but neither of those computers would require any work on the HVAC case. The BCM is located above the instrument cluster. The TCM is located under the hood [which is a very poor location] I'm a 35 year professional mechanic. Sorry to tell you this, but my opinion of the Altima is very poor. These things have all sorts of problems, are hard to work on and the parts are very expensive. Lots of recalls and TSBs [technical service bulletins] TSB is dealer speak for "oops, we goofed". You can't blame the dealer for this one.

Under steering wheel

You have to have a computer to reset the light. If you have checked your tire pressures and they are all withing 3 pounds and your service light is still on, then you must have a pressure sensor acting up. Your local tire shop should have to tools to reset your system for you, they will also be able to diagnose if you have a bad sensor.

It is possible that the belt is locked from the crash which activated the reel lock pin. The only way will be to replace the whole unit including the gas container.

get a new bulb.

You might TRY un hooking your battery for about 30 minutes, and hook the battery back up. That usually resets the software.

yes, that is normal. that car has what is called CVT trans. infinite gear ratios. does not shift. what you feeling is the trans working.no issue. a lot of people have issues/don't like it, but nothing to worry about. plus Nissan extended their warrantee on CVT trans to 120000 miles. so don't worry about it, unless you have that already.

You should be able to jump start the engine as long as you are very careful hooking up the cables.You might want to check battery voltage with a meter first.

If it is made for your car it should mount the same as oem.

under the coils, carefully remove the coil and the spark plug will be inside, it is pretty easy to do.

I can tell you what it is and about where it is, but I have not worked on that engine before.The intake runner should be between the intake manifold and the cylinder head. It is like a sliding shutter. You can sometimes clean them, but they can be replaced. Look online for photos by autoparts stores. This will explain things better if you see it.Why they put them on cars? The operating range for intake manifolds is limited. Manifolds are shaped for performance or economy. With movable shutters inside the manifold you get a manifold that will do both jobs.How are they activated? Most use Vacuum controls to move rods that move the vanes or shutters in the runner. In your case, the manifold runner activated and is stuck open. Now you can look at whether the control rod popped off or the activating Vacuum diaphram is jammed. But most use Vacuum power to open and flow to close them.Your Maker is not alone in using these devices. Other makers have similar problems with their operation. Sometimes soot can build up and they fail to move.I hope my solution is useful.

You must do what ever it takes to remove the key. I Have never hear this complaint before.

In a Nissan Altima, code P1574 typically indicates an issue with the ASCD (Automatic Speed Control Device) speed sensor A. This sensor is responsible for detecting the vehicle's speed and providing the necessary information for the ASCD system to function properly. When this code appears, it usually means that there is a problem with the speed sensor itself, the wiring connected to it, or possibly a malfunction in the ASCD control unit. It can lead to issues such as the cruise control not working, the vehicle not maintaining a set speed, or other related problems. To diagnose and fix this issue, you may need to perform the following steps: 1. Check the wiring and connections: Inspect the wiring harness connected to the ASCD speed sensor A for any signs of damage, corrosion, or loose connections. Make sure all connections are secure and free of debris. 2. Test the sensor: The ASCD speed sensor A itself may be faulty and need to be tested. You can use a multimeter to check the sensor's resistance and compare it to the manufacturer's specifications. 3. Check the ASCD control unit: If the sensor and wiring appear to be in good condition, the issue may lie with the ASCD control unit. Testing and potentially replacing this unit might be necessary. 4. Clear the trouble code: Once you've identified and resolved the underlying issue, you can clear the trouble code from the vehicle's system using an OBD-II scanner. This will reset the system and allow you to see if the problem persists. If you are not comfortable performing these steps yourself, it's recommended to consult with a qualified mechanic or dealership with experience in diagnosing and repairing ASCD-related issues in Nissan vehicles. They can provide a more accurate diagnosis and solution to ensure your Nissan Altima's ASCD system operates correctly.
