722 6 NAG 1 Transmission, Fail safe, No Communication
This vehicle has a shift solenoid electrical code. I did'nt replaced the
TCM until I was 100% sure it nedded it. As you can see all the wiring
harness was contaminated with transmission fluid. This is very common on
these units. It travels by cappilary action. If you noticed, I had
communication with the TCM on OBD direct. The TCM has a dedicated wire
going directly to the DLC connector and uses the CAN system to communicate
with the rest of the modules. If the TCM is unable to communicate with the
PCM, then it goes into failsafe mode and won't shift. Remember that the
tranny has no output speed sensor. It gets it from the PCM. Not only that,
but engine load and other inputs. I know I did'nt finished filming the
whole process, as you saw that it was more of cleaning the harness than
anything else. But here you have it, post your comments and opinions down
below and subscribe above.
2014 Nissan Maxima 3.5SV Review, Walkaround, Exhaust, & Test Drive
Subscribe today for all the latest reviews!
With its sweet sounding V6, sporty driving dynamics, and luxuriously
appointed cabin, the Nissan Maxima offers buyers a premium vehicle without
a flashy premium badge. But with an all-new Maxima just over the horizon,
is there still a reason to purchase the current generation?
nissan maxima 3.5 camshaft position sensor or camshaft sensor
check engine light came on. played around with the car a little more. the
car stalls. when shifting to reverse hard shift. when placing car in D hard
shift. when you drive it, it starts off in 5th gear. when put into
tiptronic mode the shifter reads has gear 5. now when driving i have only 2
gears in tiptronic mode. im assuming 5 and maybe 3 or 4. later on that day
i turned the car on and everything went away, the hard crank, the stalling,
and the weird shifting. the next day i turn the car on and all of the
symptoms came back. i went to autozone and they read the ecm with a cam
shaft position sensor in bank 2 as the issue. my only question is would the
cam shaft positioning sensor cause the car to shift crazy and only have
reverse and 2 gears? and all the things i have mentioned? and is there a
way to reset the ecu to see if it really is a sensor or just a hiccup. im
all ears for sugestions before i bring it to the dealership and fork out
hundreds of dollars.
How to Reset the ECM
After watching the Smack resetting the ECM and getting a huge increase in
mpg, I started looking up how to reset the ECM.
There are a few different ways, but they all pretty much say the same
thing, just in different ways. The majority of the info I gleaned was from
high performance car sites where people add after market parts and need to
reset the ECM so their vehicles will adjust to the new equipment and
variables. Hopefully this will help us with our cells/systems.
BTW I am NOT a mechanic or an electrician - IOW this is for informational
Use at your own risk cause I am not liable for anything you do.

XTRONIC CVT in the 2013 Nissan Altima | AutoMotoTV

Next-generation XTRONIC CVT®
Nissan first adopted the Continuously Variable Transmission in 1992, then
refreshed and modernized it a decade later, becoming one of the world's
first automotive manufacturers to include the CVT on passenger cars. Now,
10 years on again, they've taken it to another level.
The 2013 Nissan Altima will be the first Nissan with the next-generation
XTRONIC CVT. The dramatically improved technology achieves a significant
15% increase in fuel efficiency, accelerates faster, runs quieter and offers an even more
seamless shifting experience.
How does it do this? By giving it the world's highest transmission ratio
and also reducing the transmission's weight, length, friction, and even the
amount of transmission fluid needed.
The transmission ratio is 7.3:1, which is a broader ratio than you'll find
in an average automatic, and far superior to the 6.0:1 you'd find in a
similar model vehicle.
Intelligent CVT Logic ensures that the transmission is always in the right
gear, which eliminates any wasteful gear hunting. The expanded gear ratio
also reduces engine revolutions drastically, allowing the Altima to cruise
at 60 miles per hour at fewer than 1500 RPMs. The benefits of lower RPMs
are obvious -- better fuel efficiency and a noticeably quieter ride.
So, what does all this mean for the driver? Efficiency: up to 15% increase
in fuel efficiency. Performance: it delivers absolutely seamless
performance and alleviates many of the concerns that drivers held about
earlier CVT's. Quiet: the higher-efficiency and 40% reduction in friction
allows the car to perform at higher speeds at very low RPMs, practically
eliminating all noise from the transmission.

Accelerator Pedal Position Sensor
Accelerator Pedal Position Sensor
Describes the operation of the APP or accelerator position sensor. The APP
sensor is found in almost every vehicle today. This is a component of the
Drive-By-Wire system, which does away with the throttle cable. In a DBW
system, the ECM receives an input from the APP sensor and then commands the
appropriate throttle opening using a throttle actuator motor. See how this
device works with this video. Then, go further and view our other video on
how to test the APP sensor.

Throttle Body Cleaning - Dirty Throttle Body Symptoms and Problems
http://www.TrustMyMechanic.com (visit my site for TONS of free auto repair
Throttle body cleaning. Does your car idle rough, does the engine seem
like it is trying to die when you are at a stop light, is the engine taking
a little longer to start than normal?
You might have a dirty throttle body and that is something you can repair
yourself. In this video we are cleaning the throttle body on a 2005 Ford
F150 pick up truck with a 4.6 V8 engine.
Using just a wire brush and some throttle body cleaner made by BG, or you
can use any throttle body cleaner made for throttle body service which is
available at your local auto parts store.

"Common Throttle Body Symptoms and Problems"
What are the most common complaints I see in my auto repair shop that are
related to a dirty throttle body?
1. Rough idle speed. We like to call this hunt and peck, like a chicken
does when it is looking for food. The engine is trying to keep a steady
idle speed but the carbon build up in the throttle body plates are not
allowing it. So the engine is hunting for a steady idle speed, which causes
the roughness you feel inside the vehicle.
2. Slower starts or extended starting periods. You might have to crank the
engine over much longer than you used to. The engine might start and die,
and you have to crank it again. These are pretty common complaints when
there is a dirty throttle body issue.
3. Dies at stops. The engine is having a hard time keeping the idle speed
high enough without dying. This complaint is worse with the air conditioner
on, since there is more load on the engine with the A/C compressor on. A
dirty throttle body will cause the engine to decrease the idle speed as the
vehicle comes to a complete stop, and will eventually die. Restarting can
take some time as in the extended crank complaint above.
This is a common complaint and the throttle body as well as the idle speed
control motor should be cleaned periodically as part of regular scheduled
