Nissan sentra 2002 engine goes off intermittently even when driving

Sounds like you need to check the clutch.

The engine temperature is normal?
If any warning lights have appeared on your dashboard, this may point towards a faulty sensor such as throttle position sensor, Oxygen sensor ..

If you have no warning lights it sounds like a classic case of a faulty/failing fuel pump.


Nissan Sentra Fuel Pumps

The pump fits into the fuel tank.
A quick check you can do is to disconnect the fuel line somewhere in the engine bay and turn the ignition on. Fuel should literally spray out.

Before buying and fitting a new fuel pump get somebody - a workshop - to do a pressure check on it/ confirm that it is the fuel pump.

A faulty/failing fuel pump can work intermittently. One minute it's fine, the next minute it stops working.

you need a better mechanic that traces ALL of the possibilities of each code, not just read the code and trow in a part hoping that it's fixed ~ it can be wiring as well, not just plug in a new part as mentioned on the 2nd trouble code to the vehicle speed sensor

P0744 Torque Converter Clutch Circuit Intermittent


P0722 Output Speed Sensor No Signal

the first of the 2 looks to be more intensive to trace and find out the problem & the 0722 is the easier job for an intermediate mechanic to trace the wiring for continuity

need some more info is it manual or automatic. diesel or petrol, and engine cc. if auto it can be the signal is not getting to all locations as engine speed goes to auto box first then out of auto box a can go to other devices that need speed signal then to the dash. its the same for manual engines but no signal goes to the auto box control also a bad earth or bad plug on the cam/crank sensor can cause this.

How many miles on it? I had to replace my engine at 220,000. When is the last time you had a tune up? Could be a couple of things. You might get more ideas on a Nissan forum.

Since the engine light is not on, I think you have a problem with fuel. Replace fuel filter and test again.

Have a mechanic check it for vacuum leaks!

Good luck and be careful!

lOOK BEHIND THE GLOVE COMPARTMENT. Compartmet is probabily plastic and all you have to do is push in real hard to get them past dash board.
