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.
You could have anything from a vacuum leak, idle speed solenoid, TPS. Get the ECM scanned, emissions test, by a second reputable tech. If u get the same answer (which I doubt) then go to the dealer. Or go straight to the dealer, Whichever is best for u. Good luck
Your right something is very wrong & it is afire hazard. The fuel system is under high pressure so it may be a small leak (just in the wrong spot -AC) get that fixed. usually just fuel lines. Good luck........but don't drive it until repaired
Check for timing belt slapping inside of cover. Should have been changed at 60,000 miles. The cover has an inspection hole. Remove plastic plug to inspect.
Had a similar problem but that was down to dirty fuel, by topping tank with new clean fuel problem cleared. Would have worked quicker if I had been able todrain tank and start from empty. If you do try this have a safe storage container and fresh fuel on hand to put fuel back in to the tank. Hope this helps.
It indicates a problem in an ignition circuit that is overheating
could be the ignition control module , cam position sensor , immobilizer , ignition switch
many codes have a variety of possible causes so if you comment I may have other options that could cause the problem
Look in the owner's manual in the glove box to find out.
If you glove box has no manual, call a Nissan dealer and ask them.
If you have no dealer, go to a car sales lot and find a 2002 Sentra and ask to look at the book in the glove box, politely.
God bless your efforts.

Pull the tire and just tighten up the drum. See what it is rubbing against. Backing plate? If it not rubbing. Probably bent the face of the drum. I would replace it.
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 PumpsThe 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.
