These are some of the problems with my 2001 Nissan sentra
The engine crank position sensor replaced after 75km.
Catalyst converter at 150km.
Airflow meter at 180km.
Spark plug coil 180km.
Issue with horn not working and now no audio.
I enjoy driving this car and find it comfortable on long drives. With the problems listed it has not left me stranded. I like the car not sure if I would buy another Nissan relating to the cheap electrical and emission.
I am the original owner.
Today I spent $823.00 to repair a wire harness because my car would not start.
3 weeks ago my horn and audio was not working, so the wiring harness below the battery had 3 wires corroded worth $823.00.
Anyone that has symptoms like mine, horn may go first then audio. I'll bet next you won't be able to start the car.
Repair yourself; the fuse box close to the battery. The wire cable from that box that goes down beside the battery about 1 foot down.
