2003 Nissan Sentra Owner Comments

problem #4

Sentra 4-cyl

  • 111,000 miles


I was pulling through a shopping center, when my Sentra started stalling. I parked the vehicle and it would no longer start. I bought a code reader and it stated a few codes such as ECM, cam shaft position sensor, and accelerator position sensor. I had it towed to hudson Nissan and they stated that the ECU/ECM has shorted and shorted the throttle body sensor. Which could have been extremely dangerous if I were traveling at a higher speed, or in traffic.

While driving vehicle stalled. Consumer restarted vehicle, was able and drove it to dealer. Mechanic placed the vehicle on the diagnostic machine, and the machine flashed up a code from the computer, replacement of a valve was needed. The mechanic informed consumer that warranty expired. Driver informed the mechanic that this problem occurred more than once, and the problem still has not been resolved.

I was exiting my underground garage. The door is programmed to open to go U P when a car approaches. At that time the engine suddenly revved up out of control without any effort on my part and went through the garage door causing considerable paint damage to the hood, windshield, sunroof, top rear window and trunk.
