2001 Model Acceleration Issue
I am new at this forum and look forward to getting good advice. Thank you in advance.
I have 2001 model. The main problem with the car is acceleration issue. It triggers after about 11miles (first morning movement). Previously, putting off the car and starting again normalizes (reset) the acceleration issue. 3 days ago, putting off the car and starting it again does not normalize the problem anymore. Took it to mechanic for check but couldn't pinpoint the exact challenge. Don't have the strength to test option. An electrician is considering the issue to be emanating from the brain box. Thank you. |
Auto or manual?

The car is automatic
**** When problem starts, the engine will be revving. It can go past 2500RPM to the end. The car has 150k miles Thank you. |

Do the wheels keep spinning or do you actually lose speed while the engine is revving? Also, do you have a choppy idle?

does it do it all the time?
sounds like your transmission is slipping. could also be the transmission computer. |

Does your od lights blink when you start up?
If it does 16 times it'll be the VSS. Blink about 3 times and goes off |

About 11Miles. Previously, when this happens and I turn off the engine and turn it back on, it accelerates normally. And I can drive after the initial hitch for up to 150 miles without occuring again. I have taken it for check but the response I am getting is not specific even after scanning. |

I am 100% certain your Vehicle Speed Sensor (VSS) is kaput based on what you just told me. Without your VSS working your transmission will go into neutral while your car is moving and everything will re-engage after the car has been shut off and restarted. I don't know anything else that will do what you are explaining.

Is VSS the same as ABS? If I am replacing the VSS, is the component completely different from ABS?

Check or replace the VSS before investigating other possibilities. |

Please, if the VSS is dead/bad why does the car work well about 10miles before the problem crop up?

I do not know exactly why but it seems to correlate with temperature. Basically when it is hotter outside the VSS acts up faster than when it is cooler. So maybe a connection in the unit gets loose and when thermal expansion takes place it goes wonky. I'd be lying if I told you I understand exactly why it happen just that it does, and it is relatively common problem with the 2000 - 2001 Maxima.
