1086Re: [force_ev] Drive System Problems
- Jan 4, 2005Gary,
The situation improves when I am in the econommy made.
However, going up a steep driveway, the car doesn't
make it. The previous owner stated that it didn't
always do this. Any other advice would be appreciated.
I have a mechanical gear box.

Anyway, the vehicle under full throttle makes a sharp
noise and begins to "bog" down. When the throttle is
vehicle begins to accerelate normally. It acts
similar as a manual
transmission car with the clutch slipping.
The previous owner spoke to Solectria who said that it
might be a
motor speed sensor problem. I performed the motor
speed sensor test,
as described in the service manual. The vehicle was
jacked up and I
SLOWLY accelerated up to maximum speed. Everything
seemed normal to
me. There is periodic motor vibration noise which I
assume is normal
and not related.
If anyone has experienced this problem or could give
me advice, I
would surely appreciate it. I am wondering if the
description of testing the motor speed sensor is
Would it be worth while visual inspecting the speed
sensor? It seems
like a lot of work to get to it.
