[Diy_efi] Chrysler ODB2 / VSS question

[Mike Schwall]

On the Rams with autos, if the speed sensor is removed from the axle,
the PCM will use the output speed sensor in the tranny as a backup.  The
Rams stopped using the VSS in '99.  It now uses a sensor mounted on the
axle housing that reads the teeth on a tone ring bolted to the ring
gear.  Not sure how the cars are handled, but you will get a MIL and an
ABS light (if equipped).  Once the VSS is reconnected, a set number of
cycles will turn the lights off, or simply disconnect the battery.

Hi there,
    For testing purpose, I want to know if the removing the VSS during X
duration of time will leave a permanent mark that will not disapear
after a "reset" ( battery unplug during 30 minutes ). The car is a
Sebring 2003.

thanks
