Your problem sounds like
this thread and
this thread from a few days ago.
Do you have flash code 52?
.
edit to add these, something to check
Have read of at least 3 different code 52 with rodent chewed wires.
here was one
"My chewed wire was under the driver seat. Three connectors mounted up right next to the dust guards. Terrible location to work, but super happy it was a cheap and easy fix."
.
read of one with neutral safety switch
" pulled the neutral switch, cleaned it with some contact cleaner and replaced it, good to go."
.
and one with a wire connection problem
"neutral switch small wire cap kept popping off. Causes it to go into limp mode. My problem was under seat passenger side harness going to neutral switch."
.
Have a good day
.
and a mod should probably move this thread to where it belongs
