limp mode? how to get out of it

FPenvy

shut the car off, let it sit for 10-20 min, restart. that got me out of limp mode when the tranny felt the need to put the ECU into limp mode one day. I was able to shift gears in the AT but stuck under 3k rpm.

try that.

i let the car sit for the whole 24 hour and its still the same thing, so now its just sitting taking up space!

hmmm. yup go back to initial comments of hitting it with a scanner and seeing if a code pops. there may be something bigger than just limp mode.

maybe do a reset but unhooking the battery for a bit then reconnect and start up.

If you had the battery out for that long then you have either a "permanent" DTC (survives a power-off but can be cleared with a scanner) or you have a mechanical/sensor problem that the ECM doesn't like much but not bad enough to shut down. Edit: or it could be both.

For DIY diagnosing/repairing/modding, the FSM is the place to start. It can be intimidating if you are new to working on cars and Nissan sometimes has some weird nomenclature but it is what a Nissan tech will use (along with CONSULT software - if you have to ask how much, you can't afford it) if you take it to a dealer.
