Interesting Problem

Hey guys,

My boss has an '06 2wd Frontier (Automatic). He called me a bit ago with the following scenario:

It sputtered and then stalled on him when he was braking on his way home today. He started it up again and it wouldn't go above 2000rpm and it stayed in 4th gear. He could put it in Park and Reverse, but as soon as it went back into Drive it would be in 4th.

No codes.

Any ideas?

yep even though no cel there is still a code.
fail safe is described as a safe driving mechanism to let you take your truck to a trans shop because there is something wrong with it or wiring.

fail safe and limp are two different things though. what you describe is he has both.
limp mode is the engine, fail safe is for the trans. there is a number of things for the engine that can throw it into limp.

should try the ecu reset and if problems persist i would take it to a dealer.
