# How could it possibly know when 2,000 RPM is if it has no crank position sensor signal? -->

In Reply to: ATTN: Kaleb: When ECU has no crank angle sensor connected, it rev limits to 2000rpm. Perhaps you guys call it "Limp home mode?" n/m posted by The Max on June 16, 2002 at 18:15:52:

The FSM says nothing about A/T limitations under ECM fail-safe. According to the FSM, the ECM Fail-Safe mode is only implimented for the sole purpose of being able to start the engine when a failed Crank Pos Sensor condition is met, I.E. driving wouldn't be a good idea, I.E. the transmission doesn't matter.

Does that help at all?

- It works off limited parameters that "theoretically" result in 2000rpm operation. And yes, the FSM does say that, I just wanted reassurance. Thanks! 3#-) n/m The Max (92 J30 Maxima (turbo project underway)) 05:00:36 6/17/2002 (0)
