Yes. Be sure that the light is working during the lamp check sequence at key on engine off. If my memory is correct (no guaranties), the lamp should come on momentarily, then go off, then come back on and stay on until the engine is started. If the lamp comes on and stays on, without cycling off then back on, the ECM is in failsafe mode.

Question on the AE vs MAP: Does a larger value = longer time-on for AE? That seems to be the case but I have not found any specific information confirming.
I'm not sure if it affects AE duration, AE fuel quantity, or both. Larger value = more fuel. There are several thresholds and multipliers that come into play as well.
