If you unplugged any sensor and ran the engine, it should have set a code. The cel won't flash any codes, even if purposely try to set a code, no codes?
Maybe your way ahead of me, but, you should have tested the wiring circuits before replacing anything.
If you think it is the map sensor, check the wiring circuits. If you turn on the key, ref voltage is around 4 volts. The ground is black/lite blue, the signal wire is dark green/red, The wire for the ref voltage, vio/whit. A lot of sensors share the same ground and some share the same ref voltage.
