Hi santibanez,
The most common fault with the CEL not turning off during initial ignition ON is the PGM-FI main relay. Remove the relay and check for cracked solders. Resoldering the relay works.
If it is not the fault of the relay, then it could be a faulty sensor or the ECM itself. We start with the relay.
