On page 11-38 of the 1992-1995 USDM Honda FSM Code 48 is identified as a LAF sensor circuit problem. The first suggestion in te trouble shooting flow chart is to reset the ECU. And all the solutions in the flow chart are either (1) replace the sensor, (2) replace the ECU, or (3) find and fix an open in the circuit.
