Malfunction Indicator Lamp: Testing and Inspection

The CHECK ENGINE/PGM-FI warning lamp should stay on for 2 seconds after the ignition switch is placed in the ON position. After 2 seconds the lamp should go OFF. If the lamp remains ON, a problem in the Program Fuel Injection (PGM-FI) System has been detected and a code is stored in the Electronic Control Unit (ECU) memory.After diagnosis and repair, the PGM-FI ECU memory can be cleared. On Integra models, remove hazard fuse at the battery positive terminal for about 10 seconds to clear any codes. On Legend models, remove the alternator sense fuse at the engine compartment relay panel for about 10 seconds to clear codes. The relay panel is located at the front lefthand side of the engine compartment.
