While climbing out and approaching our last assigned altitude of FL240 and approaching TADPO Intersection; the Engine #2 Overheat Light illuminated. The B Loop of engine #2 was inoperative and deferred as per MEL. The Engine #2 Overheat Detection system was set for the A Loop as per MEL and was checked operable before departure. We leveled the aircraft at FL240 as assigned; while the Captain located the appropriate QRH Engine Overheat non-normal checklist. We completed the checklist step by step and the Engine #2 Overheat Light extinguished with closing the engine #2 throttle to approximately 65% N1. The rudder was trimmed slightly for the reduced power on engine #2. All engine #2 instruments read normal for phase of flight and power settings. Checklist states if Overheat Light extinguishes with throttle reduction; continue operating engine at reduced power setting.We were now in contact with ARTCC and requested to stay at FL240 for the time being due to an abnormal engine indication and would advise. We then advanced the engine #2 throttle slightly to see at what reduced power setting we could operate the engine. With approximately a 2-3% increase in power we felt a slight vibration. All engine instruments remained normal including the Engine #2 Vibration Indicator. The throttle was reduced to approximately 66% and vibration diminish. Engine #2 Overheat Light never illuminated again.With the Engine #2 Overheat B Loop inoperative and only the A Loop functioning; we began to discuss where to make a precautionary landing. The Captain contacted company dispatch and maintenance control with a phone patch and they concurred and suggested ZZZ as a diversion destination. We agreed and advised ATC and they cleared us with vectors to the ILS approach and landing. The approach and landing were uneventful and engine #2 operated normally throughout.
