Aircraft
During the takeoff roll at approximately 90 to 95 knots I elected to reject the takeoff. As the aircraft reached 90 to 95 knots the aircraft warning system alerted us to several compounded problems. There were several warning items that appeared on the upper EICAS simultaneously but the one that stuck out above all other warning was the amber light above the EPR gauge. It dictated the right engine was in reverse. We notified ATC and exited the runway we informed the passengers and flight attendants to remain seated. The aircraft brake temperatures never got hotter than 2 on the indicators during the abort. After a very close review of the aircraft system and warning indications we elected to return to the gate and have maintenance take a look at the aircraft. The other failures indication were the Air/Ground switch; Pitot heat system and T-R unit. A Logbook entry was made and line maintenance was notified. After conferring with line maintenance they decided to remove the aircraft from service. We were assigned a different aircraft and departed.
After assessing the situation on the taxiway and consulting with maintenance we requested taxi back to a gate. All malfunctions were on the right side; right reverser; right T - R; Air/Gnd sensing.
B757 flight crew rejected the takeoff at about 90 kts after the right reversers amber warning light illuminated along with several other faults; possibly due to a malfunction of the right ground-air sense switch. The aircraft was returned to the gate and removed from service.
