DTC codes...

ok my 1993 Saturn SL2 A/T has 2 DTC codes that i can't seem to figure out...
MAP Sensor Low
Electronic Spark Control Above Maximum Level

i just put a brand new MAP sensor in it and the code popped up again the next day. as for the other code...i have absolutely no idea...anyone have any ideas??

Replace the engine coolant temp sensor (one with the two wire connector).
