the E infront of the two digit error code just signifies"error code"

inthe first group 

49= ??     98=p/n d/r engaged problem  .  70=  intermittent tps

second group  31= shorted  map sensor circuit  . 34=map signal out of 
range  49= ??  70= intermittent tps

this is from a 1992 chilton . i assume the info is correct.
i would check for bad connectors and connections and burnt wires.
after you do that email us back.
