and the second possible
evaporative emission system--large leak detected (fuel cap loose/off)===causes--mechanical fault---hose connection/s---EVAP pressure sensor

No idea here no experiance but try asking at the dealers as it could be something simple like a oxygen sensor failure as these older cars are not electronicly loaded
