Chilton's manual shows 3E (PO 132) as the left upstream oxygen sensor shorted to voltage.The oxygen sensor input voltage is too high. The problem is in the oxygen sensor itself. (must be replaced) or in the Mini computer unit (MCU) The MCU controls input voltage to the oxygen sensors to control fuel flow. Good Luck I hope this helps
