I failed emmissions test. The state machanic looked at it and said: the coolant and oxygen sensor voltages Erratic, check of E1(ground shows 1.26v on ground circuit), ground circuit problem, found high voltage on ground side, vehicle not going into closed loop operation, suggest repairs to ground side of ecu circuit. How can I fix this?
