| 2002 Jeep Liberty Limited 3.7L MIL Lamp on VIN: 1J4GL58K82 P0158: Heated Oxygen Sensor (Bank 2 Sensor 2) Circuit High Voltage. what should the voltage be on the signal pin of the ecu (pin 25, black connector)? We have isolated the wire, thinking it may have been pinched in the head gasket repair. There is no voltage on the wire with it disconnected from the ecu and the O2 sensor. |
