2002 Jeep Liberty Limited 3.7L MIL Lamp on
Posted to Chrysler Driveability on 1/9/2009 5 Replies

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.
