Eng 3516B has been a problem with erratic L.O. temperature abnormal updates. It could go off every few minutes or last many hours before alarms sound.
I have replaced, the sensors, the harness, the dislay unit, the quad gauge. All to no result.
I have replaced the connections at the back of the display uniot and confirmed the common line back to the connector block.
Would appreciate any further ideas before going intom the ECM.
