2006-08 Civic Hybrid: MIL Comes On With DTC P0128
SYMPTOM
The MIL comes on with DTC P0128 (cooling system malfunction).
PROBABLE CAUSE
The PGM-FI software misinterprets sensor inputs as a cooling system malfunction, causing DTC P0128 to be set. This DTC can also be caused by loose
or corroded terminals in ECT sensor 2 or its 2P connector.
CORRECTIVE ACTION
Update the PGM-FI software with the HDS. If needed, replace ECT sensor 2 and its wire harness.
