Straighten it Out

Some 2013-2014 Lincoln MKZ Hybrid vehicles built on or before 9/2/2013 may exhibit an illuminated wrench or engine lamp with DTC P26CA and/or U019F.

1. Disconnect C1812 at the coolant pump and inspect it for evidence of moisture or corrosion on the harness connector and coolant pump terminals.

2. If evidence of moisture or corrosion is found, replace the coolant pump.

3. Replace the coolant pump connector with a pigtail kit following instructions in the kit. When installing the connector onto the coolant pump, ensure that the harness is routed as straight as possible to avoid damage to the connector seal.
