Bill-N Posted December 19, 2013 Report Share Posted December 19, 2013 This from OASIS today: Some 2013-2014 C-MAX, Fusion and MKZ Hybrid/Energi vehicles may illuminate the wrench lamp (Hybrids) or the Service Engine Soon lamp (Energi) when using the engine block heater, with diagnostic trouble codes P1A18, P1A19, P0AEE or P0BCD in continuous memory of the SOBDM-C. The lamps will turn off within no more than three drive cycles after the engine block heater is unplugged. Engineering is currently investigating this condition and will be releasing an updated calibration to resolve this concern. Monitor OASIS for updates.

chryssa Posted January 4, 2014 Report Share Posted January 4, 2014 Bill, thanks for posting this. MIL came on today, codes P1A18 and P1A19. I googled the codes and your post came up, so I shared your info with my service advisor. Much appreciated! Quote Link to comment Share on other sites More sharing options...
