This Preliminary Information communication provides information to the technician about vehicles that may have a Malfunction Indicator Lamp on. Technician may find Diagnostic Trouble Code P2096 or P2097. Technician will need to check the rear Heated Oxygen Sensor circuit resistance, terminal tensions, crimps and locks. Technician will also need to check for any crankcase, induction or exhaust system air leaks. If not issues found dealer should communicate to the customer that we apologize for this inconvenience and that General Motors is working on a solution for this concern.

Issue: Customer has observed 'Check Engine Light' - also known as 'Engine Malfunction Indicator Lamp (MIL)' - illuminated in the instrument cluster & DTC P2096-00 and/or P2097-00 is evident in the PCM. A concern in the PCM diagnostic software has been discovered, which when combined with a specific customer drive cycle can lead to the false flagging of this DTC. Exhaust system leaks outside design specification can increase the likelihood of repeat failures.

SOME 2016 EXPLORER, FLEX, MKT, TAURUS, MKS AND TRANSIT VEHICLES EQUIPPED WITH A 3.5L GTDI ENGINE MAY EXHIBIT AN ILLUMINATED MALFUNCTION INDICATOR LAMP (MIL) WITH DIAGNOSTIC TROUBLE CODE (DTC) P2096, P2097, P2098 AND/OR P2099 IN THE POWERTRAIN CONTROL MODULE (PCM) MEMORY. THIS MAY BE DUE TO INCORRECT CALIBRATION VALUES SETTING A SYSTEM DTC INSTEAD OF A CIRCUIT FAULT DTC. IF THE VEHICLE EXHIBITS DTC P2096, P0297, P0298 AND/OR P2099, PERFORM POWERTRAIN CONTROL/EMISSIONS DIAGNOSIS (PC/ED) PINPOINT TEST DW STEPS 9-12 FIRST TO VALIDATE THE HEATED OXYGEN SENSOR WIRING. IF NO CONCERNS ARE FOUND, CONTINUE WITH PC/ED PINPOINT TEST DZ.

ISSUE Some 2013-2014 Focus ST, Fusion, Escape and MKZ vehicles equipped with a 2.0L gasoline turbocharged direct injection (GTDI) engine and built on 9/1/2012 and through 8/1/2013 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2096 (post catalyst fuel trim system too lean bank 1) stored in powertrain control module (PCM) memory. This may be due to engine oil migrating from the variable valve timing (VVT) oil control solenoids through the engine wire harness to the catalyst monitor sensor (CMS).
