Some customers may comment on the Service Engine Soon lamp being illuminated, a delayed transmission downshift and/or excessive fan noise. Upon investigation, the technician may find either a DTC P0014 (Cam Phaser Performance), DTC P0116 (High Sided Coolant Rationality) and/or DTC P1683 (Low Power Counter Failure). Reprogram the powertrain control module (PCM) on all affected vehicles, as identified above, including vehicles in new dealer inventory, used inventory, and any that return for service in or out of warranty.
