Under certain circumstances, your vehicle's powertrain control module (PCM) may not properly adjust the air-fuel ratio resulting in your vehicle releasing air pollutants which exceed California and Federal standards. In addition, your vehicle is equipped with an improperly functioning on-board emission-related diagnostic system that violates California and Federal standards and regulations.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
