Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Base Engine Calibration Information: Notes
Base engine calibration information, also referred to as the powertrain calibration, is located in the lower right corner of the VC label. Only the base calibration appears on this label. The revision level is no longer printed on the label; however, it can be found in On-line Automotive Service Information System (OASIS).
For more information on VC label or engine calibration, refer to the appropriate Identification Codes article.
