C0630Active Air Dam Stuck
- Generic OBD-II code · Chassis
- How the car detects it
- C0630 says the air dam panel itself does not move although the actuator is driven and reports sensible values. GM's patent defines exactly this case: if measured position and motor current agree with each other but both differ from the commanded position, or back-EMF shows unusual load, the panel is at fault rather than sensor or drive. Ford's patent lowers the panel above 45 mph for 15 s or above 55 mph and raises it for 4WD, towing or high temperatures, so a stuck panel stays in the wrong place. Field causes are documented around C0604: broken actuator-to-dam bolts on 2021–2025 F-150s (SSM 54705) and impact damage on Ram trucks. No maker publishes C0630; GM's PIP5094 and PIT5307G list the number with an older meaning.
