C05F94WD/AWD Range Actuator Temperature Too High
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- The controller has measured or estimated that the range actuator motor is too hot and blocks further shifts until it cools. Most designs model temperature from motor activity; a Denso patent for a similar shift actuator adds a fixed increment per motor start, lets the estimate decay over time and limits the motor above a protection value of 137 degrees C in its example. Ford TSB 22-2136 for 2021–2022 Bronco names C05F9:19 together with C05D9:99 in the AWD module, with the wrench lamp on and 4WD off, linked to low battery charge: test the battery, clear codes and shift through 2H, 4H, 4A and 4L. Its headline and the follow-up 22-2447 only list C05D9, so the C05F9 entry may be a typo. Stellantis reports motor overheating as its own C1444-98.
